Zachau was a broad-minded man and moreover a good musician, whose greatness was only appreciated many years after his death.[8] His influence on Handel was splendid. Handel himself did not conceal it.[9] This influence affected the pupil in two ways: by his method of teaching, and by his artistic personality. "The man was very well up in his art," says Mattheson,[10] "and is possessed of as much talent as beneficence." * * * * * Handel's devotion to Zachau was so great that he seemed never able to show him sufficient affection and kindness. The master's first efforts were devoted to giving the pupil a strong foundation in harmony. Then he turned his thoughts towards the inventive side of the art; he showed him how to give his musical ideas the most perfect form, and he refined his taste. He possessed a remarkable library of Italian and German music, and he explained to Handel the various methods of writing and composing adopted by different nationalities, whilst pointing out the good qualities and the faults of each composer; and in order that his education might be at the same time theoretical and practical, he frequently gave him exercises to work in such and such a style. * * * * * This education with a true European catholicity was not confined to one particular musical style, but spread itself out over all schools, and caused him to assimilate the best points of all, for who can fail to see that the conception and practice of Handel, and indeed the very essence of his genius, was the absorption of a hundred different styles! "One of his manuscripts dated 1698, and preserved carefully all his life, contains," so says Chrysander, "some airs, choruses, capriccios, and fugues of Zachau, Alberti (Heinrich Albert), Froberger, Krieger, Kerl, Ebner, Strungk, which he had copied out whilst studying with Zachau." Handel could never forget these old masters, distinct traces of whom are found from time to time in his best-known works.[11] He would doubtless too, with Zachau, have seen the first volumes of the clavier works of Kuhnau, which were published at that time.[12] Moreover, it seems that Zachau knew the work of Agostino Steffani,[13] who later on took a fatherly interest in Handel; and Zachau followed sympathetically the dramatic musical movement in Hamburg. Thus the little Handel had, thanks to his master, a living summary of the musical resources of Germany, old and new; and under his direction he absorbed all the secrets of the great contrapuntal architects of the past, together with the clear expressive and melodic beauty of the Italian-German schools of Hanover and Hamburg.
