Bach and Handel.—We now come to the period of Bach and Handel, each distinct in methods, the latter the more immediately influential in the development of the orchestra, the former’s principles of writing in the polyphonic style not being taken up until after years by Wagner and more recently by the extreme modern composers with their free polyphony. In a Bach score each instrument had an independent part to sing, and was treated from a musical standpoint, whereas the tendency of other composers was to seek figures and passages which should be characteristic of the instrument, the standpoint of effect. This particularly applies to the wind instruments. Handel’s idea seemed to be the building up of great mass effects, his style partook of the harmonic rather than the polyphonic. He used all the important instruments found in the modern orchestra except the clarinet, although the proportion of the wind instruments to the strings is greater, due to the relatively inferior power of these instruments in Handel’s time.

Haydn and Mozart.—From Handel we pass to the first of his three great successors, Haydn, who has been called the “father of the symphony,” who determined, in fact, the course of orchestral development. And we should not overlook the fact before-mentioned, namely, that the professional violinists, most of whom were also directors of orchestras in the pay of great princes, were testing the capacities and resources of the instruments used. In the period which Haydn represents, the proportions of the instruments in the orchestra were definitely fixed and the size of the string band became relatively greater, the ’cello coming in to greater prominence in its use as a melody instrument. Haydn’s last symphony, written in 1795, calls for two flutes, two oboes, two clarinets, two bassoons, two kettle drums, and the usual string band. This was the combination which Haydn selected as the most useful and effective, as the result of his experience as a conductor for many years. It was to Mozart that the introduction of the clarinet into the orchestra is due, for Haydn did not employ this instrument in his earlier works. The clarinet began to take an effective form about the end of the 17th century, yet it was not until the 19th century that it received the improvements that now make it one of the most useful instruments in the orchestra, with a wonderfully facile technic and correct intonation. The greatest of these changes was the application, to the clarinet, of the system of keys and fingering invented by Theobald Boehm (1794-1881) for the flute. In addition to showing the value of the clarinet as an instrument, Mozart pointed the way to some uses of the trombone. His E-flat Symphony is scored for one flute, two clarinets, two bassoons, two horns, two trumpets, tympani and strings; in the score of the “Jupiter” symphony, the clarinet does not appear.

Beethoven established the orchestra as “the composer’s instrument.” He added but little to the instruments used but he took the resources established by his predecessors and demonstrated what could be done with them. Every group of instruments was used with more detail and to produce characteristic effects both separately and in combination. In his first and second symphonies he uses the same orchestra: two flutes, two oboes, two clarinets, two bassoons, two horns, two trumpets, tympani and strings; in the “Eroica,” a third horn part is added; the fourth has the same orchestra as the first two, except that one flute is dropped; the fifth calls for piccolo, two flutes, two oboes, two clarinets, two bassoons, contra-bassoon, two horns, two trumpets, three trombones, tympani and strings; in the sixth he uses the same orchestra as in the fifth, except that he drops the contra-bassoon and one trombone; in the seventh and eighth the orchestra is the same as in his first and second symphonies. In the ninth (Choral Symphony) he calls for a larger orchestra: piccolo, two flutes, two oboes, two clarinets, two bassoons, contra-bassoon, four horns, two trumpets, three trombones, tympani, triangle, cymbals, bass drum and strings. It will be noted that Beethoven does not use the harp. It was not until 1820, seven years before Beethoven’s death, that Erard invented the double-action harp, an effective and a playable instrument.

Berlioz, Wagner and Richard Strauss.—The composer who first made an exhaustive study of orchestral instruments, their distinctive qualities, separately and in combinations, was Berlioz, who gave to the world his knowledge in his “Treatise on Instrumentation,” published in 1844. Berlioz gave to every one of his works a more or less distinctive quality by varying the composition of his orchestra instead of using the conventional combinations. He made frequent use of the harp, bass clarinet, English horn, bass tuba, besides other less frequently used instruments. He very much enlarged the scope of orchestral music by the new effects he devised. Richard Wagner, in his great music dramas, makes use of many new means of dramatic musical effects, introducing new instruments, enlarging the various families, dividing the strings into eight parts, increasing the number of brass instruments, giving to his scores a richness of power and a sonorous quality unknown before his time. Richard Strauss is, today, the greatest master of the technic of orchestral writing. His tone-poems make greater demands on the resources of the instruments and contain effects beyond those of Wagner.

