E7 is a type of dominant seventh chord– keep in mind, a significant triad plus a flatted seventh. An E major triad is spelled E G # B, as displayed in Example 1, and an E7 chord includes the notes E, G #, B, and D (Example 2).
If you play a standard open E chord, you can make an E7 simply by eliminating your 3rd finger, as illustrated in Example 3a. You might also get an E7 by taking the open E shape and including your fourth finger on the third-fret D on string 2 (Example 3b).
Example 4 shows how to make a closed E7 voicing on the inner four strings, and Example 5 demonstrates how to form E7 from an E barre chord in seventh position. Keep in mind that you might consist of the open low E string for a thicker noise. See Example 6 for some less typical voicings greater up the neck with the third (G #) as the most affordable note.
You must now understand a variety of ways to play E7 across the fretboard. The Beatles’ “Eight Days a Week” is a terrific example of a tune that makes use of the E7 chord. In the next lesson, we’ll continue checking out dominant seventh chords, focusing on B7.
