An open string left ringing against a fretted grip. Because it costs no finger, it sounds a note the closed shape has none left for -- a tension on top, or a pedal root underneath. Either a familiar grip with open strings added, or a shape so sparse the open strings carry the chord. These belong to their key rather than to a shape, so D, A, G and E have many and Eb a handful.
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.
An open string left ringing against a fretted grip. It costs no finger, so it can sound a note the closed shape has none left for: a tension on top, or a pedal root underneath.
These belong to their key rather than to a shape: they cannot be moved up the neck. D, A, G and E have many; E♭ has a handful.
E9#11 has 1 of them, only on strings 6-4-3-2-1, all of them at the 3rd fret — all in one inversion, so the bass note never moves. The one to learn first is the E shape at the 3rd fret.
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.

The same notes rebuilt from scratch give 10 shell and 13 rootless voicings, each on its own page.
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.
