The revival of Greek learning led also to an attempt to resuscitate the dead Greek drama, or rather to reconstruct the Italian play on its lines. The fact that the Greeks had chanted rather than declaimed their dramatic texts suggested to the little band of Italian enthusiasts led by Galilei, Peri, and Caccini, an attempt to reproduce this musical delivery. Their efforts resulted in the invention of dramatic recitative and the birth of opera. With the advent of this form of vocal art the supremacy of church polyphony was overthrown. It did not cease to exist, but it lost its dominion over the musical world, and it almost stopped developing. To this day the works of Palestrina composed in the second half of the sixteenth century remain the model and the despair of church composers. Handel and Bach, introducing more modern harmonies and employing the resources of the orchestra, which Palestrina and his predecessors never used, carried vocal polyphony a little further, but their advance was external rather than fundamental.
It was at this stage of musical progress that the orchestra made its appearance,—a feeble, tottering, purposeless instrumental infant. Collections of instruments had of course existed. Millionaires of the Middle Ages drowned the inanities of their dinner conversation with banquet music, just as the moderns do. But their assemblies of instruments were merely fortuitous. Any instruments which chanced to be in the house, and for which there were players, were utilized. There was no music specially written for these orchestras. We may suppose that they played the popular tunes of the day. When the opera came into existence, some sort of orchestra had to be extemporized. Here again in the beginning any instruments easily accessible seem to have been taken up. It was not till Claudio Monteverde began his experiments in instrumental combinations in his operas in the early part of the seventeenth century that anything like method in instrumentation was discernible.
Monteverde began the exploration of the resources of each instrument in characteristic expression. He endeavored to measure the powers of the viol, the trumpet, the organ, and certain combinations of instruments as illustrators of dramatic action. He invented some of the now familiar tricks of orchestration, such as the tremolo and the pizzicato. Furthermore he created an instrumental figure to imitate the galloping of horses and another to depict the struggle of a combat, and thus was really the artistic progenitor of Richard Strauss, with his battle dins and his pirouetting maids. Succeeding composers were not slow to follow the suggestions offered by the work of Monteverde. The opera became a field for instrumental experiment, and the orchestra, as employed by the operatic composers, was continually in advance of the symphonic orchestra in the variety and extent of its combinations and in the utilization of the special powers of each individual instrument. This continued to be the case up to the time of Liszt, Berlioz, and Wagner, when the technics of conventional orchestration were so thoroughly established that the demands of the new romantic school of composers affected the orchestra simultaneously in opera and symphonic composition.
That the operatic orchestra should have taken the lead was perfectly natural. When vocal polyphony was deposed from its supremacy, instrumental music was in its infancy. Only the organ had achieved anything approaching independence, and that was because all the leading composers had been writing for the church and knew the church instrument. For practice at home they used the clavichord, one of the forerunners of the piano, and they began presently to compose special music for it, but in the style of their organ music. Gradually they fell into the way of writing for small groups of instruments, and after a time the orchestra found its way from the opera house to the church, and the orchestrally accompanied mass came into existence. But meanwhile the composers who wrote for the clavier, with the aid of those who wrote for the solo violin, were fashioning a form, and after a time the sonata began to assume a definite shape. Now it was borne in upon composers that their auditors would not arrive at the opera in time to hear the overture, for operatic publics were much the same then as they are now; and the poor composers had recourse to writing their overtures so that they could be played independently and having them performed at concerts. As these overtures were written in a form founded upon the principles of the sonata form, nothing was more natural than that gradually composers should be led to the composition of complete sonatas for orchestra, and a sonata for orchestra is a symphony.
In the middle of the eighteenth century, then, after Sebastian Bach had carried the piano solo through the splendors of his "Well Tempered Clavichord," and the piano sonata had attained something like defined shape, we see Stammitz, Gossec, and, at length, Haydn producing thin, tentative weakly orchestrated sonatas for orchestra, and the real development of independent orchestral composition began. This was nearly a century and a half after the birth of the orchestra as an adjunct to the opera, and the same length of time after the beginning of independent composition for the clavichord. In other words, although the modern art of music may fairly be said to have begun at least as early as the beginning of the twelfth century, when the fundamental principles of counterpoint were enunciated by the French masters, the most splendid and powerful of all musical instruments, the orchestra, is to-day in its infancy. For if the masters of vocal polyphony took some twelve centuries to elaborate their science, it is fair to presume that, even though the general laws of music are now firmly established, the technics of the orchestra and of orchestral composition, which are a little over a hundred years old, are yet by no means fully understood.
