Among the suites which do not belong to these collections, we

recollect with great pleasure the dainty dances and intermezzi--for

example in the E flat major suite, and especially that in B minor

with overture in French style (Largo--Fuga--Largo) which appeared in

the second part of the Klavierübung as a piece for two manuals. It

presents, among the many intermezzi, a gavotte in the style of the

orchestral Partiten, which links itself with the choicest dances, in

graceful style, of the preceding century. From the clavier-suites we

pass to the clavier-sonatas, which, still in the style of Italian

art, mingled with dances, offer free combinations of different

movements. The melodious andante of the D minor sonata, and its

final allegro-movement rattling off almost in one part, are perfect

pearls. A step further we reach the fantasias with fugues; especially

the polyphonic one in A minor, the recitatival “Chromatische” and

the concerto-like C minor, fugally treated, but still not a fugue.

These three fantasia-pieces were Bach’s direct bequests to the

future. In the polyphony of the brilliantly rushing fantasia in A

minor, rising with endlessly delicate melody, we are reminded of the

“Meistersinger”; in the chromatic fantasia, with its broad narration

and grandiose concluding pedal point, the clavier seems to us to speak

with the freedom of a drama; in the significantly constructed C minor

fantasia rests the whole formal talent of the instrumental composers

of the expiring eighteenth century.

The three “brilliant” fantasias incline naturally to the concerto

style, which partly abandoned counterpoint in favour of a mere

accompaniment, and partly subordinated it to the careful elaboration

of a single voice-part. The problem of committing a whole concerto

to the clavier alone, Bach has solved in his famous “Italian

Concerto”--Italian in the conception of the style of execution

proper to concertos, which in Italy developed itself specially on

the violin--Italian in the form of a slow movement enclosed by two

quicker movements, which had emerged as the most practical method

for the violin (half in rivalry with the Tutti, half in the interest

of solo virtuosity). Bach has in the Italian concerto perfectly

attained the object of writing in several movements a clavier piece

fit for execution. The grand sonatas of a later time have been able

to add nothing essential to it. The first movement is an ingenious

combination of pregnant motives, which reminds us of tutti-effects,

of running semiquaver figures, and melodious passages on moving

quaver accompaniment, which correspond to the second lyrical theme

of sonatas. The slow movement is a great recitative song with a

berceuse-like accompaniment, of a structure so delicate that we are

irresistibly reminded of the contours of old primitive pictures.

It has the dainty grace of archaic outline, just like that in the

two-part interwoven arioso[80] of the B minor Prelude, or in the crisp

melody of the E flat Prelude (Wohltemperiertes Klavier I.). The third

movement, which is quicker, unravels the whole into the cheerful

linked play of floating parts, unsurpassed in elegant construction by

any of the great formalists. Floating passages run up and down among

chords, falling like drops of rain, and the voices combine in pleasant

unity.

Wohltemperiertes Klavier. In the Royal Musikbibliothek, Berlin.]

The entire multiformity of music at the beginning of the eighteenth

century is expressed in the clavier-works of Bach. As yet the

sonata-form with its two themes, and its “free” section in the middle

of the movement, has not become the consecrated scheme;[81] and

all the forces which had gradually worked towards this form exert

themselves unfettered, in order to make themselves effective now in

this, now in that combination of movements and parts of movements.

“Thematic” is not neglected. To a series of suite-movements similar

commencing motives are given, and the motives of earlier parts are

taken up in the later. But this tendency to unity does not act as

a restraint upon form, and does not reduce everything to one stiff

mould. There is a fugue with a prelude, by Bach, that in E flat major

(Wohltemp. Kl. i.), which offers perhaps the most delicate example of

this unrestrained unity of motive. The Prelude, which is much longer

than the fugue, begins with semiquaver figures, whose characteristic

is melodious sustained passages advancing by sixths and sevenths;

after this introduction, begins in toccata-fashion a kind of slow

fugue, which unfolds the just heard motive in a terser form; and

finally, in a third part, mingles itself with the former semiquaver

figure. The fourth part is so to speak moulded in the fugue form,

which in its “subject” makes use of the characteristic leap of a

seventh, found in the Prelude, as a main feature, and brings the play

to a conclusion in a busy and lively manner. The relations of motive

are only to be _felt_, not seen; but they are _there_, and give to

the formal freedom of this piece a vigour of its own. Thus, in many

of Bach’s pieces, apart from the direct thematic motives, we shall

find this indirect assonance, which, springing from a general feeling

of unity, is, in fact, a more dainty framework for the piece than any

unity that could be impressed on it from outside.

