The life of Bach need not long detain us. A musician of the tenth generation, member of a family which occupies a liberal space in German encyclopedias of music, art and literature, Sebastian Bach led the life of a teacher, productive artist and virtuoso, mainly within the limits of the comparatively unimportant provincial city of Leipsic. His three wives in succession and his twenty-one children were the domestic incidents which bound him to his home. Here he trained his choir, taught his pupils, composed those master works which modern musicians try in vain to equal, and the even tenor of his life was broken in upon by very few incidents of a sensational kind. We do not understand that Bach was a virtuoso upon the violin, although no other master has required more of that greatest of musical instruments. Upon the piano and organ the case is different. Bach's piano was the clavier, upon which he was the greatest virtuoso of his time. His touch was clear and liquid, his technique unbounded, and his musical fantasy absolutely without limit. Hence in improvisation or in the performance of previously arranged numbers he never failed to delight his audience. It was the same upon the organ. The art of obligato pedal playing he brought to a point which it had never before reached and scarcely afterward surpassed. He comprehended the full extent of organ technique, and with the exception of a few tricks of quasi-orchestral imitation, made possible in modern organs, he covered the entire ground of organ playing in a manner at once solid and brilliant. Many stories are told of his capacity in this direction, but the general characterization already given is sufficient. He was a master of the first order. The common impression that he played habitually upon the full organ is undoubtedly erroneous. He made ample use of registration to the fullest extent practicable on the organs of his day.
