This is just a remix of @ivan321's awesome project, so if you like this project, go tell him. I removed most of the buttons and interaction, and instead made it play music automatically. The chords are preset, but the melody is random. I also made some minor changes to the code, and tidied up a bit, but nothing substantial. I'm not sure what's up with the seventh string (second from the right) - it sounds off-key to me. I left it in, but the melody doesn't use it.
