Johann Michael was the son of Johann Elias Bach and a descendant of a specific line of the Hessian Bachs. His work as an organist avocationally brought him to the position of Kantor in Tann. "Kurzs und systematische der Tonkunst uberhaupt" was his primary contribution to the musical world and a few compositions (concertos and cantatas) are to his credit. ~ Keith Johnson, Rovi
