Answer 1

The earliest mention of the jal tarang is found in Vātsyāyana's Kamasutra as playing on musical glasses filled with water.[1] It is one of the 64 Arts and Science to be studied by a maiden.ref name="Vatsyayana"

In modern times, it has fallen into obscurity. Literally, jal tarang means "waves in water" but indicates motion of sound created or modified with the aid of water. In the wave-instruments, it is the most prominent and ancient instrument. This traditional instrument is used in Indian classical music. Some scholars think that in the ancient period these were in routine use around the eastern border of India.
