How to play Fsus4 on piano
Start with the notes in root position from low to high: F – B♭ – C. Right hand 1–3–5; left hand 5–3–1 is a useful starting point, but black-key combinations and melodic movement may make another fingering more comfortable.
For a cleaner accompaniment, place the root in the left hand and play the remaining tones in the right. With extended chords, keep the third and seventh because they identify the chord quality most clearly.
How to play Fsus4 on guitar
Try the shape 1-1-3-3-1-1 in standard tuning, read from low E to high E. The sounding-string details are: E fret 1: F; A fret 1: B♭; D fret 3: F; G fret 3: B♭; B fret 1: C; E fret 1: F. Keep every note clear and release pressure from strings marked “x.”
This is one voicing, not the only correct shape. The chord remains Fsus4 whenever the essential pitch classes are present; doubling, omission, and bass-note choice change the voicing rather than the basic chord name.
