realistic character, and in general he shows himself in his piano works a man of wide range of mind and extremely vigorous musical fantasy. In the department of concertos for solo instruments and orchestra, his works are very rich. There are a large number for piano, quite a number for organ, several for two and three pianos, with orchestra, and various other combinations of instruments, such as two violins and 'cellos, and so on. In these each solo player has an equal chance with the other, and solos and accompaniment work together understandingly for mutual ends. The most noticeable feature of his elaborate works is the rhythm, which is vigorous, highly organized and extremely effective. In the department of harmony, it is believed by almost all close observers that no combination of tones since made by any writer is without a precedent in the works of Bach; the strange chords of Schumann and Wagner find their prototypes in the works of this great Leipsic master. Melodically considered, Bach was a genius of the highest order. Not only did he make this impression upon his own time and upon the great masters of the next two generations, but many of his airs have attained genuine popularity within the present generation, and are played with more real satisfaction than most other works that we have. This is the more remarkable because from the time of his first residence in Leipsic when he was only twenty-four years old he went out of that city but a few times, and heard very little music but his own. He was three times married, and had twenty-one children, many of whom were musical. Three of his sons became eminent, and the principal episode of his later life was his visit to Potsdam, where his son, Carl Phillip Emanuel, was musician to Frederick the Great. Here he was received with the utmost informality by the king and made to play and improvise upon all the pianos and organs in the palace and the adjacent churches. As a reminiscence of this visit he produced a fugue upon a subject given by Frederick himself, written for six real parts. This work was called the "Musical Offering," and was dedicated to Frederick the Great. In his later years Bach became blind from having over-exerted his eyes in childhood and in later life. He died on Good Friday in 1750. CHAPTER XXIV. GEO. FREDERICK HAeNDEL.
