Yaybahar by Görkem Şen from Olgu Demir on Vimeo.
This brainchild of Görkem Şen is certainly percussion, but it's also melodic and can be played with a bow. It's resonant and totally awesome. To me it sounds like whalesong. If whales played strings. And drums. And didgeridoos.
The Yaybahar is described on Vimeo thusly:
"Yaybahar is an electric-free, totally acoustic instrument designed by Gorkem Sen. The vibrations from the strings are transmitted via the coiled springs to the frame drums. These vibrations are turned into sound by the membranes which echo back and forth on the coiled springs. This results in an unique listening experience with an hypnotic surround sound.There's a website, http://yaybahar.com, which contains nothing but this video and a single link to the email address: email@example.com
What you hear in this performance is captured in realtime without any additional effects and with no post audio processing."
