"This is a song that I wrote over the course of an afternoon. It's mostly impromptu (hence the "Expulsion" in the title) and made as a test for the software I have at my disposal. I don't know how to play piano (lacking technique or theory) as I'm a mostly self-taught guitarist."

The quote is taken from the description on the video itself, back from when it was created and posted June 8th, 2012. Needless to say since then I have learned a lot. Not necessarily with regards to piano technique. But mine is an endless journey.
