FIG. 5.--Bass Flute. Brussels Museum.]

The bass flute cited by Mersenne should not differ much from that of

the Museo Civico at Verona. We suppose it to have been in [notes], and

that it was furnished with an open key like that which was applied to

the recorders (_flutes douces_) of the same epoch, the function of the

key being to augment by another note the compass of the instrument in

the lower part. A bass flute in G similar to the one in fig. 5 is

figured and described in Diderot and D'Alembert's encyclopaedia [27]

(1751). According to Quantz,[28] it was in France and about the middle

of the 17th century that the first modifications were introduced in

the manufacture of the flute. The improvements at this period

consisted of the abandonment of the cylindrical bore in favour of a

conical one, with the base of the cone forming the head of the

instrument. At the same time the flute was made of three separate

pieces called head, body, and tail or foot, which were ultimately

further subdivided. The body or middle joint was divided into two

pieces, so that the instrument could be tuned to the different pitches

then in use by a replacement with longer or shorter pieces. It was

probably about 1677, when Lully introduced the German flute into the

opera, that recourse was had for the first time to keys, and that the

key of D# was applied to the lower part of the instrument.[29] The

engraving of B. Picart, dated 1707, given in Hotteterre's book,

represents the flute as having reached the stage of improvement of

which we have just spoken. In 1726 Quantz,[30] finding himself in

Paris, had a second key applied to the flute, placed nearly at the

same height as the first, that of the [notes], intended to

differentiate the D# and the E[flat].[31] This innovation was

generally well received in Germany, but does not appear to have met

with corresponding success in other countries. In France and England

manufacturers adopted it but rarely; in Italy it was declared

useless.[32] About the same time flutes were constructed with the

lower extremity lengthened sufficiently to produce the fundamental C,

and furnished with a supplementary key to produce the C[sharp]. This

innovation, spoken of by Quantz,[33] did not meet with a very

favourable reception, and was shortly afterwards abandoned. Passing

mention may be made of the drawing of a flute with a C key in the

_Music-Saal_ of J.F.B. Majer (Nuremberg, 1741), p. 45.

The tuning of the instrument to different pitches was effected by

changes in the length, and notably by substituting a longer or shorter

upper piece in the middle joint. So wide were the differences in the

pitches then in use that seven such pieces for the upper portion of it

were deemed necessary. The relative proportions between the different

parts of the instrument being altered by these modifications in the

length, it was conceived that the just relation could be

re-established by dividing the foot into two pieces, below the key.

These two pieces were adjusted by means of a tenon, and it was

asserted that, in this way, the foot could be lengthened

proportionately to the length of the middle joint. Flutes thus

improved took the name of "flutes a registre." The register system

was, about 1752, applied by Quantz to the head joint[34] and, the

embouchure section being thus capable of elongation, it was allowable

to the performer, according to the opinion of this professor, to lower

the pitch of the flute a semitone, without having recourse to other

lengthening pieces, and without disturbing the accuracy of intonation.

The upper extremity of the flute, beyond the embouchure orifice, is

closed by means of a cork stopper. On the position of this cork

depends, in a great measure, the accurate tuning of the flute. It is

in its right place when the accompanying octaves [notes] are true.

Quantz, in speaking of this accessory, mentions the use of a nut-screw

to give the required position to the cork.[35] He does not name the

inventor of this appliance, but, according to Tromlitz,[36] the

improvement was due to Quantz himself. The invention goes back to

1726.

When the _Method_ of Quantz appeared there were still in use, besides

the orchestral flute in D, the little fourth flute in G, the low

fourth flute in A, and the flute d'amour a note higher; in France they

had, moreover, the little octave flute in D (octave). A bass flute in

D had also been attempted (see fig. 5). When Ribock published his

_Bemerkungen uber die Flote_[37] the flute had already the five keys

here shown. [notes] This author states that the inventor of these new

keys is not known to him, but that either Kusder, a musical

instrument-maker in London, or Johann Georg Tromlitz of Leipzig was

the originator, since he has not been able to trace those keys on the

flutes of any other maker. Although Tromlitz does not claim for

himself the invention of the keys for F, G[sharp] and B[flat], he

states that "he had occupied himself for several years in applying

these keys so as not to augment the difficulty of playing, but on the

contrary to render the handling of them as easy as possible."[38] In

the later work published in 1800,[39] however, he seems to attribute

the invention of these keys to Richard Potter of London; he says that

he has never yet been fortunate enough to come across a good flute by

that maker--"the flute has certainly gained by the addition of the

keys for F, G[sharp] and B[flat], but this is not everything, for on

such a flute much must perforce be left unattempted.... Only a flute

with eight keys according to my invention is capable of everything."