So also is it with the construction of the pieces. We find everywhere

traces of the later sonata-style; and not less in the dance-forms

than in free movements. It was too natural to repeat the beginning of

the piece at the end, then to transpose a second theme into the main

key, and in the centre to work out the main motive in a kind of free

fantasia. But so long as the author held fast to the binary form of

the piece, and to the Da capo of each half, as was the case at this

time, so long did the parts of the “developments” and repetitions fail

to concentrate themselves so completely as not to leave a rich field

of varied forms in which fancy could move at ease. Bach’s imagination

was keen enough to give to every one of these forms, as they developed

themselves each moment, a natural and elemental strength. A toccata by

him, although they are all very various in form, or a fantasia, like

the C minor, which is of sonata-character, is built up so firmly and

self-evidently that the later uniformity of the sonata seems rather to

betray a weakening than a strengthening of style.

[That the severe forms of Prelude and Fugue are abundantly capable of

expressing poetical ideas is easily shown. Turn only to the D minor

Prelude and Fugue in the second part of the Wohltemperiertes Klavier.

Although the casual reader perceives in the one movement merely an

exercise in two parts, in the other, one in three parts, it requires

only a slight exercise of imagination to see that the work really

pictures some such feelings as the following: In the Prelude, a man

suddenly realises himself in the true “out-of-doors” of this life,

with the rain and hail of difficulties and troubles sensibly battering

him. Bravely, but ineffectually, he tries to push through the tempest,

and sinks wearily into half-sleep, is awakened by a renewed riot of

the elements around, tries harder than before, and longer too, to

impress himself on his circumstances, and be master of things, and

succeeds in a sorrowful kind of way, for the storm passes, sighs

itself out, and he at last can rest. In the Fugue, he tries to begin

his work in the world. His efforts are strong in their intention, but

die down as weakly as the devil himself could wish, one after another.

But though these messengers of his will return to him empty again and

again, he still goes on. “It is the best I can do, and something may

come of it in the end,” he seems to say. And there is in the final

bars, where the subject occurs for the last time, a certain expression

of savage pleasure at the thought of not having given in, mingled with

the abiding knowledge of an abundant measure of continual failure,

such as is no imagination to any man who cares about his work, and has

arrived at the sorrowful conviction that most of his walking must be

done in the dark.][82]

Perhaps the Bach Preludes show this freedom on the most liberal scale.

For the Prelude is not so much a kind of form, like the Toccata, but

a mere Piece before a Piece; it lays down the lines to be followed,

but in itself is uncertain, unfixed in form. The Prelude may be a

Toccata or a Sonata, a Symphony or an Invention; it can let its upper

part, in arioso style, wander over the continuo, or it may burst forth

in fullest polyphony. It may have the rhythm and regularity of beat

of the dances, or may speak with the freedom of recitative without

thought of a repetition. The abundance of possibilities which Bach

found at his disposal in the working out of themes, construction,

and style, are mirrored in the Preludes, from the real fugue to the

playful method of the court-musicians.[83] Anyone who undertakes

the pleasant task of simply running through the Preludes of the

“Wohltemperiertes Klavier” (vol. ii.), will be able to appreciate

the full spring-like freshness in which the free music of this time,

so rich in promise for the future, lived out its life. And, like the

discriminating observer of nature, he will admire, in just these yet

unspoilt forms, the great harmony and natural unity which is exhibited

by the young life of the creation. The Prelude in E major will always

seem to me a blossom of this spring-time (“Wohlt. Kl.” i.)--one of

the daintiest pieces ever written for the clavier. In an easy 12/8

time the poem begins with an allegretto theme, ingeniously invented,

and playful in style. It is supported by two voices; but they soon

take part canonically in the delightful movement. We have, in the

play of cheerful thought, come to the dominant of the dominant[84]

