The first serious attention bestowed upon the mechanism of instruments and the selection of those whose qualities should justify permanent retention occurred during the sixteenth century, and, as we have seen, the causes that led up to this were extraneous. In glancing over the names and descriptions of the many varieties of instruments already in existence before this development began, the mind becomes easily confused. Many species of stringed instruments such as lutes, viols, clavichords, harpsichords, not to mention brass instruments, the schalmei, cromornes, abounded on every hand; but the deeper the student of instrumental evolution delves into comparative research, the more he finds authorities at variance. However, the lineage of the three great representatives of stringed instruments as are in use to-day—instruments played with a bow, the harp, the pianoforte, may fairly be traced simultaneously.

I.

Prehistoric origin of stringed instruments, in spite of extant relics, is a matter of conjecture. History, on the other hand, suggests various sources in various ages. Of greatest recorded antiquity are the Egyptian lute and harp, which were struck with a plectrum or plucked by the fingers. These migrated through Arabia into Spain, thence to Southern Italy, and became diffused over all Europe. The Greek lyra or kithara, having originally but four strings, was also played with a plectrum, and became the heirloom of the Romans. But to discover the origin of instruments played with a bow is a more difficult matter. A number of theories are plausible. Like all other instruments they were probably invented simultaneously by many isolated barbaric races. The bow and arrow were undoubtedly suggestive, and it is to be presumed that primitive types of the lyre family whose strings were originally plucked, were fitted to uncouth sounding-boards and played upon with a bow. The Hindoos possessed such instruments, and it is possible that their admission into Europe was concurrent with that of the lute and harp. In defence of this supposition, one might point to the dance of the women attending the Jongleurs. Now the dance is no uncertain revealer of racial characteristics. But not only the dance itself, but also certain features of the accompaniment, as well as the types of instruments peculiar to the Jongleurs bear the impress of Orientalism. As far as is known, neither the Greeks nor the Romans possessed instruments played with a bow.

From the Middle Ages on, the study of instrumental evolution is, of course, based upon authentic history. The most direct line of descent for bowed-instruments is probably from either the Celtic crwth or the Oriental rebab to the vielle or viola of the Middle Ages (Spanish vihuela, Latin fidula), of which the last representative was the gamba; and the viola da gamba was the predecessor of the violoncello. The early viols were of manifold types, there being, for instance, as many as seven viole da braccia and six viole da gambe. The violin owes its existence to a gradual metamorphosic development of the early tenor viola, during the latter part of the fifteenth and early sixteenth centuries. Skill in the manufacture of these instruments was of an advanced order in the Netherlands prior to the advent of the great Italian violin makers, whose efforts were eventually crowned by the immutable sovereignty of the Cremonese creations at the commencement of the eighteenth century. The introduction of the contrabasso was likewise of slow growth. For as late as the seventeenth and eighteenth centuries there still existed bass instruments of the lute family, such as the double-necked theorbo and the largest bass lute, the chitarrone, which were struck with a plectrum. But growing appreciation for the wonderful possibilities concealed in the infant violin proper, of technique, tone, color, delicacy, and variety of shading, reacted upon the secondary bowed-instruments, and they in turn were rapidly perfected. Hence, by a judicious selection of the superior and a suppression of the inferior types of viols were the violas and violoncellos evolved; and the theorbo and chitarrone were permanently supplanted by the double-bass, constructed on the same general principles as the violin.

Although the ideal balance of tone and expressive powers as embodied in the modern string orchestra justifies the perspicuity of this selective process in every way, it would seem to be a matter for regret that a certain species of viols, the viola d'amore, should have become practically obsolete. Its seven strings were supplemented by seven concealed under strings, designed to vibrate sympathetically. One might say that this principle has been incorporated in the modern grand pianoforte by means of the "una corda" pedal. But since Meyerbeer resuscitated the viola d'amore in "Les Huguenots" in 1836, the only living composer who has assigned to it a conspicuous rÔle is, to the present writer's knowledge, Mr. C.M. Loeffler in his symphonic poem "La Mort de Tintagiles," after Maeterlinck, indeed the original score contained parts for two solo viole d'amore though one part has since been rewritten for a violin.

