About Eb9#11 — shell voicings
Eb9#11 is Eb, G, Bb, Db, F and A — Eb9 with the raised eleventh added on top.
It sounds wide and glassy, bright rather than tense. The ♯11 clears the major third by a whole step, so it adds height without the collision a natural eleventh makes.

How to play Eb9#11
Root, third and seventh. The third and seventh, the guide tones, are what make the chord major, minor or dominant, so the fifth can go: it says nothing the symbol needs.
Three notes means a spare string, which is the real point. Put a tension on it.
Eb9#11 has 11 of them, on the top four strings, the middle four strings, the bottom four strings, strings 5-3-2-1 and strings 6-4-3-2, from open position up to the 12th — all in one inversion, so the bass note never moves. The one to learn first is the Eb shape at the nut, which is the easiest grip here.
3 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 xx1223 — no barre and down at the nut. None of the shapes for Eb9#11 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 12th.

|---|---|---|---|---|
| xx1223 | 1st fret | Eb, root position | G | all fretted |
| x65665 | 5th fret | Eb, root position | A | barred |
