The root left to the bass player. Frees a finger for a tension.
Ebmaj11 is Eb, G, Bb, D, F and Ab — Ebmaj9 with the eleventh added — the note that fights the major third.
It sounds unsettled, and grittier than the rest of the major family. Most players drop the third or raise the eleventh instead, which is how you arrive at a sus chord or at maj7♯11.

| Eb | G | Bb | D | F | Ab |
|---|---|---|---|---|---|
| 1 | 3 | 5 | 7 | 9 | 11 |
Tonic, awkwardly — the eleventh sits a semitone above the third.
Also written EbM11, EbΔ11 or Eb major 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.
Ebmaj11 has 26 of them, on the top four strings, the middle four strings and strings 5-3-2-1, from open position up to the 13th — every inversion the chord has: G in the bass, Bb in the bass, D in the bass, F in the bass and Ab in the bass. The one to learn first is the F shape at the nut, which is the easiest grip here.
9 of them sit on the top 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 xx1133 — no barre and down at the nut. None of the shapes for Ebmaj11 uses an open string, so every one of them is movable; the lowest sits at the 1st fret. 3 of the 6 need a barre. Together they cover the neck from the 1st fret to the 13th.
| Frets | Where | Bass | Top | Hand |
|---|---|---|---|---|
| xx1133 | 1st fret | Eb, root position | G | all fretted |
| x65744 | 4th fret | Eb, root position | Ab | all fretted |
| x66786 | 6th fret | Eb, root position | Bb | barred |
| 11-10-x-x-9-10 | 9th fret | Eb, root position | D | all fretted |
| 11-11-12-12-11-11 | 11th fret | Eb, root position | Eb | barred |
| 11-11-12-12-11-13 | 11th fret | Eb, root position | F | barred |
The same notes rebuilt from scratch give 6 shell, 13 drop 2, 9 drop 3 and 3 open string voicings, each on its own page.
Tensions. A shell of Ebmaj11, root, third and seventh, leaves a string free, and the tones that belong over it are the 13 (C).
How you get to it. The turn that lands on Ebmaj11 is Fm7 to Bb7 — the ii and the V of Eb — and Bb7 shares its third and seventh with Fm7, so the hand barely moves between them.