The method of composition employed by the early masters of orchestral music was elaborate, yet not recondite. It was a system of architecture in tones, and its achievements were distinctly satisfying to the æsthetic discernment and to the appetite of the human mind for a logical arrangement of ideas. Four parts or movements were allotted to a symphonic work. Contrast of time, rhythm, key, and harmonic color was sought. Each movement differed from that next to it. Variety in unity was the ultimate object. But each movement had to have a well-defined shape within itself. Two melodic ideas, complementary to each other in key, rhythmic nature, and sentiment, were invented. They were held up for the inspection of the hearer at the beginning of the movement Then the composer embarked upon what was called the "working out." He took the essential features of his two melodies and juggled them through the tricks of musical metamorphosis. He dressed them in new harmonies; he made them writhe in the embraces of counterpoint; he expanded them into new melodies; he sang them with the different voices of the instrumental body. In the end he repeated them in their original shape, and brought his movement to a close. The entire purpose was the treatment of themes. The only aim was to make symmetrical, intelligible, interesting music.
In evolving this form the composers fell, as I have said, into a conventional use of their orchestra. They had three choirs, one of wooden wind instruments, one of brass, and one of strings played with bows. They allotted fixed functions to each choir and to the members of each, and there they stopped. Occasionally a hint from the operatic treatment of the instruments enlightened them and they made a slight advance, but nevertheless, when Beethoven came to write his symphonies, in which he attempted to make orchestral music attain something more than mere musical beauty, he found himself hampered by the conventionalities of symphonic orchestration, as well as by those of the symphonic form. It was the limitation of the form, indeed, which restrained the instrumentation. The form itself had first reached definiteness with Haydn, who died when Beethoven was thirty-nine. Only in his later years did Haydn learn the use of clarinets, the most important members of the wood wind choir.
Beethoven, striving to make the symphony a vehicle for emotional expression, was compelled to busy himself with changes in the form, and he gave no special study to instrumental effects. He used such new ones as readily suggested themselves to him, but they were nothing more than elaborations of the old conventions. However, the seed sown by Beethoven speedily bloomed in the growth of the new romantic school. The principal tenet of this school was that music must express emotions, and that the form must develop entirely from the emotional purpose and plan of the work. Two distinguished explorers of this new style devoted their highest efforts to the production of orchestral composition.
Liszt endeavored to tell stories in music by erasing the dividing line between movements and writing his work all in one piece. He retained the two contrasting themes of the old symphonists, but he asked his hearers to affix a meaning to each of them. Then he proceeded to handle them in much the same way as the symphonists did, working them out, and varying them with much skill, though always with a view to suggesting the development of the incidents of his story. To such a purpose the resources of orchestral color lent mighty aid, and Liszt was not slow to perceive this. He began to draw away from the conventions of the symphonists, and to seek for new and striking instrumental combinations. Nevertheless in his compositions for orchestra Liszt was the debtor of two men much more remarkable than himself, namely, Wagner and Berlioz. From the former he got the idea of the use of themes with definite meanings attached to them. From the latter he obtained the suggestion of the employment of the orchestra to tell stories and much information as to its technics. Berlioz, however, continued the use of separate movements, and his attempts to use definitely representative themes were few and uncertain. He preceded Wagner, nevertheless, in the revelation of the resources of the orchestra, and he antedated Liszt in the use of the orchestra for romantic composition.
Later imitators of Berlioz and Liszt failed to perceive anything except the vast color schemes of their orchestration. Borrowing a few of the conventional figures of the older writers, such as Haydn's sea waves and Beethoven's thunder-storms, they asked us to see things through a kaleidoscope of instrumental color. They forgot that we could not understand them when they made no logical appeal to our intelligence.
