I had nothing but final projects my last semester at Cornell, and my composition class was no exception. I had a tough time deciding what exactly to write, but I finally settled on using a song from Majora's Mask as part of my theme and worked from there. Specifically, I took the first 10 or so notes from the melody of this song and stretched them out over a longer timespan
We had our pieces performed by (mostly) faculty of the department in a quasi-concert. Below is the part of my piece that they were best able to play (which is also the main melody taken from MM):
There were a number of issues with the piece that prevented the players from performing better, chief among them the fact that the piece is in G# minor. Other problems included hard-to-read enharmonic spellings and rest rhythms. Also towards the end, the piano part becomes virtually impossible to play. You can check out the score to see what I mean (pdf).
If it were going to be performed again, these issues would be pretty easily remedied by rewriting the piece in a different key. Luckily midi doesn't have some of the problems human performers do, so I put a midi representation of the score if you're interested in hearing the piece in its entirety.
