Suspended Chords (Sus2 and Sus4) Complete Guide
Suspended chords replace the 3rd with the 2nd or 4th degree, creating an open, ambiguous sound that neither sounds major nor minor. Used everywhere from pop anthems to lo-fi beats.
What Is a Suspended Chord?
In a standard major chord (C = C-E-G), the middle note E is the 3rd. It is what makes the chord sound major. In a minor chord (Cm = C-Eb-G), the Eb 3rd is what makes it sound minor.
A suspended chord removes the 3rd entirely and replaces it with either the 2nd or the 4th scale degree:
Sus2 vs Sus4 vs Major vs Minor
| Chord | Formula | Notes (C) | Feel | Resolves to |
|---|---|---|---|---|
| Csus2 | 1-2-5 | C-D-G | Open, bright, floating | C major or Am |
| Csus4 | 1-4-5 | C-F-G | Tense, dramatic, expectant | C major |
| C major | 1-3-5 | C-E-G | Happy, bright, resolved | None (already resolved) |
| C minor | 1-b3-5 | C-Eb-G | Sad, emotional, resolved | None (already resolved) |

How Sus Chords Resolve
Sus2 Resolution
The 2nd can move up to the major 3rd or down to form a relative minor.
Sus4 Resolution
The 4th wants to fall down to the major 3rd. This resolution feels strong and satisfying.

Famous Songs Using Sus Chords
The iconic four-note motif that opens the song is built around a Dsus4-D figure, giving the melody its haunting urgency
Pete Townshend famously plays a sustained Asus4 for the entire verse section before releasing it, creating a massive tension-and-release rock effect
The acoustic intro alternates between Gsus2 and C to create the open, floating intro feel that defines the song's tone
The mandolin-driven intro uses sus2 chord voicings to create the wistful, unsettled atmosphere
The arpeggiated piano pattern that defines the song uses Ebsus2 as its foundation, creating the ticking-clock feeling without resolving to a full Eb major
The piano arpeggiation uses A sus2 voicings throughout to keep the harmonic motion subtle and emotional underneath the vocal melody
6 Production Tips for Sus Chords
Sus2 chords loop without getting boring because they never fully resolve to major or minor. A Csus2 - Gsus2 - Fsus2 loop can run for bars without feeling repetitive.
Place a sus4 chord in the bar before your chorus or drop. The unresolved 4th creates tension that makes the resolution on beat 1 of the next section feel massive.
Use BeatKey to detect the key of a sample, then build sus2 and sus4 chords off that root note using the table above. Sus chords work in both major and minor contexts.
In gospel and soul, replacing the standard V chord with Vsus4 before the final resolution is a classic tension move. In C major: Gsus4 resolving to G before landing on C is a staple.
Sus2 chords work exceptionally well as arpeggio patterns in DAWs. The open 5th (root and 5th) with the floating 2nd creates the Coldplay/ambient piano style. Try C-G-D-G repeating at 90 BPM.
The 7sus4 chord (1-4-5-b7) is a funk and neo-soul staple. E7sus4 = E-A-B-D. It creates that signature floating dominant sound without fully committing to a major chord. Perfect for one-chord vamps.
Frequently Asked Questions
What is a suspended chord?
A suspended chord replaces the 3rd of a chord with either the 2nd (sus2) or 4th (sus4) scale degree. Because there is no 3rd, the chord is neither major nor minor, creating an open, ambiguous quality that wants to resolve.
What is the difference between sus2 and sus4?
Sus2 uses the 2nd degree (1-2-5) and sounds open and bright. Sus4 uses the 4th degree (1-4-5) and sounds tenser, wanting to resolve down to the 3rd. Sus4 is more dramatic and common in rock and gospel; sus2 is more floating and common in pop and ambient.
How do you resolve a sus chord?
Sus4 resolves when the 4th drops to the major 3rd (Csus4 to C major: F drops to E). Sus2 can resolve when the 2nd rises to the major 3rd (Csus2 to C major: D rises to E), or you can leave it unresolved for a floating, ambient effect.
What is a sus7 chord?
The term "sus7" is informal. The standard extended sus chord is the 7sus4 (also written dom7sus4 or just sus), which adds a b7 to the sus4 formula: 1-4-5-b7. It is common in jazz, gospel, and neo-soul. "Csus2/B" or "sus7 voicing" usually refers to a sus2 chord over a bass note a semitone below, creating a rich R&B color.
