I would like to share with you a George Harrison piece. "While My Guitar Gently Weeps" performed by Bob Culbertson
Whilst Harrison gave the title to the song “While My Guitar Gently Weeps, this is the next step from the guitar which sings beautifully.
Emmett Chapman invented this instrument way back in the early ‘70s I cannot imagine why I haven’t heard anything about it before having been an avid guitarist since I could pick one up
It is classified as a composite chordophone (Hornbostel-Sachs classification 321.322;(composite chordophone) but known as a Chapman stick.
Here is another example for you to listen to: Chapman Stick - Carol of the Bells - Greg Howard
If you would like to know more about the Chapman Stick listen to the inventor explaining further
