Question

when a pair of tabla is struck one of the instrument produces sound of high pitch and other one produces sound of low pitch ​

Answer 1

Answer:

the difference in tension of the leather membrane

Explanation:

The top of the tabla drum is covered with a stretched, layered leather membrane held in place by leather braces. The wooden pegs between the braces and the drum adjust the tension in the braces, thus controlling the pitch of the instrument.

Hence, to increase the pitch of the sound produced the player tightens the skin by stretching the string around it.
