Hoffmann, Bruno, German glass harmonica player and composer; b. Stuttgart, Sept. 15, 1913; d. there, April 11, 1991. He studied piano, organ, and voice. In 1929 he became interested in building a modern “glass harp” and eventually expanded its range to 4 octaves, covering a full chromatic scale. With this instrument, he gave concert tours in Europe (from 1949), Asia (from 1962), the U.S. and Canada (from 1964), and South America (from 1969). He also composed a number of works for the glass harp.
