To calculate frequencies of musical notes from known standard (88-key) piano note number n p and the standard pitch A440, and vice versa, we can use the following formulas: There are 128 notes in the MIDI standard (0 to 127), from the note C–1 (minus 1), which is the MIDI note 0 with a frequency of 8.176 Hz, to the note G9, which is the MIDI note 127 with a frequency of 13289.750 Hz. To calculate frequencies of musical notes from known MIDI note number n m and the standard pitch A440, and vice versa, we can use these formulas: The formula above can be modified to calculate the number n of semitones away from the standard pitch f 0: N is the number of semitones (half steps) from the standard pitch n > 0 for notes higher than the standard pitch, and n < 0 for notes lower than the standard pitch. It is usually a standard (also called concert) pitch of 440 Hz, which is called A440 or note A in the one-line (or fourth) octave (A4) The basic formula to calculate frequencies of musical notes of the equal-tempered scale:į n is the frequency of the note, which is n semitones (or half steps) away from the standard pitch A440 į 0 is the frequency of a fixed note, which is used as a standard for tuning.
