Rootless 7♭9 voicings on guitar

Rootless 7♭9 (3–5–♭7–♭9). As a close stack it spans more than a hand, so it is played as drop 2 of each inversion. Practice Lab's voicing search finds 12 shapes, every one movable: drawn here on C (E, G, B♭, D♭), each plays any key moved to it, as the table below shows.
