Cb Minor 7, written Cbm7, is built from Cb, Ebb, Gb and Bbb: the root, minor 3rd, 5th and minor 7th.
Its 3rd and 7th, Ebb and Bbb, 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, Cbm7 is the iv7 of the Backdoor ii-V-I Progression in Gb.
