(1920-2012) was a pianist whose lengthy career helped define the style of cool jazz. For most of his career, he led the eponymous Quartet named after him; the quartet's best known lineup, from the late 1950s through the 1960s, included Paul Desmond (sax), Eugene Wright (bass), and Joe Morello (drums). With this lineup, his quartet recorded the landmark 1959 album Time Out, which utilized non-traditional time signatures inspired by the folk music of Eastern Europe and Asia. The album's best-known track is "Take Five," a work in 5/4 time written by Paul Desmond. He continued to explore unusual time signatures on the follow-up albums Time Further Out (1961) and Time Changes (1964). His own notable compositions include "Blue Rondo a la Turk," which subdivides measures of 9/8 time into a "2+2+2+3" grouping.
