- Rootless 3-Note Shells
The Shell II voicing of Bb9sus4 stacks Ab, C and Eb from the bottom up: the minor 7th, 9th and 4th 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 Bb9sus4 is Shell I.
