I wrote this piece with one intention: Make 17/8 time sound good, or at least passable.
So I came up with this. Is it playable? Probably not, unless you omit some of the notes. Does it make sense? Maybe. Was it fun to create? Absolutely!
Oh, and it also sounds surprisingly good on a marimba. You can check it out here:
