Relation to heredity

The study of instinct is in the genetic treatment of evolutionary

science a study in heredity. The favouring bionomic conditions are those

of a relatively constant environment under which relatively stereotyped

responses are advantageous. If the environment be complex, there is a

corresponding complexity in instinctive behaviour. But adjustment to a

complex environment may be reached in two ways; by instinctive

adaptation through initially stereotyped behaviour; or by plastic

accommodation by acquired modifications. The tendency of the evolution

of intelligence is towards the disintegration of the stereotyped modes

of response and the dissolution of instinct. Natural selection which,

under a uniform and constant environment, leads to the survival of

relatively fixed and definite modes of response, under an environment

presenting a wider range of varying possibilities leads to the survival

of plastic accommodation through intelligence. This plasticity is,

however, itself hereditary. All intelligent procedure implies the

inherited capacity of profiting by experience. Instinctive in the

popular sense, it does not fall within the narrower definition of the

term; it is more conveniently described as innate. It is important to

grasp clearly the distinction thus drawn. A duckling only a few hours

old if placed in water swims with orderly strokes. The stimulus of water

on the breast may be regarded as a sensory presentation which is

followed by a definite and adaptive application of behaviour. But this

specific application is dependent upon a prolonged racial preparation of

the organism to respond in this particular way. Such response is

instinctive. It is wholly due, as such, to racial preparation. Compare

the case of a boy who learns to ride a bicycle. This is not wholly due,

as such, to racial preparation, but is also partly due to individual

preparation. The boy no doubt inherits a capacity for riding a bicycle,

otherwise he could never do so. But he has to learn to ride none the

less. Individual experience is a condition which without the innate

capacity cannot take effect. Instinct involves inherited adaptation;

intelligence, an inherited power, embodied in the higher nerve-centres,

of accommodation to varying circumstances.

INSTITUTE (from Lat. _instituere_, to establish or set up), something

established, an institution, particularly any society established for an

artistic, educational, scientific or social purpose. The word seems to

have been first applied in English to such institutions for the

advancement of science or art as were modelled on the great French

society, the _Institut National_ (see ACADEMIES). It is thus the name of

such societies as the Royal Institute of British Architects, the

Imperial Institute and the like. It is extended to similar

organizations, particularly to educational, on a smaller or local scale,

such as Mechanics' or Workmen's Institutes, and is sometimes applied to

charitable foundations. In the United States the word is, in a

particular sense, applied to periodic classes giving instruction in the

principles of education to the teachers of elementary and district

schools. The term "institute" is often used to translate the Lat.

_institutio_, in the sense of a treatise on the elements of any subject,

and particularly of law or jurisprudence; thus the compilation of the

principles of Roman law, made by order of the emperor Justinian, is

known as _Justinian's Institutes_, and hence Coke's treatise on English

law, of which the first part is better known as _Coke upon Littleton_,

is called _The Institute_. The same title is borne by Calvin's work on

the elements of the Christian doctrine. In Scots law "institute" is the

person named, in a settlement or testament to whom an estate is first

limited; those who follow, failing him, are termed "substitutes."

INSTITUTIONAL CHURCH, the name generally applied both in the British

Isles and in America to a type of church which supplements its ordinary

work by identifying itself in various ways with the secular interests of

those whom it seeks to influence. The idea of such extension of function

grew out of the recognition of the fact that the normal activities of

church work entirely failed to retain the interest of a large class of

the population to whom the ritual formality of ordinary services was

unacceptable. Various attempts were made to overcome this deficiency,

e.g. by modifying the form of service or of some services, by the

addition to the ordinary services of more or less informal meetings

(e.g. the Pleasant Sunday Afternoon services), by specially excusing

persons from wearing the normal church-going attire in holiday resorts,

and by holding services out of doors. The principle underlying all these

changes is systematized in the Institutional Church which, in addition

to its main building for specifically religious services, provides

other rooms or buildings which during the week are open for the use of

members and friends. Lectures, concerts, debates and social gatherings

are organized; there are reading rooms, gymnasiums and other recreations

rooms; various clubs (cycling, cricket, football) are formed. The

organization of the whole is subdivided into special departments managed

by committees. By these various means many persons are attracted into

the atmosphere of the church's work who could not be induced to attend

the formal services.

This expansion of normal church work may be traced back in England to at

least as early as 1840, but the full development of the Institutional

Church belongs only to the latter years of the 19th century. The chief

example in England is Whitefield's Central Mission in Tottenham Court

Road, London, a church which, in addition to an elaborate organization

on the lines above described, has an official journal. In the United

States the movement may be said to date from about 1880. The name

"Institutional" was first applied to Berkeley Temple, Boston, by Dr

William Jewett Tucker, then president of Dartmouth College. The obvious

criticism that this epithet emphasizes the administrative and secular

side to the exclusion of the spiritual led to the tentative adoption of

other titles, e.g. the "Open Church," the "Free Church," the former of

which is the more commonly used. In 1894 was formed the "Open and

Institutional Church League" at New York, which held a number of

conventions and served as a headquarters for the numerous separate

churches. In connexion with this league was formed the "National

Federation of Churches and Christian Workers," which held a convention

in 1905.

W. Mead, _Modern Methods in Church Work_ (New York, 1897); R. A.

Woods, _English Social Movements_ (New York, 1891).

INSTRUMENT (Lat. _instrumentum_, from _instruere_, to build up, furnish,

arrange, prepare), that which can be used as a means to an end, hence a

mechanical contrivance, implement or tool; the word is more particularly

applied to the implements of applied science, in mathematics, surgery,

surveying, &c., while those of the handicrafts are generally known as

"tools." A specific use of the term is for the various contrivances used

to produce musical sounds, "musical instruments."

