- CbM3Ebm3GbM3Bb
Cb Major 7, written Cbmaj7, is built from Cb, Eb, Gb and Bb: the root, major 3rd, 5th and major 7th.
Its 3rd and 7th, Eb and Bb, 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, Cbmaj7 is the IVmaj7 of the Minor Plagal Cadence in Gb.
