The E dominant 7th chord (E7) is built from a root note (E), a major third (G#), a perfect fifth (B) and a minor seventh (D):
- Type: major tetrad.
- Formule: 1 3 5 ♭7.
- Music notes: E (1) G# (3) B (5) D (♭7).
- Chords to play with: IVmaj7 (Amaj7) y V7 (Bm7).
E7 chord [Musical explanation]
The E dominant seventh chord is a tetrad with formula 1 – 3 – 5 – ♭7. Therefore, to build it we need E (1), G# (3), B (5) and D (♭7):
This is due to the fact that a dominant seventh chord is made up of 3 third intervals:
- A major interval (4 half steps between the 3rd and root).
- A minor interval (3 half steps between the 5th and 3rd).
- A minor interval (3 half steps between the 7th and 5th).
If we apply this principle to the E7 chord we obtain that:
- G# is the major third of E because it is 4 half steps above the root.
- B is the perfect fifth of E because it is 3 half steps above the 3rd.
- D is the major seventh of E because it is 3 half steps above the 5th.
Thus, this confirms that a major seventh chord is defined by:
Root (E) – Major Third (G#) – Perfect Fifth (B) – Minor Seventh (D)
To sum up, in order to build the E7 chord we need to add the minor seventh (7th) to the E major chord.
E7 Guitar Chord
The E7 chord guitar has the following shape on the fretboard:
Let’s analyze in detail this chord diagram above to make sure that we understand how to play the E7 on guitar.
Let’s start by analyzing the 2 circles in blue, which indicate that on the strings 5 (A) and 3 (G) we have to place the fingers 2 (middle) and 1 (index).
Note by the way the number 1 in black on the left that indicates on which fret we start playing the chord.
On the other hand, at the top we see that we have the characters:
E B D G# B E
This simply means that in the:
- Sixth string sounds the E note.
- Fifth string sounds the B note.
- Fourth string sounds the D note.
- Third string sounds the G# note.
- Second string sounds the B note.
- First string sounds the E note.
And at the bottom we find the numbers:
1 5 ♭7 3 5 1
This indicates that in the:
- Sixth string sounds the root (1).
- Fifth string sounds the perfect fifth (5).
- Fourth string sounds the minor seveth (♭7).
- Third string sounds the major third (3).
- Second string sounds the perfect fifth (5).
- First string sounds the root (1).
⚠️ Important: it is not mandatory to memorize all this information to play the E7 chord on guitar. But it is highly recommended to know it in order to understand the musical theory behind each chord.
