Answer 2

The correct answer is (a) tightening the string.

The sound frequency of musical instruments can be controlled by changing the settings of the strings. When the string of an instrument is stretched between two point, the tightened strings produce tension. Here, tension refers to how tightly the string is being stretched. Tightening of the string provides higher frequency. The higher frequency vibrations are carried to ear which considers high frequency as high pitch.
