I'm not sure exactly what you are looking for. Western musical semitones are spaced 2^(1/12) apart. The reference is normally the A above Middle C, which is specified as 440 Hz exactly. To find each higher semitone, multiply by 2^(1/12) once for each semitone. To find each lower semitone, divide by 2^(1/12) instead. Best regards, Bob Masta audioATdaqartaDOTcom
