- 4-Note Rootless (Type A/B)
The Type B voicing of Cb7b9 stacks Bbb, C, Eb and Gb from the bottom up: the minor 7th, flat 9th, major 3rd and 5th of the chord. It leaves out the root, Cb, for the left hand or the bass player to take.
It's one of the 4-Note Rootless (Type A/B) voicings: four-note rootless voicings in their two forms, with the 3rd or the 7th on the bottom, played over the root. The other for Cb7b9 is Type A.
