The root left to the bass player. Frees a finger for a tension.
Eb11 is Eb, Bb, Db, F and Ab — Eb9 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.

| Eb | Bb | Db | F | Ab |
|---|---|---|---|---|
| 1 | 5 | ♭7 | 9 | 11 |
Dominant — but effectively a sus chord with a ninth.
Also written Eb9sus4 or Eb dominant 11. The same chord either way; which spelling you meet depends on who wrote the chart.
Leave the root to the bass player. In a band nobody misses it, and the ear supplies it from the guide tones anyway.
The finger it frees goes to a tension, which is why these sound richer than the shape they came from rather than thinner.
Eb11 has 14 of them, on the middle four strings, the top four strings and strings 5-3-2-1, from open position up to the 13th — every inversion the chord has: Bb in the bass, Db in the bass, F in the bass and Ab in the bass. The one to learn first is the Bb shape at the nut, which is the easiest grip here.
5 of them sit on the middle four strings, 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 x65644 — no barre and low, at the 4th fret. None of the shapes for Eb11 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 |
|---|---|---|---|---|
| 111123 | 1st fret | F, 9th in the bass | G | barred |
| x65644 | 4th fret | Eb, root position | Ab | all fretted |
| x66686 | 6th fret | Eb, root position | Bb | barred |
| x-10-8-8-9-9 | 8th fret | G | Db | all fretted |
| 11-11-11-12-11-11 | 11th fret | Eb, root position | Eb | barred |
The same notes rebuilt from scratch give 25 drop 2 and 17 drop 3 voicings, each on its own page.
Eb11 is the V of Ab, and that is where it goes if it goes anywhere: the third and the flat seventh are a tritone apart, and both resolve by a semitone into Ab.
Voice by voice, Eb11 → Ab. One voice moves by a semitone, and 2 notes are common to both chords.
| In Eb11 | Moves | In Ab |
|---|---|---|
| Eb, the root | stays where it is | Eb, the fifth |
| Bb, the fifth | falls a whole tone | Ab, the root |
| Db, the flat seventh | falls a semitone | C, the major third |
| F, the ninth | falls a whole tone | Eb, the fifth |
| Ab, the eleventh | stays where it is | Ab, the root |