(F sharp), and from this F sharp we rest, in a humorous change, a

moment on D, and even G, till, just as rapidly, we emerge through

a chromatic maze at B natural once more (Bar 8). The repose of the

succeeding dominant passage is gently stirred by ravishing transient

modulations, on which the very spirit of happiness seems to rest. A

beautiful chain of syncopations leads us through F sharp minor, and a

jubilant run of semiquavers, built on a dominant chord on E, brings us

to the recapitulation of the opening subject in the key of A (Bar 15),

starting from which the movement repeats itself accurately (for eight

bars) in its eternal cheerfulness, the piece closing with a couple

of bars in Schumann’s ingenious manner, still sweetly suggesting the

spring-song of its earlier strains.

We find, then, that nothing essentially new in “form” has been used

by later artists, of which the germ did not already exist in Bach.

Nay, even in programme-music (supposed by many to be an invention of

modern times) for the clavier, which Kuhnau so quaintly worked out

in his Biblical Stories,[85] Bach has entered the field in a youthful

composition. He is singing the departure of his brother. The first

adagio movement in anapæstic rhythms represents the flattery of the

friends, who are trying to dissuade the traveller from his journey. It

is time for the fugue, and this is the picture of various misfortunes

which may befall him in foreign parts. A mournful arioso passage on

a ground bass,[86] chromatic in character, is a universal lament

of his friends. In a full-chorded Intermezzo they come and bid him

good-bye, seeing that it cannot be otherwise. Now the postillion sings

his air, broken with octave passages, representing the smacks of his

whip; and since a fugue is the end of all good things, we hear one in

four parts raise itself above the post-horn, with whip episodes to

increase the realism. The young Bach did not go as far as Frohberger,

who represented the assaults of robbers, crossings of the Rhine, and

even forcible ejectments with violence, on the clavier; or as Kuhnau,

who had given the cheating of Laban in “deceptive” cadences,[87] and

Hezekiah’s doubtings in the rehearsal of a choral; yet this kind of

programme-music declined in the eighteenth century precisely as it has

grown up again in the nineteenth.

If we believe Spitta, Bach also left behind him one of those

anagram-pieces which were so in the taste of his time--the fugue

on the letters B A C H. But the composition seems too leathern and

insipid for us to be able to express a decided opinion. There is in

literary criticism a well-known false method--the wish utterly to deny

insipidity to the great. But since Bach’s authorship of the “B A C H”

fugue is not vouched for, and since he never elsewhere put together

so many dull pages, we are not compelled to load his memory with its

weight.

[Illustration: John Mattheson, at the age of 37.]

As we find in Bach the possibilities of all the great forms of the

succeeding centuries, so we find in him also all the germs of future

expression, rhythm, harmony, and melody. Nothing is more perverse than

to regard this music as academic and expressionless. Expression is

never absent from counterpoint except when it sacrifices impressionism

to the mere display of technical mastery. We shall even to-day seek

in vain for piano compositions more full of expression than some

of the preludes contained in the Wohltemperiertes Klavier. In the

remarkably decadent C sharp minor, in the B minor, so full of gentle

mournfulness, in the E flat minor with its grandiose solemnity, in

the B flat minor with its organ-like seriousness, or in the F major

with its Meister-singer melody[88] (in Part II. Wohlt. Kl.), there

is an unsurpassed depth of expression. Nowhere is there a greater

variety of characters than would be presented by a comparison of the

fugal themes in this work. Merely to turn over a few of its pages is

to see before us an abundance of content which no other music-book

would easily conceal in so narrow a space. It is in the service of

expression that the motives for the architecture of the fugues are

unfolded; in the service of expression the rhythms are developed,

whose skilful planning is only clearly seen in a piece like the G

major Prelude (Wohlt. Kl. i.); in the service of expression are formed

the harmonies, from their simple successions, as in the C major

Prelude (W. Kl. i.) or of the C sharp major Prelude (W. Kl. ii.)

to the complicated retardations and tied notes of the B flat minor

Prelude (Wohl. Kl. i.), or in the B minor fugue (W. Kl. i.) on a theme

so wonderfully sad that no bolder chords can be found in the days of

the most furious chords of the seventh. In Bach, says Marpurg, the

different talents of a hundred other musicians were united.

