★ Pitch

The shrillness of a sound is called its pitch. The pitch of a sound depends upon its frequency. Higher the frequency of a sound, higher is its pitch.

The voice of a child or a woman has higher frequency than the voice of a man.

♦ The faster is the vibration of the source object, higher is the frequency and therefore higher is the pitch.

♦ Higher pitch of any sound corresponds to larger number of compressions and rarefactions passing a point per unit time.

The stretched membrane of a tabla or mridangam produces sound of a higher frequency (or of higher pitch).
