- 4-Note Rootless (Type A/B)
The Type B voicing of B#13 stacks A#, D, D## and A from the bottom up: the minor 7th, 9th, major 3rd and 13th of the chord. It leaves out the root, B#, 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 other for B#13 is Type A.
