Here's a piece that I wrote last week after getting inspired by jonnylost's starting lesson on 20th century music. This is set up in a 12 tone matrix. Though I bent the rules a little in the second movement for a little more pleasing transition, the rest follows 12 tone rules as I understand them.
Give it a listen even if you're not into 12 tone music. I think you will find it interesting. There are 4 movements and they are all in the same mp3.

Thanks to all who listen.
