He made a new instrument. The sound that first escaped his lips after he did so was what he named it. Meet Mr. Gorkem Sen and ‘Yaybahar’, a musical instrument created by this man. The 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 a unique listening experience with an hypnotic surround sound.” as is mentioned on Sen’s online bio.
Hypnotic could be the correct word to use here, for his instrument sounds a lot like a mix of water splashes and bomb explosions, yet with the subtle psychedelic feel.