It would seem, moreover, from circumstantial evidence stated clearly

and on good authority by Rockstro[40] that the keys for F, G[sharp]

and B[flat] must have been used first in England and made by Richard

Potter before 1774. The higher key of C adopted from 1786 by Tromlitz,

we believe to have been first recommended by Ribock (1782).[41]

Tromlitz in _Uber Floten_ describes at length what may be termed the

first systematic effort to overcome the difficulties created by the

combination of open holes and closed keys. He attempted to solve the

question by determining the positions of the holes according to the

exigencies of fingering instead of subordinating them to the more

arbitrary theories connected with the musical scale.

In 1785 Richard Potter improved Quantz's slide applied to the head

joint as well as to the register of the foot by a double system of

tubes forming double sliding air-tight joints. In the document[42]

describing this improvement Potter patented the idea of lining the

holes with silver tubes and of adapting metal conical valves to the

keys. Potter's patent conical valves were an adaptation of the

contrivance first invented by J.F. Boie or Boye of Gottingen,[43] who

used pewter for the plugs, and silver for lining the holes. The keys

mentioned in the patent were four--D[sharp], F, G[sharp], A[sharp].

The idea of extending the compass of the flute downwards was taken up

again about the same time by two players of the flute in London named

Tacet and Florio. They devised a new disposition of the keys C and C#,

and confided the execution of their invention to Potter. In Dr

Arnold's _New Instructions for the German Flute_ occurs a tablature,

the engraving of which goes back to the end of the 18th century, and

bears the following title, "A Complete Drawing and Concise Scale and

Description of Tacet and Florio's new invented German Flute, with all

the additional keys explained." It explains the use of six keys--C,

C#, D#, F, G#, A#--that are not always figured, because the employment

of so many keys was at once admitted. Tromlitz himself, who, however,

made flutes with nine keys--adding E[flat], another F, and C[natural],

declared that he was not in favour of so great a complication, and

that he preferred the flute with only two keys, D[sharp] and E[flat],

with a register foot joint and a cork nut-screw at the head joint.

This instrument met all requirements. He was always much opposed to

the use of the old keys for C[natural] and C[sharp], because they

altered the recognised quality of tone of the instrument. When

Tromlitz published his method, the family of flutes had become

modified. It comprehended only the typical flute in D, the flute

d'amour a minor third lower, a "third" flute a minor third higher,

and, finally, the little octave flute.

While Tromlitz was struggling in Germany with the idea of augmenting

the compass of the flute downwards by employing open keys for

C[natural] and C[sharp], an Italian, Giovanni Batista Orazi,[44]

increased the scale of the instrument downwards by the application of

five new keys, viz. B, B[flat], A, A[flat], and G. At the same time

that he produced this invention [45] he conceived the plugging of the

lateral holes by the valve keys then recently invented by Potter. But

it was hardly possible to obtain a perfect plugging of seven lateral

holes with the aid of as many keys, for the control of which there

were only the two little fingers, and therefore this invention of

Orazi proved a failure.

In 1808 the Rev. Frederick Nolan,[46] of Stratford, near London,

conceived an open key, the lever of which, terminating by a ring,

permitted the closing of a lateral hole at the same time the key was

being acted upon. The combination in this double action is the embryo

of the mechanism that a little later was to transform the system of

the flute. Two years later Macgregor,[47] a musical-instrument maker

in London, constructed a bass flute an octave lower than the ordinary

flute. The idea was not new, as is proved by the existence of the bass

flute mentioned above. The difference between the two instruments lies

in the mechanism of the keys. That employed by Macgregor consisted of

a double lever, a contrivance dating from before the middle of the

18th century, of which the application is seen in an oboe of large

dimensions preserved in the National Museum at Munich.[48]

In 1811 Johann Nepomuk Capeller invented the extra D[natural] hole and

key, which is still in constant use on every flute of modern

construction.[49]

About 1830 the celebrated French flautist Tulou added two more keys,

those of F[sharp] and C[sharp], and a key, called "de cadence," to

facilitate the accompanying shakes.