II.

The evolution of the harp is obvious, whereas that of the pianoforte is more complex. The prototype of the modern pianoforte in its embryonic state traces its ancestry to all the various types of stringed instruments taken collectively. Specifically, the primitive acoustic monochord of Pythagoras might be looked upon as a plausible starting point. Add to this a keyboard and its attendant devices as applied to church organs in the earlier centuries of the Christian era, and the prototype is complete. Be that as it may, there was developed during the fourteenth and fifteenth centuries a family of widely known instruments embodying advanced qualities of mechanism, styled "Hackbrett," synonym for cembalo, tympanon, although it is best known as the dulcimer. According to Dr. Riemann, it originated apparently in Germany, since for a time it was called in Italy by the name of Salterio tedesco. The instrument consisted of a flat trapezium-shaped sounding-board on which steel strings were set, and was played upon by two hammers held one in each hand of the performer. In improved form, it is still extant in the hands of the gypsies. But already at the beginning of the sixteenth century was the clavichord established as its successor. The clavichord, according to Hipkins, was derived from the polychord with four strings, which in turn was developed from the monochord "to facilitate the melodic division of the Gregorian tones." Directly appeared still another instrument styled clavicembalo or harpsichord, of which the psaltery, a triangular harp, was undoubtedly the ancestor. The spinet and virginal differed from the harpsichord only as to shape; and in England, virginal was the general term for spinet and harpsichord. The cardinal point of dissimilarity between the mechanical construction of the clavichord and the harpsichord was that the strings of the former were caused to sound by means of metal tangents, which struck against the strings and then pressed them up, whereas the strings of the latter were plucked by hard quills set in wooden jacks. But of far greater importance was the difference of tone-quality. The tone of the clavichord was delicate, subdued,—incapable of energetic utterance, but so expressive that it was a favorite with great musicians; that of the harpsichord was crisp, short, uniform. A radical readjustment of mechanism was found necessary in order to combine in one instrument euphony and variation of dynamic force. Therefore in the beginning of the eighteenth century hammer-action was invented, and the pianoforte, derived from the dulcimer, came into existence. Despite this fact, both the clavichord and the harpsichord continued to hold their own beyond the boundaries of that century. And so we see that the perfected modern pianoforte, being but the outcome of a variety of instruments already in existence three hundred years ago, was unable to supersede them until the nineteenth century.

Turning our attention again to instruments belonging to the orchestra proper, we find an inexhaustible subject in the evolution of the two other great families, the wood and the brass. Most of the above-advanced hypotheses in respect to origin and migration of strings are equally pertinent to the wind. But the inference that the genesis of these latter instruments antedates that of the lyre and lute is surely justified in that conch shells and the horns of animals must have offered the most natural means for producing artificial musical tones. Again, the construction of stringed instruments suggests a more advanced stage of intellectuality. Finally, there have been preserved to us from antiquity a far more numerous and varied array of comparatively natural instruments such as the Egyptian mem and sebi,—respectively vertical and horizontal flutes, of which the former was more common and still exists in the guise of the modern Arab flute. One of the most simple species of horn was the "Schofar" or ram's-horn, used in the temple worship of the Hebrews. The Assyrians as well as the Egyptians possessed trumpets, probably of brass. The war trumpets of the Romans were of bronze. The deep-toned trumpet or tuba was straight; the high-toned lituus was bent; and the buccina, large trumpet or trombone, was curved.

III.

The principle of both single and double reeds was understood by the Greeks. As a result of the researches of Professor A.A. Howard, an accurate description of their representative instruments, the auloi, Latin tibiae, is to be found in "Harvard Studies in Classical Philology," Vol. 4. His article presents strong arguments in favor of the belief that instrumental polyphony was actually practised by the Greeks. Performers upon the auloi played almost invariably upon two pipes at once. The instruments were supplied with finger-holes, were capable of producing both the diatonic and chromatic scales, and may be divided into three classes corresponding, in a general way, to the three types of wood-winds as are in use to-day. All of them had a tube of cylindrical bore, but most of them were supplied with a double mouthpiece like the modern oboe, so that these species of the auloi can be regarded as the prototype of the preferred double-reeds that prevailed during the Middle Ages when they went under the name of schalmei. This nomenclature is confusing; in explanation it should be said that not until after the original schalmei had developed into the pommer, thence to the oboe, was the single-reeded predecessor of the clarinet known by this name. Colloquialism refers to the schalmei in its later application.