In law an "instrument" is any formal or written document by which

expression is given to a legal act or agreement. This is a classical use

of the Lat. _instrumentum_, a document, record. The term may be used in

a wide sense, as a mere writing, meant only to form a record, or in a

particular sense with reference to certain statutes. For example, the

Stamp Act 1891 defines an instrument as an expression including every

written document; for the purposes of the Forgery Act 1861 a post-office

telegram accepting a wager has been defined as an instrument. In

expressions such as "deed, will, or other written instrument" the word

means any written document under which a right or liability, legal or

equitable, exists.

INSTRUMENTATION. "Instrumentation" is the best term that can be found

for that aspect of musical art which is concerned with timbre. The

narrower term "orchestration" is applied to the instrumentation of

orchestral music. Since the most obvious differences of timbre are in

those of various instruments, the art which blends and contrasts timbre

is most easily discussed as the treatment of instruments; but we must

use this term with philosophic breadth and allow it to include voices.

Instrumentation is in all standard text-books treated as a technical

subject, from the point of view of practical students desirous of

writing for the modern orchestra. And as there is no branch of art in

which mechanical improvements, and the consequent change in the nature

of technical difficulties, bear so directly upon the possibilities and

methods of external effect, it follows that an exclusive preponderance

of this view is not without serious disadvantage from the standpoint of

general musical culture. There is probably no other branch of art in

which orthodox tradition is so entirely divorced from the historical

sense, and the history, when studied at all, so little illuminated by

the permanent artistic significance of its subjects. When improvements

in the structure of an instrument remove from the modern composer's

memory an entire category of limitations which in classical music

determined the very character of the instrument, the temptation is easy

to regard the improvement as a kind of access of wisdom, in comparison

with which not only the older form of the instrument, but the part that

it plays in classical music, is crude and archaic. But we should do

better justice to improvements in an instrument if we really understood

how far they give it, not merely new resources, but a new nature. And,

moreover, those composers who have done most to realize this new nature

(as Wagner has done for the brass instruments) have also retained, to an

extent unsuspected by their imitators, the definite character which the

instrument had in its earlier form.

As it is with mechanical improvements, so is it to a still greater

degree with changes in the function of timbre in art. Throughout the

19th century so fatal was the hold obtained on the popular mind by the

technical expert's view of instrumentation, that it was impossible to

hear the works of Handel and Bach without "additional accompaniments"

conceived in terms of art as irrelevant to those of 18th-century

polyphonys as the terms of Turnerian landscape are irrelevant to the

decoration of the outside walls of a cathedral. There is some reason to

hope that the day of these misconceptions is passed; although there is

also some reason to fear that on other grounds the present era may be

known to posterity as an era of instrumentation comparable, in its

gorgeous chaos of experiment and its lack of consistent ideas of harmony

and form, only to the monodic period at the beginning of the 17th

century, in which no one had ears for anything but experiments in

harmonic colour. We do not propose to concern ourselves here with those

technical subjects which are the chief concern of standard treatises on

instrumentation. Our task is simply to furnish the general reader with

an account of the types of instrumentation prevalent at various musical

periods, and their relation to other branches of the art.

_The Vocal Style of the 16th Century._--In the 16th century

instrumentation was, in its normal modern sense, non-existent; but in a

special sense it was at an unsurpassable stage of perfection, namely, in

the treatment of pure vocal harmony. In every mature period of art it

will be found that, however much the technical rules may be collected in

one special category, every artistic category has a perfect interaction

with all the others; and this is nowhere more perfectly shown than when

the art is in its simplest possible form of maturity. Practically every

law of harmony in 16th-century music may be equally well regarded as a

law of vocal effect. Discords must not be taken unprepared, because a

singer can only find his note by a mental judgment, and in attacking a

discord he has to find a note of which the harmonic meaning is at

variance with that of other notes sung at the same time. Melody must not

make more than one wide skip in the same direction, because by so doing

it would cause an awkward change of vocal register. Two parts must not

move in consecutive octaves or fifths, because by so doing they

unaccountably reinforce each other by an amount by which they impoverish

the rest of the harmony. Thus we justify, on grounds of instrumentation,

laws usually known as laws of harmony and counterpoint. Apart from such

considerations, 16th-century vocal harmony shows in the hands of its

greatest masters an inexhaustible variety of refinements of vocal

colour. A volume might be written on Orlando di Lasso's art of so

crossing the voices as to render possible successions of chords which,

on a keyed instrument where such crossing cannot be expressed, would be

a horrible series of consecutive fifths; the beauty of the device

consisting in the extreme simplicity of the chords, combined with the

novelty due to the fact that these chords cannot be produced by any

ordinary means without incorrectness.

_Decorative Instrumentation._--In the 17th century the use of

instruments became a necessity; but there were at first no organized

ideas for their treatment except those which were grounded on their use

as supporting and imitating the voice. The early 17th-century attempts

at their independent use and characterization are historically

interesting, but artistically almost barbarous. Sometimes they achieve

rare beauty by accident. Heinrich Schutz's _Lamentatio Davidi_ is

written for a bass voice accompanied by four trombones and organ. The

trombone parts are on exactly the same material as the voice, which in

fact forms with them a five-part fugue-texture. The effect is

magnificent, and admirably suited to the dignity of the trombone.

Moreover, the opening theme is formed of slow arpeggios; and the more

modern harmonic elements, though technically chromatic, consist, from

the modern point of view, rather in swift changes between nearly related

keys than in chromatic blurring of the main key. All this, especially in

a writer like Schutz, who is saturated with every progressive tendency

of the time, seems to point to a deep sense of the appropriate style of

trombone writing. Yet, so insensible is Schutz to the euphony of his own

work, that he proposes, as an alternative for the first and second

trombones, two violins an octave higher, the other parts remaining

unaltered! Imagination boggles at the vileness of this effect.

