The yazh (Tamil: யாழ், also transliterated yāḻ) is a harp used in ancient Tamil music which was the ancestor of modern-day veena. It was named so, because the tip of stem of this instrument was carved into the head of the mythological animal Yali. The yazh was an open-stringed polyphonous instrument, with gut strings (narambu) with a wooden boat-shaped skin-covered resonator and an ebony stem.
