Unsquare Dance is a musical piece written by the American jazz composer Dave Brubeck in 1961.

Written in 7/4 time, the piece is a typical example of Brubeck’s exploration of time signatures. According to Brubeck, it was written during a single trip from his home to therecording studio, and was recorded the same day. Based on a blues form, the piece is driven by a strong bass figure, with percussion provided primarily by the rim of the snare drum and hand claps. It combines duple and triple meter. [source]
