Welsh composer and literary scholar. Born in Pembroke, he was a lifelong friend of Dylan Thomas - whose Collected Poems he ultimately edited. He read English at Swansea University before studying composition and conducting at the Royal Academy of Music, London and, on a Mendelssohn Scholarship, in Vienna. He then completed his university dissertation on "Elizabethan Lyric Poetry and its Relations with Elizabethan Music" (1939). His mature output included 12 symphonies, eight string quartets and the music for the original broadcast of Under Milk Wood. Though faithful to tonality, he experimented with complex metres as in his Sonata for Three Kettledrums (1947).
