1. Find all the piano keys that make a light turn on.
From left to right:
2nd white key = 1st light
Last white key = 2nd light
8th black key = 3rd light
2nd black key = 4th light
6th black key = 5th light
4th black key = 6th light
Now you have to turn on each light in order from left to right (1 to 6).
Depending on the device, all the lights may have to be on at the same time and in the correct order.
