Which one of the following methods is adopted for perfect tuning of Jal Tarang?

Correct option is C

Correct Option: c)
Jal Tarang is an Indian melodic percussion instrument consisting of ceramic or porcelain bowls filled with water. The pitch produced by striking a bowl is determined by the volume of air inside it that can vibrate.
Information Booster:
· The pitch of each bowl in the Jal Tarang is tuned by adjusting the quantity of water in it.
· Adding water raises the pitch (as the air column shortens), and removing water lowers the pitch (as the air column lengthens).
· This is the primary and essential method for achieving the correct musical scale across the set of bowls.
Additional Knowledge:
· While the size and thickness of bowls are fixed when selected for an instrument set, they are not adjusted during tuning for a performance.
· Adding heavy matter to the water would dampen the vibration and affect the tone quality, not provide accurate pitch control.
