In this image set the twelve pitch classes are numbered like piano keys modulo 12.
A is the lowest key on the piano keyboard and thus labelled 1.
(Piano key frequencies)
This way the circles of numbers and letters are aligned:
The 0 is between the first letter A and the last letter G,
and the middle letter D corresponds to the middle number 6.
The numbers 10 and 11 are represented by the dozenal digits created by W. A. Dwiggins,
which are used by the Dozenal Society of America. (Duodecimal Bulletin from 2008)
