F is F, A and C.
It sounds plain and completely at rest. The reference every other chord on this page is a modification of.

| F | A | C |
|---|---|---|
| 1 | 3 | 5 |
Tonic — the chord a progression stops on.
Also written Fmaj, FM or F major. The same chord either way; which spelling you meet depends on who wrote the chart.
F in 2nd inversion puts C in the bass instead of F, the 5th of the chord. The notes are the same; what changes is what the bass line does, which is most of why you would reach for it — it lets the lowest voice move by step where the root would have jumped.
One of F’s 7 common shapes does this: x-x-10-10-10-13.
Start with xx3565 — no barre and low, at the 3rd fret. None of the shapes for F uses an open string, so every one of them is movable; the lowest sits at the 1st fret. 5 of the 7 need a barre. Together they cover the neck from the 1st fret to the 15th.
| Frets | Where | Bass | Top | Hand |
|---|---|---|---|---|
| 133211 | 1st fret | F, root position | F | barred |
| xx3565 | 3rd fret | F, root position | A | all fretted |
| x87565 | 5th fret | F, root position | A | all fretted |
| x-8-10-10-10-8 | 8th fret | F, root position | C | barred |
| 13-12-10-10-10-13 | 10th fret | F, root position | F | barred |
| x-x-10-10-10-13 | 10th fret | C, 2nd inversion | F | barred |
| 13-15-15-14-13-13 | 13th fret | F, root position | F | barred |
The same notes rebuilt from scratch give 47 triad voicings, each on its own page.
How you get to it. The turn that lands on F is Gm7 to C7 — the ii and the V of F — and C7 shares its third and seventh with Gm7, so the hand barely moves between them.
In which keys. Every note of F belongs to C major (the IV), D minor (the ♭III), F major (the I), G minor (the ♭VII), A minor (the ♭VI) and Bb major (the V).
Every note of F is in F major pentatonic, F major, F lydian, F mixolydian and F lydian dominant.
Change one note of F and you have Fm (the major third becomes a minor third), Fsus2 (the major third becomes a ninth), Fsus4 (the major third becomes a fourth), Fmaj7 (add the major seventh), Fadd9 (add the ninth) or F5 (drop the major third).
F is a major chord — root, major third, fifth. Major chords on every root.
On F’s sound and use this page follows Edward Aldwell & Carl Schachter, Harmony and Voice Leading (Schirmer / Cengage, 4th ed., 2011). The shapes and the derived voicings come from different places, and both are explained in where the chords and the theory come from.
Shows each chord the way this style would voice it, and marks which of its alternatives belong to the idiom.
