- Rootless 3-Note Shells
The Shell I voicing of Gbm7b5 stacks Bbb, Dbb and Fb from the bottom up: the minor 3rd, flat 5th and minor 7th of the chord. It leaves out the root, Gb, 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 other for Gbm7b5 is Shell II.
