Vincent, Heinrich Joseph
Born at Theilheim, near Wurzburg, and died in Vienna. First a student of theology and then of law, he abandoned both to become a tenor singer in Vienna, Halle and Wurzburg. In 1872 he became a teacher of singing at Czernowitz, Bukowina, and a leader of the singing society there. Eventually he lived in Vienna. He composed several operas and operettas and a number of songs. He published the pamphlets, Kein General-bass mehr, Die Einheit in der Tonwelt, Die Neuclaviatur, and a series of articles on the chromatic keyboard and notation in several periodicals. He was a staunch advocate of the Chroma Society twelve-halftone-system.
