E13 chord (E dominant thirteenth)
The E13 chord contains 7 written tones: E, G♯, B, D, F♯, A, C♯. Its interval formula is 1–3–5–♭7–9–11–13.
E13 chord notes and interval formula
The formula 1–3–5–♭7–9–11–13 means the chord is measured from E using the root, major third, perfect fifth, minor seventh, major ninth, perfect eleventh, and major thirteenth. In semitone numbers from the root, the pattern is 0–4–7–10–14–17–21. On a real instrument, it is normal to omit a less important tone—usually the fifth—when the full closed position is too dense.
| Degree | Interval | Semitones | Note |
|---|---|---|---|
| 1 | Root | 0 | E |
| 3 | Major Third | 4 | G♯ |
| 5 | Perfect Fifth | 7 | B |
| ♭7 | Minor Seventh | 10 | D |
| 9 | Major Ninth | 14 | F♯ |
| 11 | Perfect Eleventh | 17 | A |
| 13 | Major Thirteenth | 21 | C♯ |
How to play E13 on piano
Start with the notes in root position from low to high: E – G♯ – B – D – F♯ – A – C♯. Split the chord between both hands and omit the fifth when necessary is a useful starting point, but black-key combinations and melodic movement may make another fingering more comfortable.
For a cleaner accompaniment, place the root in the left hand and play the remaining tones in the right. With extended chords, keep the third and seventh because they identify the chord quality most clearly.
How to play E13 on guitar
Try the shape 0-0-0-1-2-2 in standard tuning, read from low E to high E. The sounding-string details are: E open: E; A open: A; D open: D; G fret 1: G♯; B fret 2: C♯; E fret 2: F♯. Keep every note clear and release pressure from strings marked “x.”
This is one voicing, not the only correct shape. The chord remains E13 whenever the essential pitch classes are present; doubling, omission, and bass-note choice change the voicing rather than the basic chord name.
E13 inversions and slash chords
Inversions keep the same notes but place a different chord tone in the bass. They are useful for smoother bass lines, compact keyboard movement, and alternative guitar voicings.
| Position | Symbol | Notes low to high | Bass |
|---|---|---|---|
| Root position | E13 | E – G♯ – B – D – F♯ – A – C♯ | E |
| 1st inversion | E13/G# | G♯ – B – D – F♯ – A – C♯ – E | G♯ |
| 2nd inversion | E13/B | B – D – F♯ – A – C♯ – E – G♯ | B |
| 3rd inversion | E13/D | D – F♯ – A – C♯ – E – G♯ – B | D |

The E dominant thirteenth chord is dense, colorful, and directional. A complete thirteenth chord contains more notes than most hands or guitar shapes can comfortably play. In practice, players keep the third, flat seventh, and thirteenth, then add the root and ninth as space allows.