The chief work done in instrumentation in the 17th century is

undoubtedly that of the Italian writers for the violin, who developed

the technique of that instrument until it proved not only more

resourceful but more artistically organized than that of the solo voice,

which by the time of Handel had become little better than an acrobatic

monstrosity. In the art of Bach and Handel, instrumentation, as

distinguished from choral writing, has attained a definite artistic

coherence. Choral writing itself has become different from what it was

in the 16th century. The free use of discords and of wider intervals,

together with the influence of the florid elements of solo-singing,

enlarged the bounds of choral expression almost beyond recognition,

while they crowded into very narrow quarters the subtleties of

16th-century music. These, however, by no means disappeared; and such

devices as the crossing of parts in the second Kyrie of Bach's _B Minor

Mass_ (bars 7, 8, 14, 15, 22, 23, 50) abundantly show that in the hands

of the great masters artistic truths are not things which a change of

date can make false.

But the treatment of instruments in Bach and Handel has a radical

difference from that of the art which was soon to succeed it. It has

precisely the same limitation as the treatment of form and emotion; it

cannot change as the work proceeds. Its contrasts are like those of an

architectural scheme, not those of a landscape or a drama. It admits of

the loveliest combinations of timbre, and it can alternate them in

considerable variety. Modern composers have often produced their most

characteristic orchestral effects with fewer contrasting elements than

Bach uses in his _Trauer-Ode_, in the pastoral symphony in his

_Christmas Oratorio_, in the first chorus of the cantata _Liebster Gott,

wann werd' ich sterben_, and in many other cases; but the modern

instrumental effects are as far outside Bach's scope as a long passage

of preparation on the dominant leading to the return of a first subject

is beyond the scope of a gigue in a suite. Bach's conception of the

function of an instrument is that it holds a regular part in a

polyphonic scheme; and his blending of tones is like the blending of

colours in a purely decorative design.

Those instruments of which the tones and compass are most suitable for

polyphonic melody are for the most part high in pitch; a circumstance

which, in conjunction with the practice (initiated by the monodists and

ratified by science and common sense) of reckoning chords upwards from

the bass, leads to the conclusion that the instruments which hold the

main threads in the design shall be supported where necessary by a

simple harmonic filling-out on some keyed instrument capable of forming

an unobtrusive background. The chords necessary in this part, which with

its supporting bass is called the _continuo_, were indicated by figures;

and the evanescent and delicate tones of the harpsichord lent themselves

admirably to this purpose where solo voices and instruments were

concerned. For the support of the chorus the more powerful organ was

necessary. It is in the attempt to supply the place of this _continuo_

(or _figured bass_) by definite orchestral parts that modern

performances, until the most recent times, have shown so radical an

incapacity to grasp the nature of 18th-century instrumentation. The

whole point of this filling-out is that, the polyphonic design of the

main instruments being complete in itself, there is no room for any such

additional inner parts as can attract attention. In the interest of

euphony some harmonious sound is needed to bridge the great gap which

almost always exists between the bass and the upper instruments, but

this filling out must be of the softest and most atmospheric kind. Bach

himself is known to have executed it in a very polyphonic style, and

this for the excellent reason that plain chords would have contrasted so

strongly with the real instrumental parts that they could not fail to

attract attention even in the softest tones of the harpsichord or the

organ, while light polyphony in these tones would elude the ear and at

the same time perfectly bridge over the gap in the harmony. There seems

no good reason why in modern performances the pianoforte should not be

used for the purpose; if only accompanists can be trained to acquire the

necessary delicacy of touch, and can be made to understand that, if they

cannot extemporize the necessary polyphony, and so have to play

something definitely written for them, it is not a mass of interesting

detail which they are to bring to the public ear. A lamentable instance

of the prevalent confusion of thought on this point is shown by the

vocal scores of the Bach cantatas corresponding to the edition of the

_Bach Gesellschaft_ (which must not be held responsible for them). In

these Bach's polyphonic designs are often obliterated beneath a mass of

editorial counterpoint (even where Bach has carefully written the words

"_tasto solo_," i.e. "no filling out"). The same comments apply to the

attempts sometimes made to fill out the bare places in 18th-century

clavier music. There is no doubt that such filling out was often done on

a second harpsichord with stops of a very light tone; but, if it cannot

be done on the modern pianoforte in a touch so light as to avoid

confusion between it and the notes actually written as essential to the

design, it certainly ought not to be done at all. The greater richness

of tone of the modern pianoforte is a better compensation for any

bareness that may be imputed to pure two-part or three-part writing than

a filling out which deprives the listener of the power to follow the

essential lines of the music. The same holds good, though in a lesser

degree, of the resources of the harpsichord in respect of

octave-strings. To sacrifice phrasing, and distinctness in real

part-writing, to a crude imitation of the richness produced mechanically

on the harpsichord by drawing 4-ft. and 8-ft. registers, is artistically

suicidal. The genius of the modern pianoforte is to produce richness by

depth and variety of tone; and players who cannot find scope for such

genius in the real part-writing of the 18th century will not get any

nearer to the 18th-century spirit by sacrificing the essentials of its

art to an attempt to imitate its mechanical resources by a modern _tour

de force_.

_Symphonic Instrumentation._--The difference between decorative and

symphonic instrumentation is admirably shown by Gluck. In the famous

dedicatory letter of his _Alceste_ he mentions among other conceptions

on which his reform of opera was to be based, that the co-operation of

the instruments ought to be regulated in proportion to the interest and

the passion, a doctrine of which the true significance lies in its

connexion with other conditions of opera which are incompatible with the

polyphonic treatment of instruments as threads in a decorative scheme.

The date of this famous letter was 1767, but after _Alceste_ Gluck was

still able to use material from earlier work; and the overture to

_Armide_ is adapted from that of _Telemacco_, written in the year of

Bach's death (1750).

