- Rootless 3-Note Shells
The Shell II voicing of Bb13 stacks Ab, D and G from the bottom up: the minor 7th, major 3rd and 13th of the chord. It leaves out the root, Bb, 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 Bb13 is Shell I.