To increase the number of keys, to improve their system of plugging,

and to extend the [notes] scale of the instrument in the lower

region,--these had hitherto been the principal problems dealt with in

the improvement of the flute. No maker, no inventor to whose labours

we have called attention, had as yet devoted his attention to the

rational division of the column of air by means of the lateral holes.

In 1831 Theobald Boehm, a Bavarian, happening to be in London, was

struck with the power of tone the celebrated English performer Charles

Nicholson drew from his instrument. Boehm learned, and not without

astonishment, that his English colleague obtained this result by

giving the lateral holes a much greater diameter than was then usually

admitted. About the same time Boehm made the acquaintance of an

amateur player named Gordon, who had effected certain improvements; he

had bored the lateral hole for the lower E, and had covered it with a

key, while he had replaced the key for F with a ring. These

innovations set Boehm about attempting a complete reform of the

instrument.[50] He went resolutely to work, and during the year 1832

he produced the new flute which bears his name. This instrument is

distinguished by a new mechanism of keys, as well as by larger holes

disposed along the tube in geometrical progression.

Boehm's system had preserved the key of G[sharp] open; Coche,[51] a

professor in the Paris Conservatoire, assisted by Auguste Buffet the

younger, a musical-instrument maker in that city, modified Boehm's

flute by closing the G[sharp] with a key, wishing thus to render the

new fingering more conformable to the old. He thus added a key,

facilitating the shake upon C[sharp] with D[sharp], and brought about

some other changes in the instrument of less importance.

Boehm had not, however, altered the bore of the flute, which had been

conical from the end of the 17th century. In 1846, however, he made

further experiments, and the results obtained were put in practice by

the construction of a new instrument, of which the body was given a

cylindrical bore, while the diameter of the head was modified at the

embouchure, the head-joint becoming parabolic (see fig. 2). The

inventor thus obtained a remarkable equality in the tones of the lower

octave, a greater sonorousness, and a perfect accuracy of intonation,

by establishing the more exact proportions which a column of air of

cylindrical form permitted.

The priority of Boehm's invention was long contested, his detractors

maintaining that the honour of having reconstructed the flute was due

to Gordon. But an impartial investigation vindicates the claim of the

former to the invention of the large lateral holes.[52] His greatest

title to fame is the invention of the mechanism which allows the

production of the eleven chromatic semitones intermediate between the

fundamental note and its first harmonic by means of eleven holes so

disposed that in opening them successively they shorten the column of

air in exact proportional quantities.[53] Boehm (_Essays_, &c.)

published a diagram or scheme to be adopted in determining the

position of the note-holes of wind instruments for every given pitch.

This diagram gives the position of the intermediate holes which he had

been enabled to establish by a rule of proportion based on the law of

the lengths of strings.

The Boehm flute, notwithstanding the high degree of perfection it has

reached, has not secured unanimous favour; even now there are players

who prefer the ordinary flute. The change of fingering required for

some notes, the great delicacy and liability to derangement of the

mechanism, have something to do with this. In England especially, the

ordinary flute retains many partisans, thanks to the improvements

introduced by a clever player, Abel Siccama, in 1845 (Patent No.

10,553). He bored the lateral holes of E and A lower, and covered them

with open keys. He added some keys, and made a better disposition of

the other lateral holes, of which he increased the diameter, producing

thus a sonorousness almost equal to that of the Boehm flute, while yet

preserving the old fingering for the notes of the first two octaves.

But in spite of these improvements the old flute will not bear an

impartial comparison with that of Boehm.

A flute constructed on a radically new system by Signor Carlo Tommaso

Georgi and introduced in 1896 places the technique of the instrument

on an entirely new and simple basis. The principal features of this

flute consist in an embouchure placed at the upper extremity of the

tube instead of at the side, which allows the instrument to be held in

a perpendicular position; no tuning cork is required. There are eleven

holes mathematically placed in the tube which give the semitones of

the scale; there are no keys. The eleven holes are fingered by the

fingers and thumbs, the C[sharp] hole being closed by the side of the

left fore-finger. All the notes are obtained by means of simple

fingering as far as G[sharp] of the third octave, the remaining notes

of which are produced by cross-fingering. For the convenience of

players with short fingers keys can be added, and the head of the

Georgi flute can be used with any cylinder flute. The compass of the

Georgi flute [notes] is almost the same as that of the concert flute;

viz. If the lower C and C[sharp] are required, extra holes and keys

can be added. Everything that is possible on the Boehm flute is

possible on the Georgi and more, owing to the simplicity of the

fingering; each finger having but one duty to perform, all trills are

equally easy. The tone is the true flute tone, brilliant and

sympathetic.[54]

The old English _fipple flute_, or _flute a bec_, is described under

the headings RECORDER and FLAGEOLET. (V. M.; K. S.)

