Sus Chords on Guitar: Sus2 and Sus4 Explained (With Easy Shapes)

If you've ever wondered how acoustic players make a simple D chord sound so alive, the answer is usually a suspended chord. By lifting or adding one finger, they flick between D, Dsus4 and Dsus2, creating a moving, shimmering pattern that sounds far more complex than it is.

Suspended chords, or "sus" chords, are some of the easiest and most rewarding chords on the guitar. This guide explains what they are, gives you the most useful shapes, and shows you how to use them in songs.

What is a suspended chord?

A normal major or minor chord has three notes: the root, the third and the fifth. The third is the note that decides whether the chord sounds happy (major) or sad (minor).

A suspended chord removes the third and replaces it with a different note:

• Sus2 replaces the third with the second note of the scale. It sounds open, airy and unfinished in a pleasant way.
• Sus4 replaces the third with the fourth note of the scale. It sounds tense, like it's leaning forward and wants to fall back to the major chord.

Because the third is gone, sus chords are neither major nor minor. That ambiguity is exactly what makes them sound so interesting, and why they fit into so many different songs.

The most useful sus chord shapes

Dsus2, D and Dsus4

This trio is the most famous sus chord move on the guitar. All three use the same index and ring fingers on the G and B strings. Only the high E string changes:

• Dsus2: leave the high E string open.
• D: middle finger on the second fret of the high E.
• Dsus4: pinky on the third fret of the high E.

Strum D, then add your pinky for Dsus4, then take it off; lift your middle finger for Dsus2, then put it back. That little dance is the sound of a thousand acoustic songs.

Asus2, A and Asus4

The same idea, on the B string. A major has three fingers on the second fret of the D, G and B strings.

• Asus2: lift the finger off the B string so it rings open.
• Asus4: move the B-string finger up to the third fret.

Playing A with your index and middle fingers on the D and G strings, and your ring finger on the B string, makes both changes easy.

Esus4 and E

Esus4 frets the A, D and G strings at the second fret, with the low E, B and high E strings open. Switch between Esus4 and E by moving one finger: on E, the G string is fretted at the first fret instead of the second. Esus4 to E is a classic rock move.

Csus2 and Csus4

Csus2 is played x30013: ring finger on the third fret of the A string, index on the first fret of the B string and pinky on the third fret of the high E, with the D and G strings open. Csus4 is x33011: the A and D strings at the third fret, the G string open, and the B and high E strings at the first fret, usually with a small index-finger barre. These are less common than the D, A and E versions, and many players use the similar-sounding Cadd9 instead, but they are worth knowing.

How to use sus chords in songs

1. Decorate a chord you're holding

When a song stays on one chord for a whole bar or more, add movement by switching to its sus2 or sus4 and back. On D, try: D for two beats, Dsus4 for one beat, D for one beat. This keeps the rhythm interesting without changing the harmony.

2. Build tension before a resolution

Sus4 chords naturally want to fall back to the major chord. Play Asus4 for a beat or two before resolving to A, and the arrival feels satisfying. This is especially effective at the end of a verse or a song.

3. Replace a plain chord for color

Swap a plain chord for its sus2 version for a more modern, open sound. Dsus2 instead of D or Asus2 instead of A can make a simple progression sound fresh.

4. Use them in minor songs too

Because sus chords aren't major or minor, Asus2 can work in a song in A minor where A major would sound wrong. That flexibility is useful when you're writing your own music.

Sus chord patterns to practice

Sus chords vs. add chords

Sus chords are often confused with add chords like Cadd9. The difference is simple:

• A sus chord replaces the third. Dsus2 has no F♯.
• An add chord keeps the third and adds a note. Cadd9 still has the E that makes it major, plus an added D.

Both sound open and modern, and they often appear together. Cadd9 is a very popular substitute for C in acoustic music because it fits easily between G and D.

Sus chords in different styles

• Acoustic pop and folk: D, A and E sus decorations are everywhere, usually with a light, flowing strum.
• Rock: Esus4 to E and Asus4 to A create punchy riffs, especially with distortion.
• Worship and contemporary music: sus2 and add9 chords give the wide, open sound common in modern worship songs.
• Jazz and soul: sus4 chords often appear before a dominant seventh, as in D7sus4 to D7, to build tension.

Writing your own sus chord riffs

Sus chords are a great starting point for writing your own music. Because you only move one finger, it's easy to create little melodies on top of a chord. Try this exercise:

1. Hold a D chord and strum a steady rhythm, four beats to a bar.
2. On beat three of every bar, add your pinky for Dsus4.
3. On beat four, lift your middle finger for Dsus2.
4. Return to D on the next beat one.

Now try the same idea on A, then move between the two chords: one bar of decorated D, one bar of decorated A. You've written the kind of acoustic part that appears in a huge number of songs.

Next, experiment with the order and timing. Put the sus4 on the "and" of beat two instead of beat three, or hold the sus2 for a full bar before returning to the major chord. Small changes in timing create completely different feels, and they're a great way to make a familiar progression sound like your own.

Strumming tips for sus chords

• Change on the upstroke. Adding or lifting a finger between a downstroke and an upstroke makes the movement sound smooth and natural.
• Let the open strings ring. Much of the charm of sus2 chords comes from open strings. Keep your fingers arched so nothing gets muted.
• Use a lighter touch. Sus decorations sound best when they shimmer rather than crash. Strum a little softer and closer to the soundhole.

Common mistakes

• Strumming the wrong strings. Dsus2 and Dsus4 should be strummed from the D string, just like D.
• Lifting more than one finger. In the D sus moves, only one finger changes. Keep the others planted.
• Overusing sus4. Sus4 creates tension. If you never resolve it, the song can feel unsettled.

A little theory, if you want it

In the key of D, the scale is D, E, F♯, G, A, B, C♯. A D chord uses D, F♯ and A. Dsus2 replaces F♯ with E (the second note). Dsus4 replaces F♯ with G (the fourth note). The same logic works for every chord, which means you can work out any sus chord once you know the scale. Our guide to the major scale on guitar explains scales in more detail.

Sus chords with a capo

Because the D, A and E sus shapes rely on open strings, they sound especially good with a capo. Put a capo on the 2nd fret and play the D, Dsus4, Dsus2 pattern: you're now in the key of E, with a brighter, chiming tone. Move the capo to the 5th fret for a sparkling high voicing that layers beautifully over a second guitar playing open chords. It's an easy way to make the same few shapes cover many different songs and keys.
