A close-position chord with the second voice from the top lowered an octave. Sits on four adjacent strings.
Ebmaj7#5 is Eb, G, B and D — Ebmaj7 with the fifth raised a semitone.
It sounds weightless, with no pull in it. Unlike an aug7 there is no flat seventh dragging it anywhere, so it colours a tonic rather than replacing it with a dominant.

| Eb | G | B | D |
|---|---|---|---|
| 1 | 3 | ♯5 | 7 |
Tonic — the lydian augmented sound.
Also written EbM7#5, EbΔ7#5, Eb+M7 or Ebmaj7(#5). The same chord either way; which spelling you meet depends on who wrote the chart.
Take the four notes stacked as close together as they go, then drop the second voice from the top an octave. The gap it opens is what makes the chord sound like a chord rather than a cluster.
It lands on four adjacent strings, which is why it is the workhorse voicing on guitar.
Ebmaj7#5 has 13 of them, on the middle four strings, the bottom four strings and the top four strings, from open position up to the 12th — every inversion the chord has: Eb in the bass, G in the bass, B in the bass and D in the bass. The one to learn first is the B shape at the nut, which is the easiest grip here.
5 of them sit on the middle 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 xx1433 — no barre and down at the nut. None of the shapes for Ebmaj7#5 uses an open string, so every one of them is movable; the lowest sits at the 1st fret. 1 of the 7 needs a barre. Together they cover the neck from the 1st fret to the 13th.

How you get to it. The turn that lands on Ebmaj7#5 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.
Change one note of Ebmaj7#5 and you have Ebmaj7 (the sharp fifth becomes a fifth), Ebmaj7b5 (the sharp fifth becomes a flat fifth), Ebaug (drop the major seventh) or Ebaug7 (the major seventh becomes a flat seventh).
Ebmaj7#5 is a major chord — root, major third, fifth. Major chords on every root.
