About
The F♯sus4 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 F♯m (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 F♯sus2, sus4 has a clearer sense of wanting to land somewhere.