2. In architecture the name "flute" is given to the vertical channels

(segmental, semicircular or elliptical in horizontal section) employed

on the shafts of columns in the classic styles. The flutes are separated

one from the other by an "arris" in the Doric order and by a "fillet" in

the Ionic and Corinthian orders. The earliest fluted columns are those

in Egypt, at first with plain faces without any sinking, subsequently at

Karnac (1400 B.C.) with a segmental sinking equal in depth to about

one-seventh of the width of the flute. The columns flanking one of the

"beehive" tombs at Mycenae have segmental flutes and are the earliest

Greek examples. In two of the earliest Doric temples at Metapontum and

Syracuse (temple of Apollo) the flutes are also segmental, but in later

examples in order to emphasize the arris they were formed of three arcs

and are known as "false ellipses," and this applies to nearly all the

fluting in Greek examples whether belonging to the Doric, Ionic or

Corinthian orders. The number of flutes varies, there being 52 in the

archaic temple of Diana at Ephesus and from 30 to 52 flutes in the

Persian columns according to the diameter of the column. In the Greek

Doric column 20 is the usual number, but there are 16 only in the

temples of Sunium, Assos, Segesta and the temple of Apollo at Syracuse;

18 in one of the temples of Selinus and the temple of Diana at Syracuse,

and 24 in the temple of Neptune at Paestum. The depth of the flute also

varies; in the Propylaea at Athens the radius is equal to the width of

the flute and the flute is segmental. In the Parthenon the radius of the

central part of the flute is greater than the width, but the smaller

arcs on either side accentuate better the arris. A similar accentuation

is found in the Ionic and Corinthian orders, where the flutes are

separated by fillets, and their section is always elliptical in Greek

work, the depth of the flute, however, being always greater than in the

Doric order. Thus, in the temple of Ilissus and the Ionic column in the

cella of the temple at Bassae, the depth is about one-quarter of the

width, in the Propylaea at Priene it is about one-third, and in the

Erechtheum and other examples of the Greek Ionic order it is little more

than one-half. The width of the fillet also varies, being as a rule one

quarter of the width of the flute; and the same applies to the Greek

Corinthian order. In the Roman Doric, Ionic and Corinthian orders, the

flute is either segmental or semicircular, its depth being about one

third of the width in the Doric column, and in all Ionic, Corinthian and

Composite columns half the width of the flute. The fillet also is much

broader in Roman examples, being about one-third of the width of the

flute. In Roman columns sometimes the flutes of the lower part of the

shaft, about one-third of the height, are partly filled with a convex

moulding, "cabling" being the usual term applied to this treatment. The

French architects of the 16th and 17th centuries carried this decorative

feature much farther, and in the Tuileries and the Louvre carved a

series of leaves in the flutes. In a few Italian buildings, instead of

the fluting of the column being vertical, it twines round the column and

is known as spiral fluting; a fine example is found in the Bevilacqua

palace at Verona by San Michele. Fluting is sometimes introduced into

capitals, as in the tomb of Mylasa, and in friezes, as in the theatre at

Cnidos, the Incantada at Salonica, and a doorway at Patara. In one of

the museums at Rome is a fine sarcophagus, the sides of which are

sculptured with flutes in waved lines. The coronas of many of the Roman

temples were carved with flutes. In medieval buildings, fluting was

occasionally introduced in imitation of Roman work, as in the churches

of central Syria and of Autun and Langres in France, but in the south of

Italy and Sicily it would seem to have been brought in as a variety of

treatment, in the decoration of the shafts carrying the arches of

cloisters, as at Monreale in Sicily and in those of St John Lateran and

St Paul-outside-the-Walls at Rome. (R. P. S.)
