- 4-Note Rootless (Type A/B)
The Type B voicing of A#dim7 stacks G, B#, C# and E from the bottom up: the diminished 7th, 9th, minor 3rd and flat 5th of the chord. It leaves out the root, A#, for the left hand or the bass player to take.
It's one of the 4-Note Rootless (Type A/B) voicings: four-note rootless voicings in their two forms, with the 3rd or the 7th on the bottom, played over the root. The others for A#dim7 are Type A and Type C.
