David Warren Brubeck (born December 6, 1920 in Concord, California), better known as Dave Brubeck, is an American jazz pianist. 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 Dave Brubeck Quartet's most famous piece, "Take Five", which is in 5/4 time and has endured as a jazz classic. 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. He also provided music for the TV animated miniseries "This Is America, Charlie Brown".
