"David Warren Brubeck" (born December 6, 1920 in Concord, California), better known as "Dave Brubeck", is a U.S. jazz pianist. Often regarded as a genius in his field, he has written a number of jazz standards, including "In Your Own Sweet Way" and "The Duke". Brubeck's style ranges from refined to bombastic, reflecting his mother's attempts at classical training and his improvisational skills. Much of his music employs unusual time signatures.
His long-time musical partner, alto saxophonist Paul Desmond, wrote the quartet's most famous piece, "Take Five", which is in 5/4 time. Brubeck experimented with time signatures through much of his career, recording "Pick Up Sticks" in 6/4, "Unsquare Dance" in 7/4, and "Blue Rondo à la Turk" in 9/8, an experimentation begun with his attempts to put music to the odd rhythms generated by various machines around him on his parents' cattle ranch in a small town in the western United States.