Another double-reed that came into temporary existence during the Middle Ages was the variety of cromornes. They differed from the schalmei principally as to form—Krummhorn.

The successors of the original schalmei are described in detail by Praetorius, who wrote in the first decade of the seventeenth century. Of the six varieties of pommer mentioned by him, the treble pommer became transformed into the hautbois (high wood); the alto pommer into the cor Anglais (cor anglÉ, bent horn),—known during the seventeenth and eighteenth centuries as the oboe da caccia; and out of the bass pommer, likewise styled bombarde, emanated the fagotto (bundle of fagots). As a commentary to the above enumeration one should take note of a quite remarkable tendency which was, indeed, already in vogue during the Hellenic age. Namely, that from each parent instrument whether string, wood, or brass, there germinated a complete family representing the four ranges of the human voice. And again from these the process of tribal expansion was carried yet further. Moreover it must be remembered that before the Middle Ages, the art of combining human voices in polyphony was but in a nascent state, and probably existed in classic Greece not at all. Therefore families of instrumental species cannot have been constructed for the purpose of obtaining homogeneous harmonic effects. An extensive range of con-natural tone-color was then the objective. It will be found that this tendency was uniform throughout the history of instrumental evolution. Of course when we reach the sixteenth century, we find that the advantage of distributing the components of harmony among the members of assimilated instruments began to be appreciated. It is possibly due to this natural evolution that innovators in orchestration at first accustomed themselves to the use of pure tone-color rather than of mixed tints. Thus in the sixteenth century, the flÛte À bec, predecessor of the modern flute, was employed in groups of four. Praetorius makes mention of no less than eight different kinds as prevalent in his day. Our chief representative of the single reed, the clarinet, which was not invented until the end of the seventeenth century, owes its origin to a primitive form of instrument with clarinet mouthpiece:—the mediÆval chalemiax or chalumeau, whence the phonetic rendition, schalmei. The now obsolete basset-horn belongs properly to this genealogy. It was frequently used during the time of its development by the composers of the latter eighteenth and early nineteenth centuries. From it were devolved the short-lived alto and tenor clarinets, and the better qualities of all three are now embodied in the subsequently perfected bass-clarinet. Mention is also due to the saxophone, invented by Sax in 1840. It should be classed under the heading of wood instruments rather than of brass, since its tone-quality partakes somewhat of the nature of the clarinet. It has a single-reed mouthpiece, and the fingering is akin to that of the clarinet; but the over-blowing produces the octave as in the flute and oboe, whereas in the clarinet the twelfth is produced. Sax made seven different sized saxophones, of which four are commonly in use, and that particularly in French and American military bands.

IV.

The history of brass instruments is extensive; at the same time their development is easy to trace. But it must be remembered that only those instruments possess pedigree from which upper harmonics are produced, i.e. those constructed with long tube and narrow bore. Even this statement must be qualified in that the French horn is of modern extraction. Only trumpets and trombones, therefore, are directly descended from the early Roman instruments with cup-shaped mouthpieces, such as the lituus and buccina. And in the Middle Ages there existed side by side two such families,—the Zinken, and the trombe and tromboni. The Zink or cornetto had a wooden tube pierced by sounding holes, and was constructed in different sizes. The larger species was, at the close of the sixteenth century, transformed into the Serpent, which had a bell of brass. This instrument is still in use in some Italian military bands. The Zinken were extant in the hands of the "town musicians" even into the eighteenth century. Akin to them are the simple Alpine Horn and the Lur of Norway.

In the Middle Ages the trumpet was generally made of brass, and the tube was at first unbent. The principle of sliding tubes for the purpose of procuring additional tones to the natural ones of an instrument was of ancient origin. It was applied to trumpets as well as to trombones, a practice still in force in England. The obvious advantage of this device was that a complete chromatic scale could be obtained, impossible for all other brass instruments at a time when crooks and valves were unknown. The earlier name for the trombone, i.e. bass trumpet, was sackbut, but the original appellation, buccina, has been perpetuated in the German Bosaun, now Posaune.

