What does the term "pitch" refer to in sound?

The term "pitch" refers to how high or low a sound is perceived to be. It is a fundamental characteristic of sound that allows us to distinguish between different musical notes and voices. Pitch is determined primarily by the frequency of the sound waves; higher frequencies produce higher pitches, while lower frequencies result in lower pitches. Essentially, pitch is what enables us to identify whether a sound is a high note or a deep tone, giving it a critical role in music, speech, and various auditory experiences.
