This tune is called "Joy to the Beat". In this episode of "Make it do music" I hacked our Christmas tree to play a music. A TREE-board if you will !!!! the most difficult part was finding Bobbles that were conductive. Most of them are made out of glass!! Also, things get progressively more Christmassy. This is the consequence of playing this instrument!!!!
Used in this project:
Adafruit Capacitive touch hat
