For some decades in the middle of the twentieth century, Paul Creston (1906–85) was one of the most frequently performed of American composers, though his music has sunk from prominence in recent years. He was himself a fearsome pianist, and his Three Narratives are Lisztian concert essays that require freewheeling virtuosity. Rhythmicon is a ten-volume collection of 123 brief studies that examine various aspects of rhythm. Their difficulty grows as the series progresses, reaching its zenith in Volumes 7–10, where Creston presents 25 studies that range in mood from serious to light-hearted, from hymn-like introspection and calm to jagged, Bartokian energy.