To write an account of symphonic instrumentation in any detail would be

like attempting a history of emotional expression; and all that we can

do here is to point out that the problem which was, so to speak, shelved

by the polyphonic device of the _continuo_, was for a long time solved

only by methods which, in any hands but those of the greatest masters,

were very inartistic conventions. In the new art the concentration of

attention upon _form_, as a more important source of dramatic interest

and climax than _texture_, resulted in a neglect of polyphony which

seriously damaged even Gluck's work, and which always had the grave

inconvenience that while the new methods of blending and contrasting

instruments stimulated an increase in the variety, if not in the size of

orchestras, there was at the same time extreme difficulty in finding

occupation for the members of the lower middle class of the orchestra in

ordinary passages. On the other hand, it is significant how everything

in the development of new instruments seems to suggest, and be suggested

by, the new methods of expression. The invention of the damper-pedal in

the pianoforte epitomizes the difference between polyphony and symphonic

art, for it is the earliest device by which sounds are produced and

prolonged in a way contrary to the spirit of "real" part-writing. It is

possible to conceive of any number of notes struck and sustained by the

fingers as consisting of so many quasi-vocal parts; but when a series of

single sounds is played and each sound continues to vibrate by means of

a pedal which prevents the dampers from falling on the strings, then we

are conscious that the sounds have been produced as from one part, and

that they nevertheless combine to form a chord; and this is as remote

from the spirit of polyphonic part-writing as modern English is from

classical Greek.

The pianoforte trios of Haydn are perhaps the only works of first-rate

artistic importance in which there is no doubt that the earlier stages

of the new art do not admit of sufficient polyphony to give the

instruments fair play. Haydn finds the pianoforte so completely capable

of expressing his meaning that he is at a loss to find independent

material for any accompanying instruments; and the violoncello in his

trios has, except perhaps in four passages in the whole collection of

thirty-three works, not a note to play that is not already in the bass

of the pianoforte; while the melodies of the violin are, more often than

not, doubled in the treble. Yet there is a certain difference between

this and the work of a poor artist whose designs are threadbare. It

would be impossible to add a note to Haydn's trio; the only question is

how to account for the superfluity of much of the string parts and how

to make the trios effective in performance. It is sometimes suggested

that the 'cello part is best omitted and these works played as violin

sonatas. But experiment shows that in this condition much of the violin

part sounds incomplete; and the truth appears to be that Haydn is

thinking, like any modern composer, of the opposition of two solid

bodies of tone--the pianoforte and the stringed instruments. And it will

be found that the method of performance which most nearly justifies the

instrumental effect of these otherwise beautiful works is that in which

the pianoforte player regards himself as frequently doubling the

stringed instruments, and not vice versa. He should therefore in all

such passages play extremely lightly, so as to give the violin and

'cello the function of drawing the main outline. In the time of Bach

such writing was beautifully suited to enliven the dry glitter of the

harpsichord, and Bach's duets for clavier and violin seem to have been

sometimes played as trios with a violoncello playing from the clavier

bass. But this was ineffective with the pianoforte, and is only

explicable in Haydn as a survival. His trios were, indeed, published

under the title of "pianoforte sonatas with accompaniment of violin and

violoncello"; but this in no way militates against the above remarks as

to their proper method of performance nowadays, when we take into

consideration the greater strength of tone of the modern pianoforte,

especially in the bass, and the fact that in no case could a violinist

consent to play as an accompaniment such melodies as that at the

beginning of the G major trio known as No. 1.

For Mozart there never was any such _embarras de richesse_ in any

combination of instruments. His music is highly polyphonic, and modern

in its instrumental treatment throughout. It was lucky for the

development of instrumentation (as in all branches of music during the

change from polyphonic to formal design) that whenever the texture is

not polyphonic the natural place for melody is on the surface: in other

words, when the accompaniment is simple the tune is generally on the

top. Haydn, when he was not tempted by the resources of an instrument so

complete in itself as the pianoforte, soon learnt to write artistically

perfect string quartets in which the first violin, though overwhelmingly

the most important part, is nevertheless in perfect balance with the

other members of the scheme, inasmuch as they contribute exactly what

their pitch and the little polyphonic elaboration admissible by the

style will enable them to give. In the treatment of the orchestra

volumes might be written about Haydn's and Mozart's sense of fitness, as

shown in Haydn's experiments and Mozart's settled methods. Where they

consent to any practical custom from practical necessity they also

consent because it is artistically right for them, and if it had not

been artistically right they would have soon swept it away. For example,

it has often been said that the extent to which their orchestral viola

parts double the basses is due, partly to bad traditions of Italian

opera, and partly to the fact that viola players were, more often than

not, simply persons who had failed to play the violin. This was in many

cases true, and it is equally true that Mozart and Haydn often had no

scruple in following the customs of very bad composers. But, when we

look at the many passages in which the violas double the basses, we

shall do well to consider whether there is room in the harmonic scheme

for the violas to do anything else, and whether the effect would not be

thin without them. As music becomes more polyphonic the inner parts of

the orchestra become more and more emancipated. Already Mozart divides

his violas into two parts quite as often as he makes them play with the

basses. In Beethoven's orchestration there is almost always room for an

independent viola part. There is not room for one together with an

independent violoncello part; the wonderful use of muted solo

violoncellos in the slow movement of the _Pastoral Symphony_ being a

special effect, like the earlier instance in Haydn's 12th _Salomon

Symphony_. Otherwise, when Beethoven has anything special for the

violoncellos to say, he invariably softens and deepens their singularly

incisive cantabile tones by doubling them with the violas. In the

orchestras of his day this was perhaps the only safe proceeding for

players unaccustomed to such responsibilities, and that may have been

one of Beethoven's reasons for it. But it is equally certain that the

pure violoncello tone in large masses belongs to a distinctly different

region of orchestral effect. Haydn's numerous examples of independent

violoncello melodies are almost all either marked _solo_ or written for

such small orchestras that they would be played as solos.

