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