The standard grips this chord is usually shown with.
E7 is E, G#, B and D — E with the flat seventh added on top.
It sounds restless and pointed at something. The third and the flat seventh are a tritone apart and each moves by a semitone into the next chord; that is the engine of a cadence, and the whole vocabulary of the blues.

| E | G# | B | D |
|---|---|---|---|
| 1 | 3 | 5 | ♭7 |
Dominant — it points a fifth down.
Also written Edom7 or E dominant 7. The same chord either way; which spelling you meet depends on who wrote the chart.
E7 in root position puts E in the bass, which is the chord as it is spelled: the note it is named after underneath everything else.
6 of E7’s 7 common shapes do this: 020100, xx2434, x7675x, x79797, 12-11-9-9-9-10, 12-14-12-13-12-12.
Start with 020100 — no barre and 4 open strings. 1 of the 7 shapes here sits in open position. 4 of the 7 need a barre. Together they cover the neck from the 1st fret to the 14th.
| Frets | Where | Bass | Top | Hand |

The same notes rebuilt from scratch give 6 shell, 15 drop 2, 10 drop 3 and 6 open string voicings, each on its own page.
Tensions. A shell of E7, root, third and seventh, leaves a string free, and the tones that belong over it are the b9 (F), the 9 (F#), the #9 (F##), the #11 (A#), the b13 (C) and the 13 (C#).
E7 is the V of A, and that is where it goes if it goes anywhere: the third and the flat seventh are a tritone apart, and both resolve by a semitone into A.
Voice by voice, E7 → A. 2 voices move by a semitone, and one note is common to both chords.
| In E7 | 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 |
