Question

How different musical notes are produced in the instrument named Jal tarang.

Answer 1

This medieval musical treatise categories this instrument under Ghan-Vadya (Idiophonic instruments in which sound is produced by striking a surface, also called concussion idiophones.) SangeetSaarconsidered one with 22 cups to be complete jal tarang and one with 15 cups to be of mediocre status. Cups, of varying sizes were made of either bronze or porcelain. Today only china bowls are preferred by artistes, numbering around sixteen in normal use. Cups for Mandra Swar (notes of lower octave)are large while those for Taar Swar (notes of higher octaves) are smaller in size. Water is poured into the 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 bowls mostly are arranged in a half-circle in front of the player who can reach them all easily. The player softly hits the cups with a wooden stick on the border to get the sound. It's not easy to tune the instrument it needs some skill. During playing fine nuances can be reached if the performer is accomplished. SangeetSaar mentions that if the player can rotate the water through a quick little touch of the stick, nuances and finer variations of the note can be achieved.
