E7 chord on guitar: fingering and notes

E7 is a dominant seventh chord made of E, G♯, B and D. This shape uses 6 strings in open position.

Read the diagram as if the guitar stands in front of you: thickest string on the left, the nut at the top. Numbers are fingers (1 index … 4 little), ○ means play the string open, × means don’t play it.

Where each finger goes

Middle finger on string 5 (A), fret 2.
Index finger on string 3 (G), fret 1.
Let string 6 (low E), string 4 (D), string 2 (B) and string 1 (high E) ring open.

Notes in the chord

Formula: 1 – 3 – 5 – ♭7

String	Fret	Note	Interval
string 6 (low E)	open	E	root
string 5 (A)	2	B	perfect fifth
string 4 (D)	open	D	minor seventh
string 3 (G)	1	G♯	major third
string 2 (B)	open	B	perfect fifth
string 1 (high E)	open	E	root

Check that every string rings

Pick the strings one at a time from string 6 (low E) to string 1. Every note should ring for about a second without buzzing or going dull.
A dull or muted note usually means a fingertip is leaning on the next string: arch the finger so only the tip touches.
A buzzing note usually means the finger is too far from the fret wire: slide it closer without pressing harder.

Practise: change between E7 and Am

Set the metronome to 60 BPM in 4/4 (the button below applies these settings).
Strum E7 once on beat 1 and let it ring through beats 2, 3 and 4.
During beat 4, lift your fingers and move to Am so it sounds exactly on the next beat 1.
Keep alternating E7 and Am for eight bars. When three changes in a row land on the beat with every string ringing, raise the tempo by 5 BPM.

What to listen for: the new chord starts on the click of beat 1, not after it, and no string goes silent during the change.

Practise at 60 BPM
