Question

c Mention two ways to change the pitch of the sound
produced by the given instrument
guitar

Answer 1

Answer:

Guitar strings are tuned (tightened and loosened) using their tuning keys. Applying too much tension to a string tightly can raise it to the pitch of the next note, while loosening it can easily lower it the same amount. Increasing the tension raises the pitch. The length of a string is also important.

Answer 2

Tightening the string gives it a higher frequency while loosening it lowers the frequency. When string players tighten or loosen their strings, they are altering the pitches to make them in tune. The density of a string will also affect its frequency. Dense molecules vibrate at slower speeds.
