Wow. Wikipedia's definition of the eigenharp hints at some really impressive control depth, including simultaneous pitch bend and modulation of each note. Mind-blowing.

I seriously youtube'd it after I found a hint at what it could be. It sounded pretty cool.

Ever heard of a Theramin?

Can't say that I have

Theremin actually, but I've never heard of this eigenharp thing, seems interesting.

Such is what happens when you use YouTube as a learning service.
