In music and acoustics, pitch refers to the perceived highness or lowness of a sound. It's determined by the frequency of the sound wave: higher frequency means higher pitch, and lower frequency means lower pitch.

In sports like baseball or cricket, a pitch is the act of throwing the ball towards the batter or batsman.

A pitch can also refer to the playing field itself (especially in British English), like a football pitch.

A pitch is a persuasive speech or presentation used to convince someone to buy a product, invest in a business, or accept an idea.

Pitch can also describe the angle or slope of something, like the pitch of a roof.

There are also some other, less common meanings, such as a type of dark, sticky resin or to set something up (like a tent).
