David Warren "Dave" Brubeck was an American jazz pianist and composer, considered to be one of the foremost exponents of cool jazz. He wrote a number of jazz standards, including "In Your Own Sweet Way" and "The Duke". Brubeck's style ranged 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 saxophone melody for the Dave Brubeck Quartet's best remembered piece, "Take Five", which is in 5/4 time and has endured as a jazz classic on one of the top-selling jazz albums, Time Out. Brubeck experimented with time signatures throughout his career, recording "Pick Up Sticks" in 6/4, "Unsquare Dance" in 7/4, "World's Fair" in 13/4, and "Blue Rondo à la Turk" in 9/8. He was 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.
