This instrument was made by shaman, sound healer, and master wood carver Agustin Rivas. He calls it a Fairy's Bow, or El Arco del Duende. It makes incredibly subtle and rich harmonic overtones. It sounds like it plays between all the dimensions - a rainbow of sound.
It was gifted to me, by a totally magical sequence of events. One of them being that I understand how to move the muscles in my face in great detail, as an experimental vocalist, so I can really play the harmonics. I am in awe of the powerful shamanic tools, instruments, and protective garments that I have been gifted to do my work in the world and be safe. They all have unbelievable stories behind them.
When I first received this instrument, I could barely hold its power. The first time I visited Grass Valley, I was sitting at the bus stop with this, and a guy walked by and said "is that a mouth harp? you need a super cardioid microphone if you want to play that in a band", so it picks up only the close-up subtle sounds and not the other instruments around. I haven't tried that yet.
I don't even know if I'm playing it right - if anyone else has one of these and can teach me how to get the harmonics to project louder, please let me know!

A friend of mine shared this video with me, with a killer berimbau solo at 16:30 in. I <3 the 70's.
