F#7sus4
A sus4 triad plus a minor 7th: root, perfect 4th, perfect 5th, minor 7th. No 3rd means no tritone — the drive comes from the stacked 4ths inside.
How does f# dominant 7 sus 4 sound?
Modern and modal — the bite of a dominant with the 3rd removed. It pushes like a V7 but stays cool and unresolved, more hallway than doorway.
A dominant that delays (or refuses) resolution: G7sus4 → G7 → C is gospel's favorite cadence; keeping it unresolved is the sound of 70s fusion and modal jazz.
Where do you use F#7sus4?
Hold F#7sus4 where a F#7 would go (the V of B) and resolve it late — or never: gospel and fusion ride the sus color for whole sections before releasing into B.
F# sits almost entirely on black keys — it looks intimidating on paper and lies surprisingly well under the hand once you trust the short keys.
Herbie Hancock comping, gospel "back-cycling", the Rhodes chord of a thousand soul intros — and modern pop bridges that want motion without commitment.
How do you finger F#7sus4 on piano?
Root-4th-5th-♭7 spreads evenly: 1-2-3-5 with the index on the 4th. The quartal spacing keeps every finger on its own comfortable perch.
The root is a black key — let the longer fingers (2, 3) own the black notes and keep the thumb toward the white keys where the shape allows.
Tip: the common mistake
Sneaking the 3rd in underneath. The moment the 3rd sounds, it is an ordinary dominant — the whole point of 7sus4 is the missing tritone.
