About Eaug7 — drop 3 voicings
Eaug7 is E, G#, B# and D — E7 with the fifth raised a semitone.
It sounds strained and chromatic. The raised fifth is heard as a ♭13 sitting a semitone above where it is going, so the chord pushes harder than a plain dominant.
Eaug7 notes and formula
| E | G# | B# | D |
|---|---|---|---|
| 1 | 3 | ♯5 | ♭7 |
Altered dominant — the pull of a 7, sharpened.
Also written E7#5, E+7 or E7(#5). The same chord either way; which spelling you meet depends on who wrote the chart.
How to play Eaug7
The same operation one voice further down: the third voice from the top falls an octave and becomes the bass.
That leaves a bigger hole under the top three notes, so a string gets skipped: the muted string in the middle is the shape, not a mistake.
Eaug7 has 10 of them, on strings 5-3-2-1 and strings 6-4-3-2, from open position up to the 12th — every inversion the chord has: E 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.
5 of them sit on strings 5-3-2-1, 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 030110 — 3 open strings and only 3 fretted notes. 1 of the 6 shapes here sits in open position. None of them needs a barre. Together they cover the neck from the 1st fret to the 13th.
| Frets | Where | Bass | Top | Hand |
|---|---|---|---|---|
| 030110 | open position | E, root position | E | 3 open strings |
| xx2534 | 2nd fret | E, root position | G# | all fretted |
| x767x8 | 6th fret | E, root position | B# | all fretted |
| x-7-10-7-9-8 | 7th fret | E, root position | B# | all fretted |
| 12-11-12-x-13-x | 11th fret | E, root position | B# | all fretted |
| 12-x-12-13-13-x | 12th fret | E, root position | B# | all fretted |
The same notes rebuilt from scratch give 4 shell, 15 drop 2 and 1 open string voicings, each on its own page.

How to use Eaug7
Eaug7 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, Eaug7 → A. 3 voices move by a semitone, and one note is common to both chords.
| In Eaug7 | 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 sharp fifth | rises a semitone | C#, the major third |
| D, the flat seventh | falls a semitone | C#, the major third |
