- The highness or lowness of a sound. It is determined by the frequency (Hz); higher frequencies result in higher pitches, and lower frequencies in lower pitches.
- Frequency (Hz)
- A unit expressing the number of sound wave vibrations per second. Hertz (Hz). The note A4 is commonly defined as 440 Hz.
