Answer 1

Answer:

Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies.

Answer 2

Explanation:

In music, the pitch of a note means how high or low the note is. In physics, it is measured in a unit called Hertz. A note that is vibrating at 256 Hz will be caused by sound waves that vibrate at 256 times a second. This will be Middle C on the piano. Not all musical instruments make notes of a certain pitch.
