Thanks! I think right now it jumps between the variation too quickly.. it feels schizophrenic? So for the next draft, I'll work on spending more time on each variation. Also, I am working on shaping the whole piece so there's a clearer structure--intro, variations, climax, coda.. something like that.
I did try to "smooth" out the transitions between the sections by referencing previous sections. For example, the beginning of the 3/4 section (bar 13) condenses the melody from the previous section (bar 9-12). Then the beginning of the 2/4 section (bar 24) has waltz-y chords overlayed with the 2/4 rhythm.
Another concern is that it gets too academic in places. The piece up to the high point (starting at bar 47) is basically condensing the chords. It starts as one chord change per measure in 4/4, then chord change every 3/4 measure, then 2/4. Then back to 4/4 but double time. Then at bar 43 each 1/16th note actually follows a rough I-vi-IV-V pattern, while each measure also follows the pattern. That's so it goes from really condensed chord progressions back to progressions spanning larger sections of the piece. Very academic, right? The feel I'm going for is faster-faster-faster up to the high point, and then gradually calm down.
