- 4-Note Rootless (Type A/B)
The Type B voicing of Cdim7 stacks Bbb, D, Eb and Gb from the bottom up: the diminished 7th, 9th, minor 3rd and flat 5th of the chord. It leaves out the root, C, 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 others for Cdim7 are Type A and Type C.