Similar principles apply in infinite detail to the treatment of wind

instruments, and we must never lose sight of them in speculating as to

the reasons why the genius of Beethoven was able to carry

instrumentation into worlds of which Haydn and Mozart never dreamt, or

why, having gone so far, it left anything unexplored. A subject so vast

and so incapable of classification cannot be discussed here, but its

aesthetic principles may be illustrated by the extreme case of the

trumpets and horns, which in classical times had no scale except that of

the natural harmonic series. This could be fixed, within certain limits,

at whatever pitch suited the composition; but on the horn it could be

only very partially filled out by notes of a muffled quality produced by

inserting the hand into the bell of the instrument, a device impossible

on the trumpet. These instruments thus produced, in Haydn's and

Beethoven's times, a very remarkable but closely limited series of

effects, which, as Sir George Macfarren pointed out in the article

"Music" in the 9th edition of the _Encyclopaedia Britannica_, gave them

a peculiar character and function in strongly asserting the main notes

of the key. An instance of this characteristic function, specially

remarkable because the composer has taken exceptional measures for it,

is Beethoven's overture to _Fidelio_. It is in E major, while Beethoven

chooses to use trumpets in C. The only note which these can play in E

major is the tonic, to which they are accordingly confined until the

recapitulation of the second subject. This is unexpectedly placed in C

major, the remotest key reached in the overture, and one that had

already appeared in an impressive passage in the introduction which

foreshadows the reference in the first act to the hero in his dungeon

("Der kaum mehr lebt und wie ein Schatten schwebt"). In this key the

trumpets blaze out with an effect which entirely depends upon their

restricted part hitherto. On a sufficient acquaintance with the work

this would probably have revealed the essential nature of the instrument

to a hearer unacquainted with technicalities, and revealed it rather as

a characteristic than as a limitation. A still more remarkable instance

will be found in the third statement of the theme of the finale of the

9th symphony. When the trumpets take it up they make a remarkable change

at its 11th bar, for no other reason than that one of the notes, though

perfectly within their scale, and, indeed, already produced by them in

the very same bar, is so harmonized as to suggest the freedom of an

instrument with a complete scale. This passage shows that if Beethoven

had had the modern trumpet at his disposal, while he would no doubt

freely have used its resources, he would nevertheless have maintained

its character as an instrument founded on the natural scale, and would

have agreed with Brahms that the nobility and purity of its tone depends

upon its faithful adherence, at least within symphonic limits, to types

of melody suggestive of that scale.

This brings us to the latest radical change effected in instrumentation,

the change from symphonic to dramatic principles. It will be convenient

to take one supreme composer as the artist who has dealt so consistently

with the essentials of the new style that he may be conveniently

regarded as its creator. Even with this limitation the subject is too

vast for us to enter into details.

_Dramatic Instrumentation._--There is hardly one of Wagner's orchestral

innovations which is not inseparably connected with his adaptation of

music to the requirements of drama; and modern conductors, in treating

Wagner's orchestration, as the normal standard by which all previous and

contemporary music must be judged, are doing their best to found a

tradition which in another fifty years will be exploded as thoroughly as

the tradition of symphonic additional accompaniments is now exploded in

the performances of Bach and Handel. The main difference between

symphonic and modern dramatic orchestration depends on this: that in a

symphony any important incident will probably be heard again within five

minutes, in every circumstance of formal symmetry and preparation that

can attract the attention. This being so, it is absurd in a symphony to

use only such orchestral colours as would be fit for dramatic moments

which are not likely to recur for an hour or two, if they recur at all.

Such a passage as bars 5 to 8 in the first movement of Beethoven's 8th

symphony is as unintelligible from the point of view of Wagnerian opera

as the opening of the _Rheingold_ is unintelligible from the point of

view of symphony. But both are quite right. The modern Wagnerian

conductor is apt to complain that Beethoven, in his four-bar phrase,

drowns a melody which lies in the weakest register of the clarinet by a

crowd of superfluous notes in oboes, horns and flutes. The complainer

entirely overlooks the fact that this is the kind of music in which such

a phrase will certainly be heard again before we have time to forget it;

and as a matter of fact the strings promptly repeat it _fortissimo_ in a

position which nothing can overpower. A crowd of instruments that seemed

at first to overwhelm it in sympathetic comments is perfectly dramatic

and appropriate on the symphonic scale. On the operatic scale

established by Wagner such detail is simply lost. Far greater polyphonic

detail of another kind is no doubt possible, but it requires far longer

time for its expression. It cannot change so rapidly. It engages the ear

more exclusively, and therefore it needs an accuracy and an elaboration

of paraphernalia quite irrelevant to symphonic art. The accuracy and the

paraphernalia are equally exemplified in all Wagner's additions and

alterations of the classical orchestral scheme, for these all consist in

completing the families of instruments so that each timbre can be

presented pure in complete harmony. But the greatness of Wagner is shown

in the fact that with all the effect his additions have in

revolutionizing the resources of orchestration, he never regards his

novelties as substitutes for the natural principles of instrumental

effect. His brass instruments have lost nothing of their ancient

nobility. In his gigantic designs it inevitably happens that

instrumental resources are strained to their utmost, and there is,

perhaps, hardly anything which the makers and players of instruments can

be trained to do which is too remote to be demanded by some extreme

dramatic necessity in Wagner's scheme. But it is always some such

extreme necessity that demands it, and never an appetite too jaded for

natural resources. The crucial example of this is what Richard Strauss

has ingeniously called the "al fresco" treatment of instruments in large

orchestral masses (Berlioz-Strauss, _Instrumentationslehre_, edition

Peters). Experience shows that in the modern orchestra there is safety

in numbers, and that passages may with impunity be written for

thirty-two violins which no single player can execute clearly. Whether

this justifies Wagner's successors and imitators in showing a constant

preference for passages of which not even the general outline is

practicable; whether it justifies a state of things in which the normal

compass of every instrument in an advanced 20th-century score would

appear to be about a fifth higher than any player of that instrument

will admit; whether it proves that it is artistically desirable that

when there are eight horns in the orchestra their material should be

indistinguishable from pianoforte writing, and that, in short, the part

of every instrument should look exactly like the part of every

other--such questions are for posterity to decide. At present we can

only be certain that the criterion according to which Brahms, being a

symphonic writer, has no mastery of orchestration whatever, is not a

criterion compatible with any sense of symphonic style. It is therefore

not a criterion which can do justice to the principles of Wagner's

non-symphonic art, for its appreciation thereof is inevitably one-sided.

