(b Vizovice, 21 June 1893; d Prague, 18 Nov 1973). Czech composer. He played in his father's folk band and studied with Novák at the Prague Conservatory (1914-15) and with Schreker in Vienna and Berlin (1918-22), though he was influenced more by Schoenberg in developing an athematic, highly chromatic style. A suite for strings (1917) was his first work to use quarter-tones, which became a sphere of interest and which he used in his opera The Mother (1931). He taught microtonal composition at the Prague Conservatory (1924-51) and wrote choral music, 16 string quartets and much else using quarter-tones and sixth-tones.
