About Fsus4
Fsus4 is built from three notes: F (root), Bb (perfect fourth) and C (perfect fifth). Its interval formula is 1 – 4 – 5. With no third, the perfect fourth asks to resolve; it is very common right before the major or minor chord on the same root.
Fsus4 has no standard open shape in the CAGED system, so its 21 voicings are sorted only by difficulty and position on the neck.
