उत्तर २
The spot where the stretched string is plucked is altered as an adjustment.
-
We are aware that when a string is forced to vibrate, it produces transverse waves with varying amplitude and frequencies. These can be altered by adjusting the location at which the string is plucking.
- middle
- `1/4`th part of string
- `1/6` is the part of a string to produce the principal tone, first subsidiary or second subsidiary, respectively.

-
Moreover, FREQUENCY can be altered by adjusting the string's thickness. By twisting the pegs on a string, the tension can also be altered.
