What E7 is built from
Counting up in semitones from E:
| Note | Interval | Semitones from root |
|---|---|---|
| E | root | 0 |
| G♯ | major third | 4 |
| B | perfect fifth | 7 |
| D | minor seventh | 10 |
Move all four of those the same distance and you get the same chord on another root — that is what the dominant seventh formula 0 – 4 – 7 – 10 means.
How to play E7
All six strings are played. The low E, D, B and top E strings ring open. Nothing is higher than fret 2, so it sits in first position.
All four strings are played. The E string rings open. Nothing is higher than fret 2, so it sits in first position.
Play E, G♯, B and D together. That is three white keys and one black.
Numbers in the grids are frets. Where a number is printed beside a grid, that is the fret the top row stands for; otherwise the thick bar at the top is the nut. A circle above a string means play it open, a cross means leave it out.

E7 on the stave
The same four notes written on a treble stave, spelled the way a dominant seventh is spelled — one letter for every other step, with whichever accidental reaches the pitch. That is why it reads E, G♯, B and D, and not the same sounds written some other way.
Which keys E7 belongs to
| Key | Relative minor | Degree |
|---|---|---|
| A major | F♯ minor | V7 |
Each row is a key whose scale contains every note of E7. A major key and its relative minor use the same seven notes, so the chord belongs to both.
Chords that sit next to E7
The seven triads built on the scale of A major. These are the chords E7 is most often played alongside, because they are made from the same seven notes. The small numeral is the degree each one stands on.
