Alois Hába
Alois Hába (21 June 1893 – 18 November 1973) was a
Czech composer,
music theorist and teacher. He belongs to the important discoverers in
modern classical music, and to the major composers of
microtonal music, especially using the
quarter-tone scale, though he used others such as
sixth-tones (e.g., in the 5th, 10th and 11th String Quartets),
fifth-tones (Sixteenth String Quartet), and
twelfth-tones. From the other microtonal conceptions, he discussed a "three-quarter tone" system (see
three-quarter tone flat and the
neutral second) in his theoretical works but he used scales in this tuning in sections of some of his compositions. In his prolific career, Hába composed three
operas, an enormous collection of
chamber music including 16
string quartets,
piano,
organ and
choral pieces, some
orchestral works and
songs. He also had special
keyboard and
woodwind instruments constructed that were capable of playing quarter-tone scales.
