Impulse Tracker doesn't use traditional musical notation; instead, it divides measures up into fairly arbitrary time periods, and you can place notes within those time periods. For this one I set the time divisions to be 1/5, 1/25, and 1/125 of a measure, and composed a jazz song on it. Little did I know that this song bears an uncanny rhythmic resemblance to Take Five by Dave Brubeck! So everyone thinks I ripped him off, and also think I'm clueless about music theory (which I studied fairly intensely once upon a time) because there's "no such thing as 5/5 time, surely you mean 5/4" and so on. Oh well, I still like it.
This was also an entry into hornet.org's Music Contest 5 (the numerical connection being a coincidence). It came in 12th place in the intermediate division. For a while I had that awesome achievement listed on my resumé.
