How does jaltarang produce different notes?

Jaltarang produces different notes by varying the amount of water in each ceramic bowl, which alters the pitch of the sound produced when the bowls are struck with mallets. Each bowl is tuned to a specific note, and by adjusting the water level, musicians can achieve precise pitches. Additionally, the size and thickness of the bowls also contribute to the tonal quality and resonance of the notes played. This combination of factors allows for a wide range of musical expression within the instrument.
