The Jal Tarang Jaltarang, Jal-tarang, Jal-yantra, Jalatarangam or Jalatharangam, is an Indian melodic percussion instrument

Percussion instrument

A percussion instrument is any object which produces a sound when hit with an implement or when it is shaken, rubbed, scraped, or otherwise acted upon in a way that sets the object into vibration...

. It consists of a set of ceramic bowls tuned with water. The bowls are played by striking the edge with beaters, one in each hand.

It is rarely seen or heard, even though the gentle tinkle of its unique sound is quite pleasing. Literally, jal tarang means "waves in water" but indicates motion of sound created or modified with the aid of water.