Hector Berlioz.

Hector Berlioz (1803-1869) was the son of a French physician, who designed him for his own profession. But the lad’s bent for music was so strong that when sent to Paris to prepare for a medical degree, he spent most of his time in going to the opera and in studying the scores of the masters. Much against the will of his parents, he determined to give up medicine and entered the Conservatoire. His early musical training had been far from thorough and his career was at first not successful. This added to his father’s displeasure, and he finally withdrew all support from his son, who, rather than abandon his art, struggled with the most crushing poverty until a violent illness brought on by privation reconciled his parents to his choice of a profession. After several unsuccessful attempts, he gained the great Roman Prize, which entitled him to a period of study in Italy and Germany at the cost of the State, but throughout his life he battled at home with adverse and discouraging conditions, artistic and domestic. Until after his death his works never received the recognition gladly paid them in foreign countries, where he made frequent tours for the purpose of producing them. His demand for exceptional means of performance, based upon their large scope and previously unheard-of effects, was ridiculed in France, where they were also considered dissonant and bombastic; he encountered jealousy and intrigue at every turn and bore them, too, in no patient spirit.

His Important Works.—As a winner of the Roman Prize, however, he had a claim on the State. Thus his great “Te Deum,” written for three choruses, soli, and orchestra, was one of several commissions from the Government and was composed for the opening of the Exposition of 1855. Another similar colossal work is his “Requiem,” with its four small orchestras of brass stationed at the corners of the principal orchestra. These cross and re-cross with thrilling effect, simulating the blowing of the last trump. His most popular and widely-known work, “The Damnation of Faust,” a dramatic cantata now frequently heard in this country and in Europe, failed to awaken the slightest interest at its first performance in 1846 and involved the composer heavily in debt. His enthusiasm for Shakespeare led to the composition of what some consider his most important work, “Romeo and Juliet,” a symphony for orchestra, solo voices and chorus. Berlioz’ genius was essentially instrumental and symphonic in character; hence, though he composed a number of operas, none was successful. Indeed, the failure of “Les Troyens” (The Trojans), the subject of which was taken from the “Æneid” and which he intended to be his masterpiece, was his death-blow.

His Genius as an Orchestral Composer.—Berlioz was the founder of the modern school of orchestration, as well as the pioneer in the art of expressing a definite program in terms of absolute music. Like his great contemporary, Wagner, he was no executant; he played but little and, curiously enough, only such insignificant instruments as the flute, flageolet, and guitar. The orchestra was his instrument and no one has ever had a more unerring instinct for its capabilities either as a whole or in its component parts. In the origination of weird, unearthly effects he had been anticipated by Weber, whom he greatly admired; but he went beyond him in devising bold and daring combinations, which he justified by the end in view, though it cannot be said that a refined taste always finds this end in itself justifiable. For example, in the last movement of his “Fantastic Symphony,” he pictures an execution by the guillotine. A company of witches and demons dance around the headless body and perform a burlesque requiem—the whole supposed to be a nightmare suffered by an artist under the influence of opium. Color rather than outline, thrilling and novel effects of sonority, rhythmical variety and animation, intensity of expression and dramatic climax are the principal characteristics of Berlioz’ music. Yet delicacy and charm are by no means lacking in his works. Irregular in proportion and unequal in inspiration as they frequently are, they undoubtedly entitle him to the distinction of being the greatest composer that France has yet produced.

The Music of the Orchestra includes Symphonies, Overtures, Symphonic Poems, Tone-Poems and Suites and the Concerto for a solo instrument with orchestral support. The symphony is an elaborated sonata, and the first movement is usually constructed on the principles recognized under the term Sonata-form; the same principles are used in the Overture, which consists of but a single movement. Liszt, in his efforts in the program music style, devised the Symphonic Poem, which aims to present a series of emotional pictures in the Symphonic style, but with the various movements continuous. He advocated deriving all themes from a common source, transforming them rhythmically as needed to work out his conception. His successors in this style of music still use the thematic methods devised by the writers in the true symphonic style, but are free in their methods of construction and elaboration.
