- 2nd inversion (F/C)C – F – A
Key Signature
A chord has no key signature of its own, but the F Major is the tonic (I) chord of F Major, whose key signature has 1 flat (B♭).
Order of flats
Flats are added in a fixed order — the reverse of the sharp order. Each new flat key adds the next flat on the list.

- In F major, F Major is the I chord — the tonic.
- In A minor, F Major is the VI chord — the tonic.
- In B♭ major, F Major is the V chord — the dominant.
- In C major, F Major is the IV chord — a predominant.
- In D minor, F Major is the III chord — a mediant / color chord.
- In G minor, F Major is the ♭VII chord — a mediant / color chord.

Spans are measured centre to centre at a 165 mm octave (standard keyboard geometry).
| Position | Bass note | Notes in order | Figured bass | Semitones | Span |
|---|---|---|---|---|---|
| Root position | F | F3, A3, C4 | 5/3 | 7 | 96 mm |
| First inversion: F/A | A | A3, C4, F4 | 6/3 | 8 | 110 mm |
| Second inversion: F/C | C | C4, F4, A4 | 6/4 | 9 | 124 mm |
One position per chord tone in the bass. Spans are for close position: voiced inversions appear under Voicings.

Where these facts come from
Every value on this page is derived from the note formula for a major 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.
