Sometimes unexpected projects appear in our inbox, like the Yaybahar, a purely acoustic stringed instument that sounds like a synthesizer. Görkem Şen, the instrument's creator, plays the instrument by hitting and stroking the horizontal cords with a mallet, plucking and strumming the vertical strings, and drumming on the feet. "Natural source coded materials which are membrane, coiled spring and string working together. Maybe we can say that this is a new bridge system between string and resonant body," explains director Olgu Demir in the video's description.