Bach played very quietly. In his time technique began to change its

principles. The hand was no longer to be held out flat, but curved, so

as to provide a series of hammers rather than levers. The passing of

the fingers over each other, as practised by Mattheson, a player of

distinction almost equal to Bach and Handel, gave way to a systematic

_under_-passing; and the thumb, which Bach had seen applied by former

generations only to wide stretches, began its important part as the

“linking” finger. The remains of Bach’s finger-exercises, and the

directions which stand in the lesson-book of his son Philip Emanuel,

have been usefully compared[89] by Spitta, who has drawn a picture

of the technique of John Sebastian, which in its grandeur well fits

with his work. “It was a system of under-moving fingers, worked out by

unparalleled practice and talent, applying not merely to the thumb

but to the middle fingers, and usually so arranged that only a longer

finger can pass over a shorter.[90] This produced a technique which,

like Bach’s work, united past and future in one classic method. Our

thumb-technique, which in essentials goes back to Philip Emanuel, is a

mere fragment of Bach’s method, just as the whole succeeding art was,

compared with Bach, but a fragment on a large scale.” But it is hard

to be clear on these matters. Before the time of “schools” technique

was a matter of personality; and reconstruction to us of a later age

is utterly out of the question.

Should a diligent scholar try to reconstruct from Bach’s pieces his

technique, so far as it had influenced musical form, he would soon be

brought to a pause. For when we examine this literature, we see that

to the master everything was possible, and that he never gave form

to a conception for the sake of technique. He is a stupendous genius

who does not write for everybody, and therefore his compositions are

often difficult; but the difficulties are never against the genius of

the clavier, and can be conquered by anything but idleness. He has,

again, written some taking show-pieces, like the Prelude and Fugues

in A minor (Steingräber, vii. 29), which, as “paying” salon pieces,

sound much harder than they are; and, alongside of these again, are

pieces which spring from the very joy in the abundance of possible

techniques and of new conceptions. To this class belongs, if genuine,

the Fantasia in A minor (Steingräber, vii. 8), in which pure technical

fireworks are let off, of short scale passages for both hands,

swinging chords and octaves, running motives with astonishing passage

effects, passages of sixths with over and under accompaniments, and

melodious phrases with embellishing harmonies. But here the first rank

is taken by the famous “Goldberg” variations, already printed by Bach,

partly set for two manuals, an album of thirty technical conceptions,

in which everything possible in tone-material is contained, from

arioso to canon, from _grave_ to _presto_; everything, in fact, which

Bach ever adopted for the setting of his ideas. The twenty-ninth

variation, which can also be played on one manual, brings before us

chords and passages of interwoven beauty which prepare beforehand the

way for Liszt. Even in technique, then, the genius of Bach stretches

over centuries.

It cannot be exactly maintained that Bach treated the clavier wholly

individually, but he nevertheless has helped to individualise it.

