- Rootless 3-Note Shells
The Shell I voicing of A#9sus4 stacks D#, G# and B# from the bottom up: the 4th, minor 7th and 9th of the chord. It leaves out the root, A#, 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 A#9sus4 is Shell II.
