The standard grips this chord is usually shown with.
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.
Eb11 in 9th in bass puts F in the bass instead of Eb, the 9th 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 Eb11’s 5 common shapes does this: 111123.
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 |

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.

| 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 |
