- 4-Note Rootless (Type A/B)
The Type A voicing of Gbm6 stacks Bbb, Db, Eb and Ab from the bottom up: the minor 3rd, 5th, 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 Gbm6 is Type B.
