- Rootless 3-Note Shells
The Shell I voicing of Ab7 stacks C, Gb and Bb from the bottom up: the major 3rd, minor 7th and 9th 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 other for Ab7 is Shell II.
