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.
