Key Signature

A Suspended 2nd chord is built from symmetrical or ambiguous intervals, so it doesn't belong to a single key and has no key signature of its own.

F Suspended 2nd : Frequently Asked Questions

What is the F Suspended 2nd chord on piano?
The F Suspended 2nd chord contains the notes F – G – C. On piano, play these notes together to sound the chord.
What notes are in the F Suspended 2nd chord?
The F Suspended 2nd chord (Fsus2) contains: F (root), G (major 2nd), and C (perfect fifth). The major 2nd replaces the third entirely, there is no major or minor third, giving this chord its open, floating quality.
How does F Suspended 2nd differ from F Major or F Minor?
Both F Major and F Minor have a third (E or Eb for C-based chords). F Suspended 2nd replaces that third with a major 2nd (G). This suspension creates ambiguity: the chord is neither major nor minor and has a bright, airy sound often used for colour and transition.
What does "suspended" mean in music?
"Suspended" means the third has been replaced (suspended) by another note: in this case, the 2nd degree. The suspension creates tension that traditionally resolves back to the third (moving from G to the major or minor third). In pop music, suspended chords often remain unresolved for their pleasant, neutral sound.
How is F Suspended 2nd used in music?
Sus2 chords are widely used in pop, rock, and folk as colour chords that avoid defining major or minor quality. Fsus2 works before or after a F Major chord in the same harmonic context, creating a shimmer effect. It also appears at phrase endings for an open, unresolved feeling.
What songs use suspended 2nd chords?
Suspended chords are everywhere in pop: Every Breath You Take (Police) uses sus chords throughout. Pinball Wizard (The Who) opens with sus4 chords. Somebody That I Used to Know (Gotye) uses sus2 for its characteristically open sound. The floating quality of sus2 chords suits introspective and atmospheric music.
Can I use F Suspended 2nd and F Major together?
Yes: alternating between Fsus2 and F Major is a very common pop technique. The movement F–G–C → F–(major 3rd)–C creates a shimmer with only one note changing. This single-note movement is the basis of many recognisable piano and guitar parts.

Where these facts come from

Every value on this page is derived from the note formula for a suspended 2nd applied to the root F, using standard music theory. Nothing here is hand-entered per chord, so the notes, intervals, inversions and frequencies cannot drift out of agreement with each other. Pitches assume 12-TET at A440.
