Schoonenbeek taught at the latter institute from 1975 till 1977, where he also won the Composition award in 1978. Before he returned to Tilburg in 1980 he taught at the university of Amsterdam at the music faculty. As a composer Schoonenbeek makes use of sound idioms which are accessible to a large audience. His compositions are very diverse and include, besides chamber music, works for choir, orchestra and wind ensembles.
