Although born Giuseppe Guttovergi to a poor, immigrant Italian family, it was as Paul Creston that Giuseppe rose to prominence, becoming one of the most widely performed American composers. Rhythm was a continued subject of research for this composer, and by 1945 he had established a terminology of rhythmic structures, which he observed both in his music and the music of other composers, even writing two books on the subject. This volume presents for the first time a complete descriptive account of the life of the composer, as well as access to currently available materials by and about him.
