Musicalified

Hey - enjoyed the project so I added a bit of harmony. It now plays weeks as if they were major chords (with some spice), and can even put a bit of feeling into it. Essentially, not two plays are identical.

I've left some config in there that can be played about with, perhaps they could be exposed to the user, including a set of minor notes that you might enjoy!

Anyway, hope you like it.
