About F11 — drop 3 voicings
F11 is F, C, Eb, G and Bb — F9 with the eleventh added, and the third usually dropped.
It sounds suspended rather than tense. The eleventh sits a semitone above the major third, so the third is usually dropped; some shapes here keep it anyway.
F11 notes and formula
| F | C | Eb | G | Bb |
|---|---|---|---|---|
| 1 | 5 | ♭7 | 9 | 11 |
Dominant — but effectively a sus chord with a ninth.
Also written F9sus4 or F dominant 11. The same chord either way; which spelling you meet depends on who wrote the chart.
How to play F11
The same operation one voice further down: the third voice from the top falls an octave and becomes the bass.
That leaves a bigger hole under the top three notes, so a string gets skipped: the muted string in the middle is the shape, not a mistake.
F11 has 16 of them, on strings 5-3-2-1 and strings 6-4-3-2, from open position up to the 11th — every inversion the chord has: F in the bass, C in the bass, Eb in the bass, G in the bass and Bb in the bass. The one to learn first is the Bb shape at the nut.
8 of them sit on strings 5-3-2-1, so you can run the inversions up one set without changing strings — which is the whole reason to learn them as a family rather than as separate grips.
Start with x87866 — no barre. None of the shapes for F11 uses an open string, so every one of them is movable; the lowest sits at the 1st fret. 3 of the 5 need a barre. Together they cover the neck from the 1st fret to the 12th.
| Frets | Where | Bass | Top | Hand |
|---|---|---|---|---|
| 111211 | 1st fret | F, root position | F | barred |
| 333345 | 3rd fret | G, 9th in the bass | A | barred |
| x87866 | 6th fret | F, root position | Bb | all fretted |
| x-8-8-8-10-8 | 8th fret | F, root position | C | barred |
| x-12-10-10-11-11 | 10th fret | A | Eb | all fretted |