In the sixteenth century, the tromba, synonym for clarino, trummet, together with the three genres of trombones as used by the subsequent great classicists, was already perfected as a sliding-tube instrument. Or one might include both instruments under one heading by speaking of the tromba as a treble trombone. However, in order to obtain more efficient high brass instruments, constant experiments were made. The earlier improvements had obviated the clumsy length of brass instruments by bending and rebending their tubes. Then followed the application to the brass of the finger-hole system of the wooden Zinken. Finally, in the eighteenth century, the introduction of removable crooks improved the trombe as far as quality of tone is concerned. But the highest point of evolution was arrived at early in the nineteenth century, when the perfection of the chromatic valve principle revolutionized not only the mechanism but also the manner of writing for trumpets as well as for horns and bugles.

As has been intimated above, the history of the French horn is short. There is but a slight analogy between it and the cor de chasse of the Middle Ages, an instrument that possessed but few tones. The genuine French horn made its appearance in the first half of the seventeenth century, and the stages of its development may be regarded as centennial. In the eighteenth century was added the crook principle, in the nineteenth, the valve system. These improvements were attendant upon those made upon trumpets. Like the trumpet, the "natural" horn was conducive to purity of tone, the chromatic horn to greater practicability without material loss of purity.

The family of bugles belong more properly to the subject of military bands, but a word is due to their evolution on account of the orchestral importance of one of their members—the bass tuba. The bugle-horn, also known as the sax-horn, is constructed on acoustic principles diametrically opposed to those of the trombe family in that the bore is wider and the tube shorter, whereby the principle of obtaining harmonics is reversed.

The date of Beethoven's birth signalized the first application of key mechanism to wood instruments. Simultaneously, experiments were made upon the now obsolete brass Zinken. The new instrument was called bugle À clefs, and was the forerunner of a group of different sized opheicleides, of which the lowest supplanted the sixteenth century Serpent. Subsequently the opheicleide itself was superseded by the bass tuba, a more noble instrument of the same general family.

V.

The evolution of instruments of percussion requires but brief mention. Sound-producing apparatus devoid of definite pitch belongs to the initial attempts of primitive men to assist vocal expression of emotional feeling, to accompany religious orgies, or to encourage their warriors on the march. The modern orchestra includes the best of these primitive species, transformed into perfected types of genuine artistic value, and has also drawn into requisition various instruments originating in countries that are far apart. Most commonly used are the bass-drum, the cymbals, and the triangle. The family of drums further includes the long side-drum and the small military drum. With the cymbals and triangle belong the tam-tam or Chinese gong, the Oriental and Spanish tambourine, the Spanish and Neapolitan castanets, and the Turkish crescent or bell-rattle. The use of all such instruments is, of course, the exception rather than the rule. Their mission is primarily to suggest "local" coloring or to emphasize rhythm for dancing.

Instruments of percussion possessing definite and variable pitch are represented primarily by the kettle-drums, which are constant and indispensable members of the orchestra. The early Hackbrett or dulcimer might also be classed under this heading, which further includes the various sets of bells, such as the carillon or Glockenspiel of Chinese origin, together with the Stahlspiel or Lyra, and the Xylophone.

This sketch demonstrates the fact that the early evolution of instruments went hand in hand with that of music in general and is subject to identical hypotheses. With the dawn of secular music, the development of instrumental construction and mechanism is focused upon the sixteenth century, with emphasis upon the anterior practice of employing complete homogeneous groups.

In order to cover the entire ground, this survey of the development of musical instruments has necessarily transgressed the bounds of the sixteenth century perspective. And since we are about to recontinue a critical review of the orchestra as inherited by Monteverde, it will be well to remember that in his day the only orchestral instruments in the modern sense of the word were violins and viols, harps, flutes, pommers, cornetti, trumpets, trombones. In combination with these, lutes, guitars, organs, the clavichord and the harpsichord were still employed.
