Dsus4 chord on guitar: fingering and notes

Dsus4 is a suspended fourth (sus4) chord made of D, G and A. This shape uses 4 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

Index finger on string 3 (G), fret 2.
Middle finger on string 2 (B), fret 3.
Ring finger on string 1 (high E), fret 3.
Let string 4 (D) ring open.
Don’t play string 6 (low E) and string 5 (A): start your strum on string 4 (D).

Notes in the chord

Formula: 1 – 4 – 5

String	Fret	Note	Interval
string 4 (D)	open	D	root
string 3 (G)	2	A	perfect fifth
string 2 (B)	3	D	root
string 1 (high E)	3	G	perfect fourth

Check that every string rings

Pick the strings one at a time from string 4 (D) 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.
Strings you don’t play should stay silent: aim the strum, or touch them lightly with a free finger.

Practise: change between Dsus4 and D

Set the metronome to 60 BPM in 4/4 (the button below applies these settings).
Strum Dsus4 once on beat 1 and let it ring through beats 2, 3 and 4.
During beat 4, lift your fingers and move to D so it sounds exactly on the next beat 1.
Keep alternating Dsus4 and D 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

Where this chord is used

Suspended chords usually stand in for, or lead into, the plain chord on the same root: try Dsus4 → D.
