About the score - It does need a lot of cleaning, I definitely just finished putting in what I had and uploaded it. I've been working on it non-stop this last week, so I was kinda like....done for now.
About the form of the piece - Initially I had the first few minutes, then some other, more rhythmic stuff in the middle, and then the ending (from 5:20 on). However, the 'B' section wasn't working at all, and I had to rework it a lot. I basically had three rhythmic shapes and motifs for this - the intro rhythm, which is present the most, followed by the eighth notes (up down up down, with grace notes) and then the theme that comes in the 'B' section (that sounds like it's in Dorian mode). The A section is the first two, the 'B' section is the third, and the rest is all three interloped.
I could see how it could get tiring. I think with actual performers it will be okay. Before I had finished the 'B' section I felt like I would need a more obvious return to the 'A' material, but having finished the 'B' section I feel that it feels complete on its own.
But I've also spent the last week immersed in the piece, so I'm a little biased.
Thanks for your comments man.
