Pitch (music)

Pitch in music refers to the perceived frequency of a sound, which determines how high or low a note sounds. It is a fundamental characteristic of musical notes and is crucial for the creation of melodies and harmonies. Pitch is typically measured in Hertz (Hz), which represents the number of vibrations or cycles per second. For example, the standard pitch for the note A4 (the A above middle C) is set at 440 Hz.
