crawlspace.mp3 - length 3:16, size: 3 MB

The plain 19-37 fragment contained two primes I didn't need for Crawlspace: 31 & 37. For some reason, I didn't seem to need 33, either, even though its the 3:2 of 22, and 22 occurs frequently enough. I did need the 3:2s of 30 & 34, so I added 45 & 51. The ostinato pattern required 53 in order to feel right.

There are 10 primes represented. The largest step size is 112 cents, and the smallest is 32. All step sizes are unique.

Crawlspace was written as creepy background music for custom levels of the classic computer video game, DooM.
