The term kemenche (Turkish: kemençe, Greek: κεμεντζές) is used to describe two types of three-stringed bowed musical instruments:
- a bottle-shaped lute closely related to the Cappadocian Kemane, found in the Black Sea region of Asia Minor, it is also known as the "kementche of Laz" or Pontic kemenche and
- a pear-shaped lute closely related to the Byzantine lyra, found mainly in Instabul and the Eastern regions of Turkey, known as Classical kemenche.
Both types of kemenche are played in the downright position, either by resting it on the knee when sitting, or held in front of the player when standing. It is always played "braccio", that is, with the tuning head uppermost. The kemenche bow is called the doksar (Greek: δοξάρι), the Greek term for bow.
