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.
