(baptized Sept. 1, 1653, Nürnberg
died March 3, 1706, Nürnberg) German composer and organist.
Conservative musically, he was friendly with Dietrich Buxtehude and was the teacher of Johann Christoph Bach, who later gave lessons to his younger brother Johann Sebastian Bach . Though he wrote a huge amount of music, of which his organ chorale variations and Magnificat settings are especially remarkable, he is principally known today for a single piece, the extremely popular Canon in D Major , which he may not have written.
