- Rootless 3-Note Shells
The Shell I voicing of G9sus4 stacks C, F and A from the bottom up: the 4th, minor 7th and 9th of the chord. It leaves out the root, G, 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 G9sus4 is Shell II.