At the beginning of last century, when the clavier was still for

the most part an accompanying instrument, when it sustained in the

orchestra the foundation-harmonies, even if at the same time another

clavier entered in concerto-wise, genius itself could not release the

instrument from this corporate conception without running against

the whole spirit of the time. It is remarkable how Bach left it the

character of a thorough-bass instrument, and yet allowed it so much

independence. It has at one time the divided nature of the unifying

organ, as organ-pieces were then regarded still as practically ready

for the clavier; at another the pizzicato and running character of

the lute. Bach could entitle his formally interesting E flat major

piece, Prelude, Fugue, and Allegro (Steingräber, vii. 30) as Prélude

pour le luth _ò çembal_.[91] From the traditions of the lute and organ

the peculiar nature of the clavier comes into existence, and it was

in the maintenance of the _via media_ between these less delicately

expressive extremes that its future lay. How _individually_ Bach

regarded the clavier is seen in the pieces in which it is combined

with flute and viol da gamba or violin, or in the concertos with

one, two, three, or even four claviers. Among these the C major and

D minor concertos with three claviers, now combined, now isolated,

represent the highest points of this older form of the concerto, as

yet not adapted for solo-virtuosity. But yet plainer is his insight

in the direct transcriptions which he has made of violin pieces for

the clavier. He interpolates in the freest fashion middle voices,

which are kept together by “pedals;” ornamentations which draw out

the air of the melody in clavier-style; or rapid vibrating over-parts

which make up for the loss of the long-drawn violin tones. And by

this insight into the peculiar character of the clavier, he makes

it more capable not only of speaking with its own voice, but also

of spreading over wider circles the literature of other instruments

by means of suitable and self-intelligible transcriptions. Bach’s

extreme love of this instrument, which so often gave him the means of

expression for his musical conceptions, contributed not the least to

such an interpretative mission. Slowly the world accustomed itself to

understand music, not _per chorum_, but _per instrumentum_.

It is at this point that the great need is felt. A mechanical advance

is required to bring the expressive capacity of the clavier into a

line with the demands of genius upon it. The rivalry between the

clavicymbal and the clavichord[92] was not yet quite decided. In

Romance lands the former was the favourite; in Germany the latter.

On the former great effects could be better produced; on the latter

the more soulful tone, and the unique embellishment called “Bebung.”

Bach wrote much, including the Wohltemperiertes Klavier, for the

clavichord, which even his son Philip Emanuel still preferred to

the clavicymbal. But he was so unable to disguise from himself the

counter advantages of the fuller and broader quill-instrument, that

he published pieces for “Kiel-flügel”[93], with two manuals and

registers for forte and piano. These registers were the only means

for giving light and shade to the monotonous note of the “cymbal”;

to give light and shade by turns, as in the organ, so that on the

upper manual a melody could be played loud, and on the lower the

accompaniment could be played soft. In Kuhnau we see the forte and

piano, which he aimed at by simply striking on the clavichord, used

as a means of expression. In the Biblical Stories Jacob has just

been cheated by Laban, in receiving Leah for Rachel. “The bridegroom

is contented,” as a minuet shows us; but “his heart prophesies

misfortune,” and the measure rushes on, becomes piano and più-piano;

suddenly Jacob takes heart again--forte; after a bar or two he goes to

sleep--piano; he wakes--forte; falls into deep slumber--piano. In his

“Italian Concerto” Bach had made a much more specialised use of this

by the register. He had mingled loud and soft parts, and each hand

alternately is marked forte or piano. In these, and similarly in the

echo-movement of the suite with “Ouverture à la manière française,”

we are led to think of a splendid clavicymbal, such as the one

preserved ostensibly as Bach’s in the Berlin Museum of Instruments.

In that, every one of the combinations of four strings can be altered

by pulling a register: the manuals admit of coupling, and a soft

lute-stop is provided.

We know of a hundred attempts to improve the sound of the clavier,

and make it more expressive. Here, too, the eighteenth century is the

experimental preparation for the happy successes of the nineteenth.

Now the string-choruses were tuned in octaves, now pedals were added

for low notes, now the sound-boards were strengthened, now the lower

strings were made of copper, and the higher of steel; and throughout

a rich experience was acquired as to the best way of constructing the

separate parts. Leather plectrums appear everywhere in order to make

the tone softer and less metallic. The clavier, in fact, was made to

imitate all possible orchestral instruments, and even such natural

phenomena as thunder and lightning, by means of register-stops. Or,

the forte and piano stops were combined, ever more artistically, into

as many as two hundred and fifty permutations, so that an endless

number of shades was possible.
