- 4-Note Rootless (Type A/B)
The Type A voicing of F#7alt stacks A#, C##, E and A from the bottom up: the major 3rd, sharp 5th, minor 7th and sharp 9th of the chord. It leaves out the root, F#, 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 F#7alt is Type B.
