The pitch of a jaltarang bowl depends on its water level. More water lowers the pitch, while less water raises it. Different water levels create various notes, allowing for a full musical scale.

Class 6 Visual Arts Kriti-I musical instruments question answer
In a jaltarang, the amount of water in each bowl directly affects its pitch. A bowl with more water produces a lower-pitched sound, while one with less water generates a higher pitch. This principle follows the concept of vibration frequency—water volume influences the sound waves produced when the rim is struck. By adjusting the water levels in different bowls, musicians can create a full range of musical notes, allowing them to play melodies and scales effectively.
