The frequency of a pitch is derived by multiplying (ascending) or dividing (descending) the frequency of the previous pitch by the twelfth root of two (approximately 1.059463). [1] [2] For example, to get the frequency one semitone up from A 4 (A ♯ 4), multiply 440 Hz by the twelfth root of two.
The frequency data format allows for the precise notation of frequencies that differ from equal temperament. "Frequency data shall be defined in [units] which are fractions of a semitone. The frequency range starts at MIDI note 0, C = 8.1758 Hz, and extends above MIDI note 127, G = 12543.854 Hz.
The musical note frequency calculation formula is used: F=(2^12/n)*440, where n equals the number of positive or negative steps away from the base note of A4(440 hertz) and F equals the frequency. The formula is used in calculating the frequency of each note in the piece. The values are then added together and divided by the number of notes.
