E7: guitar chord voicings, inversions, scales and arpeggios

E7 (Dominant 7) is an interactive GuitarArcanum page with chord formula, intervals, voicings, inversions, triads, pentatonic patterns, scales and arpeggios on the fretboard.

Chord formula

Interval formula: 1 3 5 b7. A major triad with a minor 7th. A tense chord that wants to resolve — the engine of tonal music and the backbone of the blues.

Chord tones

Between the major 3rd and the b7 sits a tritone — the source of the tension and the pull. That tritone is what makes it a dominant.

Sound character

Tense but energetic. In the blues it's self-sufficient; in tonal music it pulls to the tonic.

Harmonic function

A dominant (the V). It pulls up a fourth to the tonic. In the blues it sits on every degree.

Typical progressions

F#m7 – B7 – Emaj7
E7 – A7 – B7 (blues)
B7 → C
