Thus we come to the period of Bach and Händel, both of whom began to write shortly after 1700. In the working out of their respective talents, both these composers show their well-schooled musicianship, according to all the learning of the contrapuntal schools--but with very important differences. Händel had all his life a predilection for diatonic tonality, and it is very rarely indeed that he deals with the chromatic at all, and never with the enharmonic. All the music in which he best expressed himself was written for voices, and as a master of vocal effect he still holds a distinguished position, particularly in the creation of compositions in which a large number of voices can be effectively massed. He also had a distinct flavor of the folk-song in many of his melodies, and in some instances the folk-song is the entire work. Such, for instance, is the case in "See, the Conquering Hero Comes," in "Joshua," and in several of the short instrumental movements in "Joshua," "Solomon," and his other oratorios.
Bach, on the other hand, was of a much more intensely organized musical temperament. His genius was of the greatest possible character. As a virtuoso he not only played upon the organ, the clavecin, and the violin better than most of his contemporaries, and upon the organ probably better than any; he also created works in these three departments which held the attention of his own time to an astonishing degree, considering the meager means of communication among men, works which still remain, in our time, the indispensable corner-stones of the literature of these three instruments. The violinist gets a large part of his mastery through the sonatas of Bach for violin solo, the organist learns his art from Bach, and the pianist finds "The Well-tempered Clavier," and many other works of Bach written for the clavecin of indispensable importance for the development of intelligent playing.
The peculiar importance of Bach to modern music lies in the delicacy of his sense upon the harmonic side and upon his intuition of the emotional value of musical combinations. In the form of his work he always more or less resembled his predecessors, the fugue underlying, probably, something more than half of all the music he wrote. But he also showed a strong tendency to impart to his work the vivacity of the folk-song and the expressive melodic quality which he had already found in the violin. Owing to his intensely sensitive harmonic perceptions, he was never able to confine himself for long to the more obvious chords of the key. The diatonic chords and combinations in which Händel found an ever complete satisfaction are not sufficient for Bach, and we find continually new chords, evasive cadences, and a flowing continuity of thought belonging to the master mind.