Least of all can it conduce to the formation of sound critical standards

for the new instrumentation which is now in process of development for

the future forms of instrumental music. These, we cannot doubt, will be

as profoundly influenced by Wagner as the sonata style was influenced by

Gluck.

Finally it must be remembered that musical euphony and emotional effect

are inseparable from considerations of harmony and polyphony. Timbre

itself is, as Helmholtz shows, a kind of harmony felt but not heard. Not

even the imagination and skill of Berlioz could galvanize into permanent

artistic life an instrumentation based exclusively upon instruments,

however suggestive his wonderful orchestral effects may have been to

contemporary and later artists, who realize that artistic effects must

proceed from artistic causes.

_Chamber-music_--The instrumentation of solo combinations is one of the

largest and most detailed subjects in the art of music. Something has

been said above as to its earlier aspects in the time of Haydn. Before

that time it was based exclusively on the use of the harpsichord either

as a means of supporting the other instruments or its also contributing

principal parts to the combination. Thus there were no string-quartets

before Haydn--at least none that can be distinguished from symphonies

for string-band.

Richard Strauss, in his edition of Berlioz's works on _Instrumentation_,

paradoxically characterizes the classical orchestral style as that which

was derived from chamber-music. Now it is true that in Haydn's early

days orchestras were small and generally private; and that the styles of

orchestral and chamber-music were not distinct; but surely nothing is

clearer than that the whole history of the rise of classical

chamber-music lies in its rapid differentiation from the coarse-grained

orchestral style with which it began. Orchestral wind-parts have been

discovered belonging to Haydn's string-quartet Op. 1, No. 5; his quartet

in D minor, Op. 9, No. 4, is already in a style which not even the most

casual listener could mistake for anything orchestral. On this

differentiation of styles rests the whole aesthetics of chamber-music;

but the subject is very subtle, and there is much, as for example in

Schubert's quartets and his C major quintet, that is inspired by

orchestral ideas without in the least vitiating the chamber-music style;

though, judged by its appearance on paper, it seems as unorthodox as the

notoriously orchestral beginnings of Mendelssohn's quartet in D and

quintet in B[flat]. The beginning of Mendelssohn's F minor quartet is,

again, a case usually, but perhaps wrongly, condemned for its

orchestral appearance on paper. Such matters cannot be decided off-hand

by the mere fact that _tremolos_ are characteristic of orchestras: the

question is whether in individual cases they have not a special

character when played by single players. Where this is so there need be

no confusion of style; but the danger of such confusion is great, and

with the rise of modern dramatic instrumentation it may be doubted

whether there are any standards of criticism in current use for

chamber-music of other than the sonata style. The development of

pianoforte technique since Beethoven has been in some ways even more

revolutionizing than that of the brass instruments; and pianoforte

instrumentation, both in solo and in chamber-music, is a study for a

lifetime.

_Orchestral Schemes Typical of Different Periods._

1. _16th Century._--We, with our stereotyped modern notions of the

grouping of voices, may get some idea of the freedom of the

16th-century composers' imagination by noting that the four-part

movements for semi-chorus or solo voices in Palestrina's Masses

present us with no fewer than seventeen different combinations of

voices, and that of these the familiar group of soprano, alto, tenor

and bass is not the most common, though it is invariable as that used

for entire four-part Masses. In three-part movements Palestrina

presents us with twelve combinations of voices. In his five-part

Masses and single movements we find eight combinations, and his

six-part Masses and single movements show eleven. And when he writes

in eight parts for a double chorus the two groups are seldom

identical.

2. _18th Century._--17th-century instrumentation may be neglected here

as having begun in chaos and ended in the schemes of the 18th-century

decorative instrumentation. The following is Bach's fullest orchestra:

the string-band, consisting (as at the present day) of violins in two

parts, violas, violoncellos, doubled (where the contrary is not

indicated) by double basses; the wind instruments (generally one to

each part, as the string-band was never large)--2 flutes, 2 or 3

oboes, or _oboe d' amore_ (a lower-pitched and gentler type), _taille_

or _oboe da caccia_ (some kind of alto oboe corresponding to the cor

anglais), bassoon, generally doubling the string basses, 2 horns, with

parts needing much greater practice in high notes than is customary

to-day, 3 (occasionally 4) trumpets, of which at least the first 2

were played by players especially trained to produce much higher notes

than are compatible with the power to produce the lower notes (the

high players were called _Clarin-Blaser_; and the others

_Principal-Blaser_); a pair of kettle-drums, tuned to the tonic and

dominant of the piece.

Handel's orchestra is less detailed. He does not seem to have found

any English trumpeters capable of playing as high parts as those of

the German _Clarin-Blaser_, and his plan seems generally to get as

many oboes and bassoons as could be procured to double the top and

bottom of his string-band. But his definite orchestral effects in

certain places (e.g. "He led them forth like sheep," in _Israel in

Egypt_, and the music of the _Witch of Endor_, and the appearance of

Samuel's spirit in Saul) are as modern as Gluck's.

