Fsus4 Suspendido 4ª Acorde

The F Suspendido 4ª chord contains: F, A#, C.

These notes are derived by applying the suspended 4th interval formula (0–5–7 semitones) to the root note F.

Replaces the third with a perfect fourth.

Classic rock tension before resolution. The Fsus4 chord is used across pop, rock, jazz, and classical music. As the I chord in the key of F major, it functions as the most stable resting point in progressions.

On piano, play F, A#, C simultaneously.

In root position, F is the lowest note. Inversions move the bass note up — first inversion has A# lowest, second inversion has C lowest.

A suspended 4th chord has 3 notes: F, A#, C (in F).

It is a triad — the most fundamental chord type.

The F major chord (F–A–C) uses a major third (4 semitones), giving it a bright, happy sound.

The F minor chord (F–G#–C) uses a minor third (3 semitones), giving it a darker, emotional sound.

Fsus4 naturally serves as the I chord in the key of F major.

It also appears as IV in the key of C major, and as V in the key of A# major.

Yes.

The ukulele uses GCEA tuning with 4 strings. The Fsus4 chord notes (F, A#, C) can be fretted on a ukulele, though the shapes differ from guitar due to the 4-string layout and shorter scale.

In the key of F major, Fsus4 pairs naturally with A# major (IV), C major (V), and Dm (vi).

The classic I–IV–V (Fsus4–A#–C) is the foundation of blues, country, and rock.

An inversion places a non-root note in the bass.

Fsus4 root position: F in bass. First inversion: A# in bass. Second inversion: C in bass. Inversions create smoother bass line movement without changing the harmony.

Remember the formula: 0–5–7 semitones from root.

For Fsus4: start on F, add 5 semitones, then 7 semitones. Practicing this across all 12 roots builds instant recognition of any suspended 4th chord.
