- 4-Note Rootless (Type A/B)
The Type A voicing of Gbmb6 stacks Bbb, Db, D and Ab from the bottom up: the minor 3rd, 5th, flat 6th and 9th of the chord. It leaves out the root, Gb, 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 Gbmb6 is Type B.
