- CbM3Ebm3Gb2Ab
Cb Major 6, written Cb6, is built from Cb, Eb, Gb and Ab: the root, major 3rd, 5th and 6th.
Its 3rd and 6th, Eb and Ab, are its guide tones: they say what kind of chord it is, so voicings are built around them and the root is often left to the bass.
In the progressions here, Cb6 is the IV6 of the Rhythm Changes in Gb.
