so if I understand this correctly, the rotator would cause sparks as it 
turned, and depending on the speed of the rotations, you would get a higher 
or lower tone if you will based on the number of sparks being created?
So when you pressed down on the key, it would start creating sparks at a 
certain rate depending on the speed of the roter?
Essentially a spark generator?
