Characteristic of Sound - 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).
