David Warren Brubeck (born December 6, 1920), known as Dave Brubeck, is an American jazz pianist. 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. His music is known for employing unusual time signatures, and superimposing contrasting rhythms, meters, and tonalities.

His long-time musical partner, alto saxophonist Paul Desmond, wrote the Dave Brubeck Quartet's best remembered piece, "Take Five", which is in 5/4 time and has endured as a jazz classic. Brubeck experimented with time signatures throughout his career, recording "Pick Up Sticks" in 6/4, "Unsquare Dance" in 7/4, and "Blue Rondo à la Turk" in 9/8. He is also a respected composer of orchestral and sacred music, and wrote soundtracks for television such as Mr. Broadway and the animated miniseries This Is America, Charlie Brown.

Brubeck was born in Concord, California. His father was a cattle rancher, and his mother, who had studied piano in England and intended to become a concert pianist, taught piano for extra money. Brubeck originally did not intend to become a musician (his two older brothers, Henry and Howard, were already on that track), but took lessons from his mother. He could not read sheet music during these early lessons, attributing this difficulty to poor eyesight, but "faked" his way through, well enough that this deficiency went mostly unnoticed.
