Which term describes a tone's experienced highness or lowness?

The term that describes a tone's experienced highness or lowness is pitch. Pitch refers to our perception of sound frequencies; higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches. This auditory perception is crucial in distinguishing different sounds, such as musical notes or the tones of voices.

Volume, on the other hand, relates to the loudness or intensity of a sound, which is not the same as pitch. Frequency measures the rate of sound wave vibrations, which contributes to the pitch but is a more technical term that quantifies sound rather than describing perception. Height is not a commonly used term in music or sound perception and can cause confusion as it does not accurately describe the auditory experience as pitch does.