3. _Symphonic Orchestration._--Mozart's full symphonic scheme requires

the string-band, 1 flute (rarely 2), 2 oboes, 2 clarinets (whenever he

could obtain them, he being the first composer who really appreciated

them, instead of regarding them either as cheap substitutes for the

_clarino_ or high trumpet of Bach, or, like Gluck and, with rare and

late exceptions, Haydn, as merely adding to the force of _tutti_

passages). Further, 2 horns, 2 bassoons, 2 trumpets and a pair of

kettle-drums.

Mozart imports from church music 3 trombones for special passages in

his operas.

Beethoven almost always has 2 flutes, and invariably 2 clarinets. In

his 5th symphony he introduced 3 trombones and extended both the upper

and lower extremes of the wind-band by a piccolo and a double bassoon.

"Turkish music," i.e. the big drum, cymbals and triangle, was used by

Haydn in his _Military Symphony_, and Mozart in his _Entfuhrung_, for

reasons of "local colour"; it appears as an extreme means of climax in

the finale of Beethoven's 9th symphony.

4. _Wagner's Orchestra: Tristan und Isolde._--(Families of instruments

are connected by a brace.)

Strings: as usual, but subject to minutely complex grouping.

3 flutes (3rd to play piccolo when required).

/ 2 oboes.

| 1 cor anglais.

| 3 bassoons.

| 2 clarinets.

\ 1 bass clarinet.

4 horns. (The mechanical improvements by which horns and

trumpets acquired a complete scale have revolutionized the

nature of those instruments; and Wagner's orchestration, more

than that of any other composer, has profited by this. Yet, in

the preface to the score Wagner speaks very strongly of the

loss of the original character of the horn in the hands of

ordinary players; and goes so far as to say that, if experience

had not shown that they could be trained to play _nearly_ as

smoothly as the classical players, he would have renounced all

the advantages of the new mechanism.)

3 trumpets.

3 trombones.

1 tuba.

2 or, for safety in tuning, 3 kettle-drums.

Triangle and cymbals.

1 harp (multiplied _quant. suf._).

In _Der Ring des Nibelungen_ Wagner specifies the proportions of the

string-band as 16 first and 16 second violins, 12 violas, 12

violoncellos, 8 double basses. The rest of the orchestra consists of--

Piccolo and 3 flutes.

/ 3 oboes and cor anglais, or 4th oboe.

\ 3 bassoons, or 2 and contra-fagotto.

3 clarinets and 1 bass clarinet.

8 horns, 4 of whom are also required to play 4 specially

constructed tenor and bass tubas.

1 ordinary (double-bass) tuba.

/ 3 trumpets.

\ 1 bass trumpet. (A project of Wagner's which

instrument-makers found impracticable, so that Wagner had to

content himself with a kind of valve trombone shaped like a

trumpet.)

3 trombones and 1 double-bass trombone.

2 pairs of kettle-drums.

/ Triangle.

| Cymbals.

| Big drum.

\ Gong.

6 harps.

5. _Chamber-music._--Bach's and his contemporaries' combinations with

the harpsichord show the natural fondness, in his day, for instruments

of a tone too gentle for prominent use in large rooms, or indeed for

survival in modern times. Thus there was quite as much important solo

music for the flute as for the violin; and almost more music for the

viola da gamba than for the violoncello. A frequent combination was

flute, violin and harpsichord (very probably with a violoncello

doubling the bass), and in more than one case the violin was partly

tuned lower to soften its tone.

Classical and modern chamber-music in the sonata style consists mainly

of string-quartets for 2 violins, viola and violoncello; string-trios

(rare, because very difficult to write sonorously); pianoforte-trios

(pianoforte, violin and violoncello); pianoforte-quartets (pianoforte

with string-trio); pianoforte-quintets (pianoforte with

string-quartet); string-quintets (with 2 violas, very rarely with 2

violoncellos), and (in two important cases by Brahms) string-sextets.

Larger combinations, being semi-orchestral, especially where the

double-bass and wind instruments are used, lend themselves to a

somewhat lighter style; thus Beethoven's septet and Schubert's octet

are both in the nature of a very large serenade.

Wind instruments produce very special effects in chamber-music, and

need an exceedingly adroit technique on the part of the composer.

Magnificent examples are Mozart's trio for pianoforte, clarinet and

viola, his quintet for pianoforte, oboe, clarinet, horn and bassoon

(imitated by Beethoven), his quintet for clarinet and strings,

Brahms's clarinet-quintet for the same combination, and his trio for

pianoforte, violin and horn. (D. F. T.)

INSTRUMENT OF GOVERNMENT, the name given to the decree, or written

constitution, under which Oliver Cromwell as "lord protector of the

commonwealth" governed England, Scotland and Ireland from December 1653

to May 1657.

The Long Parliament was expelled in April 1653 and the council of state

dissolved; the Little, or Nominated, parliament which followed ended its

existence by abdication; and Cromwell, officially lord general of the

army, with a new council of state, remained the only recognized

authority in the country. It was in these circumstances that the

Instrument of Government, drawn up by some officers in the army,

prominent among whom was John Lambert, was brought forward. The document

appears to have been under consideration since the middle of October

1653, but Ludlow says it was "in a clandestine manner carried on and

huddled up by two or three persons," a remark probably very near the

truth. The nominated parliament abdicated on the 12th of December 1653,

and after certain emendations the Instrument was accepted by Cromwell on

the 16th. Consisting of forty-two articles, the Instrument placed the

legislative power in the hands of "one person, and the people assembled

in parliament"; the executive power was left to the lord protector,

whose office was to be elective and not hereditary, and a council of

state numbering from thirteen to twenty-one members. The councillors

were appointed for life; fifteen were named in the Instrument itself;

