Yaybahar is an acoustic musical instrument invented by a Turkish musician Gorkem Sen (Turkish: Görkem Şen), who describes it as a "real-time acoustic string synthesizer." In its online review, Classic FM called yaybahar a "genius monstrosity" that makes "thoroughly bizarre, terrifying and delightful noises." Journal of Music describes the sound of yaybahar as "completely enthralling."

The name yaybahar has Turkish origin. It is a composite of two words: yay means a "string" or a "coiled string" and bahar translates into English as "spring." In one of the interviews Gorkem Sen states that the name is derived from the idea of a new life or a new beginning.
