Time Changes is a 1964 album by The Dave Brubeck Quartet, based upon the use of time signatures that were unusual in jazz music.

The whole second side of the album, the composition "Elementals", resulted from a relationship with Rayburn Wright, The Eastman School of Music and its "Arranger's Workshop" and an impending concert in Rochester, New York.

On the original vinyl LP: All pieces composed by Dave Brubeck, except "Shim Wha" by Joe Morello.

The album was recorded over various sessions that took place in November 1963.
