I am not a musician, as close as I get to making music is Rock Band. I can only imagine how much time it would take to learn an instrument like the piano or guitar that have been around for ages, much less learning to play a brand new type of instrument like the Eigenharp.
The Eigenharp is a strange cross between a wind instrument, a keyboard, and a string instrument. Two versions are offered including the Pico and the Alpha. The Alpha versions is a full-size concert version of the device and the Pico is a small handheld version.
