The standard grips this chord is usually shown with.
Ebaug is Eb, G and B — Eb with the fifth raised a semitone.
It sounds stretched, and suspended between keys. Its commonest job is passing between a major triad and its sixth or seventh, with the raised fifth as a single voice walking up.

| Eb | G | B |
|---|---|---|
| 1 | 3 | ♯5 |
Passing chord — it belongs to no key in particular.
Also written Eb+, Eb(#5) or Eb augmented. The same chord either way; which spelling you meet depends on who wrote the chart.
Ebaug in root position puts Eb in the bass, which is the chord as it is spelled: the note it is named after underneath everything else.
7 of Ebaug’s 8 common shapes do this: x6544x, x6x887, x6988x, xxx887, 11-10-9-8-8-x, 11-x-13-12-12-11, x-x-13-12-12-11.
