- 4-Note Rootless (Type A/B)
The Type A voicing of Bb7sus4 stacks Eb, F, Ab and C from the bottom up: the 4th, 5th, minor 7th and 9th of the chord. It leaves out the root, Bb, 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 Bb7sus4 is Type B.
