THE first circle on this diagram represents seven major key-notes, beginning with C on the third space in the treble clef, and sounding as their roots the seven last key-notes which have developed. The second is a continuation of the first circle. The seven previously developed key-notes are now the roots of seven higher key-notes. The intermediate notes are not coloured, but may be seen to be complementary pairs. [Harmonies of Tones and Colours, Diagram III - The Major Keynotes Developing by Sevens, page 25a]
