PIANO KEYBOARD The number beside each …

PIANO KEYBOARD The number beside each key is the fundamental frequency in units of cycles per seconds, or Hertz. OCTAVES For example, the A4 key has a frequency of 440 Hz. Note that A5 has a frequency of 880 Hz. The A5 key is thus one octave higher than A4 since it has twice the frequency.
