Each 11×17 sheet becomes one of the keys. I used aluminum foil to make a large conductive area, and copper tape to connect the foil to the alligator clips.
Set the six keys in a row, and tape to the ground. Add black construction paper to represent the black keys.
Connect to the Makey Makey using the alligator clips, and load the the Makey Makey piano app. If you have never used Makey Makey before, the How To page is a great introduction.
Tips:
It did work with shoes on, but there was more wear and tear on the keys.
A lot of kids wanted to just use their hands.
It’s a big leap to play Twinkle Twinkle Little Star.
