Chapter VII

HAYDN was the third great orchestral innovator in historic evolution, and from him date the beginnings of modern orchestration, just as Bach represents organ and Protestant Church music, Händel the oratorio, and Gluck the drama. Monteverde established the precedent of a nucleus of strings, Scarlatti adjusted their tonal balance, but Haydn readjusted the equilibrium of the suppletory segments of the orchestra as a concrete entity. His symphonies were the outcome of the earlier _concerto grosso_, and thus, having remained true to the traditions of his great predecessors, he became in turn the pioneer for Mozart and Beethoven. In his scoring, the wood-wind acquired freedom and individuality as solo instruments, and, together with the brass, were led also to sustain and knit together the harmonic progressions, rather than merely to support the resonance of the strings. He emphasized the consistent use of wind instruments in pairs. Again, by exploring further their caloric capabilities, he discovered effective means for descriptive music, and his oratorios bear the seed of programmatic writing.

MOZART explored the resources of the orchestra as opened up by Gluck and Haydn. He combined and interchanged polyphonic and monophonic style of writing to a most felicitous degree. He wrote for the strings in such a manner as to insure absolute independence and stability. The wood-wind gained in freedom of solo expression, and acquired that individuality of treatment which was its own by right. Especially the clarinet owes its absorption into the orchestra to Mozart, and from him dates the genuine origin of varied and contrasted tone-coloring.

The universal genius of BEETHOVEN, prompted by the depth of his nature and the nobility of his purpose, led him to combine the legacy of his predecessors with a more sensitive regard for inner details, thematic unity, emotional expression, and greater freedom and subordination of form, leading to expansion and programmatic music. Greatest of classic orchestral masters, he brought the symphonic orchestra to its highest development, discovered the utmost capabilities of each and every instrument, increased the efficiency of both strings and wood-wind, and incidentally discerned the genuine worth of the violoncellos, bassoons, and kettle-drums. The functions of the horns likewise acquired wider significance, and the trombones were reserved for the portrayal of noble dignity and ornamentation.
