Root, third and seventh: the guide tones fix the quality, so the fifth is dropped. That is what leaves a string free, so pick a tension to put on top.
E9#11 is E, G#, B, D, F# and A# — E9 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.

| E | G# | B | D | F# | A# |
|---|---|---|---|---|---|
| 1 | 3 | 5 | ♭7 | 9 | ♯11 |
Dominant — the lydian dominant sound.
Also written E9(#11), E9+11 or E9♯11. The same chord either way; which spelling you meet depends on who wrote the chart.
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.
E9#11 has 10 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 13th — all in one inversion, so the bass note never moves. The one to learn first is the E 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 010100 — no barre and 4 open strings. 2 of the 8 shapes here sit in open position. 3 of the 8 need a barre. Together they cover the neck from the 1st fret to the 13th.

Tensions. A shell of E9#11, root, third and seventh, leaves a string free, and the tones that belong over it are the b13 (C) and the 13 (C#).
E9#11 is a dominant with its tension raised, so it still points at A — harder than a plain seventh does, because the altered tones sit a semitone from where they are going.
Voice by voice, E9#11 → A. 3 voices move by a semitone, and one note is common to both chords.
| In E9#11 | Moves | In A |
|---|---|---|
| E, the root | stays where it is | E, the fifth |
| G#, the major third | rises a semitone | A, the root |
| B, the fifth | falls a whole tone | A, the root |
| D, the flat seventh | falls a semitone | C#, the major third |
| F#, the ninth | falls a whole tone | E, the fifth |
| A#, the sharp eleventh | falls a semitone | A, the root |
Every note of E9#11 is in E lydian dominant.
Change one note of E9#11 and you have E9 (drop the flat fifth), E9b5 (drop the fifth) or E13 (the flat fifth becomes a sixth).
E9#11 is an altered chord — a dominant seventh with its fifth or ninth moved. Altered dominant chords on every root.
