- Rootless 3-Note Shells
The Shell I voicing of Abdim7 stacks Cb, Ebb and Gbb from the bottom up: the minor 3rd, flat 5th and diminished 7th of the chord. It leaves out the root, Ab, for the left hand or the bass player to take.
It's one of the Rootless 3-Note Shells voicings: three-note rootless voicings: the 3rd and 7th with one more tone, played over the root. The others for Abdim7 are Shell II and Shell III.
