I wasn't surprised to learn that Gigi Gryce (short for George General Gryce), the saxophonist and bandleader who wrote the pocket-sized jazz standard masterpiece called "Minority", studied classical composition (at the Boston Conservatory during the forties), because it is a perfect example of the small compositional form known as "sentence structure". In it, a melodic idea is played, then repeated in a contrasting key and then "liquidated", which according to Arnold Schoenberg's Fundamentals of Musical Composition, consists of "gradually eliminating characteristic features, until only uncharacteristic ones remain, which have little in common with the basic motive". Here's a version, performed by an all-star lineup, in which the form is clearly audible: http://www.youtube.com/watch?v=EDR2c6k9ixk&feature=related. The theme is played twice at the beginning, the first starting at 0:14, and the second at 0:29. (By the way, you'll hear sentence structure in a great many of Mozart's works, as well, if you listen for it.)
