To make the practical on jaltarang musical instrument

Answer 1

Jal Tarang or the "jalatharangam" is an Indian melodic percussion instrument. It consists of a set of ceramic or metal bowls filled with water and these bowls are played by striking the edge with wooden beaters or Japanese bamboo sticks, one in each hand.

Cups of varying sizes were made of either bronze or porcelain. However, nowadays only china bowls are preferred by the artists. Around sixteen cups are normally used.

Cups for Mandra Swar (notes of the lower octave) are large while those for Taar Swar (notes of higher octaves) are smaller in size. The bowls are usually arranged in a semi-circle in front of the player to reach them all easily.

Water is poured into these cups and the pitch is changed by adjusting the volume of water in the cup. The number of cups depends on the melody being played. The player softly hits the cups with a wooden stick on the border to get the sound.
