This was originally going to be a piano piece, but it progressed into something else because of experimentation. Then there was an error.

So it is not piano, and it is not particularly classifiable either, unless being a byproduct of an error warrants a label. I like it. It needs a plethora of refinements, especially towards the end where things become audibly muddy, but I like it nonetheless. I am attracted to the riff. It is what gives this piece its character. Everything else was built upon it, even the melody.
