William Sweeney

Born in Glasgow, he attended Knightswood Secondary School. He studied the clarinet and composition at the Royal Scottish Academy of Music and Drama from 1967 to 1970, and at the Royal Academy of Music from 1970 to 1973, where his teachers included Alan Hacker and Harrison Birtwistle. He went on to teach woodwind instruments, and then composition at the University of Glasgow. An early influence was the European avant-garde, particularly Karlheinz Stockhausen, though he returned to tonal composition in the mid-1970s. His work is strongly influenced by traditional Scottish folk music; in particular, he has utilised the heterophonic style of Gaelic psalm-singing, and the piobaireachd form; he varies melodies through ornamentation, as in traditional pibroch, and in their contour; he modifies instruments' tone-colours through alternative fingerings. He has a strong regard for the music of Leoš Janáček. He has also addressed the reconciliation of classical and traditional music with jazz, using improvisational techniques and sometimes combining the two idioms. He has been influenced by ancient Greek poetry, and Indian and Arab traditions in his use of ostinato and other techniques of varied repetition. His Sonata for cello and piano (2010) won the 2011 British Composer Award in the "Instrumental Solo or Duo" category.