and Cromwell and the council were empowered to add six. To fill

vacancies parliament must name six persons, of whom the council would

select two, the choice between these two being left to the protector. A

parliament was to meet on the 3rd of September 1654, and until that date

the protector with the consent of the council could make ordinances

which would have the force of laws. After the meeting of parliament,

however, he had no power of legislation, nor had he any veto upon its

acts, the utmost he could do being to delay new legislation for twenty

days. A new parliament must be called "once in every third year,"

elaborate arrangements being made to prevent any failure in this

respect, and for five months it could not be dissolved save with its own

consent. The parliament, composed of a single chamber, was to consist of

460 members--400 for England and Wales, and 30 each for Scotland and

Ireland--and the representative system was entirely remodelled, growing

towns sending members for the first time, and many small boroughs being

disfranchised. A large majority of the English members, 265 out of 400,

were to be elected by the counties, where voters must possess land or

personal property of the value of L200, while in the boroughs the

franchise remained unaltered. In Scotland and Ireland the arrangement of

the representation was left to the protector and the council. Roman

Catholics and all concerned in the Irish rebellion were permanently

disfranchised and declared incapable of sitting in parliament, and those

who had taken part in the war against the parliament were condemned to a

similar disability during the first four parliaments. The protector was

empowered to raise a revenue of L200,000 in addition to a sum sufficient

to maintain the navy and an army of 30,000 men, and religious liberty

was granted "provided this liberty be not extended to Popery or

Prelacy." The chief officers of state were to be chosen with the consent

of parliament, and a parliament must be summoned at once in case of war.

The practical effect of the Instrument was to entrust the government of

the three countries to the parliament for five months out of every three

years, and to the protector and the council for the remainder of the

time. Although the Instrument bristled with possibilities of difference

between parliament and protector, "it is impossible," as Gardiner says,

"not to be struck with the ability of its framers."

Having issued many ordinances and governed in accordance with the terms

of the Instrument, Cromwell duly met parliament on the 3rd of September,

and on the following day he urged the members to give it the force of a

parliamentary enactment. Many representatives objected to the provision

placing the supreme power in the hands of a single person and of

parliament, a discussion which was futile, as clause XII. of the

Instrument declared that "the persons elected shall not have power to

alter the government as it is hereby settled in one single person and a

parliament." The proceedings were soon stopped by Cromwell, who on the

12th of September explained that there was a difference between

"fundamentals" which they might not, and "circumstantials" which they

might, alter. He concluded by stating that they would be excluded unless

they subscribed a recognition to be true to the protector and the

commonwealth, and to respect the terms of clause XII. Over three hundred

members took the required step; but they proceeded to alter the

Instrument in other ways, and over the question of the control of the

army they were soon in sharp conflict with the protector. At length, on

the 22nd of January 1655, Cromwell, counting twenty weeks as five

months, dissolved parliament.

Regarding the Instrument as still in force the protector sought for a

time to rule in accordance with its provisions; but new difficulties and

growing discontent forced him to govern in a more arbitrary fashion.

However, in July 1656 he issued writs for a second parliament which met

in the following September. Many members, men of advanced views, were

excluded by the council of state, acting on the strength of clause

XVII., which declared that those elected must be "persons of known

integrity, fearing God, and of good conversation." The remainder

discussed the question of the future government of the country, and in

May 1657 Cromwell assented to the Humble Petition and Advice, which

supplanted the Instrument of Government. Gardiner says the Instrument

was "the first of hundreds of written constitutions which have since

spread over the world, of which the American is the most conspicuous

example, in which a barrier is set up against the entire predominance of

any one set of official persons, by attributing strictly limited

functions to each."

The text of the Instrument is printed in S. R. Gardiner's

_Constitutional Documents of the Puritan Revolution_ (Oxford, 1899).

Protectorate_, vols. ii. and iii. (London, 1897-1901); L. von Ranke,

Letters and Speeches_ (London, 1897-1901). (A. W. H.*)

INSUBRES ([Greek: Isombres, Insoubroi]), a Celtic people of upper Italy,

the most powerful in Gallia Transpadana, inhabiting the country between

the Adda, the Ticinus and the Alps. According to Livy (v. 34) they

appear to have been a branch of the Aedui in Gallia Transalpina, though

others assume that they were Umbrians, a view to some extent supported

by the form Is-ombr-es. Livy states that Bellovesus and his Gauls,

having crossed the Alps and defeated the Etruscans near the Ticinus,

found themselves in the territory of the Insubres (also the name of a

_pagus_ of the Aedui). Here they built a city and called it Mediolanum

(Milan), after the name of a village in their home in Gallia

Transalpina. The name Insubres thus appears applied to the inhabitants

(1) of the Aeduan _pagus_, (2) of the territory in Gallia Transpadana

occupied by Bellovesus, (3) to the founders of Mediolanum. From 222 to

195 B.C. the Insubres were frequently at war with the Romans. In 222

they were defeated at Clastidium by M. Claudius Marcellus, who gained

the _spolia opima_ by slaying with his own hand their king Viridomarus

(Virdumarus), and in 194 they were finally subdued by L. Valerius

Flaccus.

See H. Nissen, _Italische Landeskunde_ (1902) ii. 179; A. Holder,

_Altkeltischer Sprachschatz_, ii. (1904).

INSURANCE, a term meaning generally "making oneself safe against"

something, but specially used in connexion with making financial

provision against certain risks in the business of life. The terms

Assurance and Insurance are in ordinary usage synonymous, but in the

profession "assurance" is confined to the "life" business, and

"insurance" to fire, marine and other miscellaneous risks. Assurance was

the earlier term, and was used of all forms of insurance

indiscriminately till the end of the 16th century. Insurance--in its

earlier form, "ensurance"--was first applied to fire risks (see note

_s.v._ "Insurance" in the _New English Dictionary_).
