- Rootless 3-Note Shells
The Shell I voicing of A#dim7 stacks C#, E and G from the bottom up: the minor 3rd, flat 5th and diminished 7th 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 others for A#dim7 are Shell II and Shell III.
