Piano improvisations by Curt Siffert. Unless otherwise noted, each piece is made up on the spot. Several have become very popular and have been used in many mixed-media works online. Visit http://curtsiffert.com/ for more music, and to see examples of paintings, movies, and other media produced in response to these songs. More art submissions always appreciated!
