A fascinating and most creative work!  Starting out in 2/4 meter, an eighth note is added to the meter of each successive movement (2/4, 5/8, 6/8, 7/8).  The melodies are very musical and dance-like, with touches of the familiar throughout, and some jazz harmonizations for good measure.  This marvelous work turns the math that you hated into the dance music that you love.
