20th century American composer Paul Creston (1906-1985), born Giuseppe Guttoveggio, is known for his fidelity to older compositional styles. Largely self-taught, he credited Bach, Scarlatti, Chopin, Debussy, and Ravel as his greatest teachers. He wrote Principles of Rhythm and Rational Metric Notation and numerous articles analyzing the previous four hundred years of rhythmic practice.
