About
The F♯7sus4 (F♯–B–C♯–E) combines dominant function with suspended ambiguity. The B replaces the third, delaying the chord’s major/minor identity, while the E signals dominant territory. Resolution typically happens in one of two ways: the 4th resolves down to the 3rd, producing a standard F♯7; or the chord resolves directly to the tonic (B), skipping the third entirely. The 4th and ♭7 are both essential — the 4th is the suspension, the ♭7 the dominant weight. The 5th can be omitted. Compared to plain F♯sus4, 7sus4 has clear harmonic direction; compared to F♯7, it is less declarative.
