About
The Fsus4 chord (F–B♭–C) also replaces the third — this time with a perfect fourth. The fourth has a stronger gravitational pull than the second; in common-practice harmony it traditionally resolves downward to the third, making sus4 feel more like a delayed resolution than a neutral color. This makes it effective for rhythmic tension and release, especially in rock and gospel. The B♭ typically resolves to either F (third raised) or Fm (third lowered). On guitar the modification is often a single-finger addition or movement from a major shape; the fourth is the defining tone and must be present. Compared to Fsus2, sus4 has a clearer sense of wanting to land somewhere.
