Music Theory QuickThink:

COMMON TONE THEOREM – If you look at the Interval-class-vector , the # in each labeled position tells you how many common tones will appear between the original set and the resulting set when transposed by the labeled position # and the original set. For IC VECTOR 060603  ,if you transposed the set by 2, you would have 6 common tones between the original set and the resulting set.  (for spot 6, you have to double the number to get the number of common tones)

Transpositions number larger than 6 simplify to the number that adds to 12. (Example, 9 simplifies to 3. 8 simplifies to 4)
