How to Use Suspended Chords Creatively on Piano
Suspended chords replace the third of a chord with the second (sus2) or fourth (sus4), and on piano you can use them to add tension inside a progression, over a moving bass line, or as melodic fills between a chord and its resolution.
Key points
- A sus4 chord uses the root, perfect fourth and fifth (Csus4 = C F G); a sus2 chord uses the root, second and fifth (Csus2 = C D G).
- You can add a major or dominant seventh to a sus4 chord, and a ninth on top (C F G Bb D).
- Suspended chords create anticipation, which keeps long-held chords in a progression such as I–V–vi–IV from sounding static.
- Holding one sus chord while the bass line moves adds depth, even over a two-chord progression.
- Short sus-to-major fills can support the melody, as long as you use them tastefully.
In this lesson Jason Zac of Nathaniel School of Music explains the main types of suspended chords and shows three practical ways to use them in your piano playing. It suits pianists who already know basic major and minor chords and want their progressions to sound less plain.
The types of suspended chords
All examples are built on C. A suspended chord drops the third and replaces it with a neighbouring note, which leaves the chord sounding unresolved.
- Csus4 = C F G: the root, the perfect fourth and the perfect fifth (1, 4, 5). This is the most popular suspended chord.
- Csus2 = C D G: the root, the second and the fifth (1, 2, 5).
- Sus2 and sus4 together: play C, D and F at once (root, second and perfect fourth). It has no standard name, but it sounds great.
- Sus4 with a seventh: over Csus4 you can add a major seventh (B) or a minor seventh (Bb). The minor seventh is the dominant seventh, giving C7sus4 = C F G Bb. Both colours sit well on top of the sus4.
- Sus4 with a ninth: root, perfect fourth, perfect fifth, dominant seventh and ninth, so C F G Bb D. The ninth is simply the second played an octave higher.
Why use suspended chords?
Most progressions use just major and minor chords. A suspended chord holds the music in suspense, so the listener waits for something to happen. That creates excitement and anticipation and makes your playing more interesting.
Method 1: Add sus chords to an existing progression
Jason uses the well-known I–V–vi–IV pop progression in A major:
- A major (I)
- E major (V)
- F# minor (vi)
- D major (IV)
Suppose each chord has to last a long time. For example, A major might need to fill four bars or more. Holding one plain chord that long gets boring.
The fix is to move between each chord and its suspended versions while it lasts, for example A to Asus4 and back. The harmony stays the same, but the sound keeps moving.
Method 2: Hold a sus chord over a moving bass line
Keep one suspended chord steady in your right hand and change the bass notes underneath it.
- Jason demonstrates with Fsus4 = F Bb C.
- You can play it in different inversions, or play arpeggios on it.
- Your left hand moves through different bass notes. In a band, the bass guitarist can move the bass line while you hold the chord.
This adds another dimension to the music. It works especially well when the progression is very simple, even just two chords.
You can also base the idea on a minor chord. Queen's The Show Must Go On starts on C minor and keeps shifting between C minor (C Eb G) and Csus4 (C F G) over a changing bass line.
Method 3: Use suspended notes as melodic fills
Suspended notes can support the melody and add to what the singer is doing. While a standard progression plays, slip in short fills that move from the major chord to its suspended form and back to major.
The key is taste. Add fills only where the music needs them and don't overdo it.
How to practise
- Build sus2, sus4, sus2-sus4, 7sus4 and 9sus4 on C until you can find each one quickly.
- Play I–V–vi–IV in A, giving each chord several bars. Move each chord to its sus4 or sus2 and back.
- Hold Fsus4 in your right hand, try its inversions and arpeggios, and change the bass notes in your left hand.
- Alternate C minor and Csus4 over a moving bass to hear the minor version.
- Practise short major–sus4–major fills between melody phrases, keeping them sparing.
Questions about this lesson
What is the difference between sus2 and sus4 chords?
Both replace the chord's third. A sus2 chord uses the second (C D G), while a sus4 chord uses the perfect fourth (C F G).
Can I add a seventh to a suspended chord?
Yes. Over a sus4 chord you can add a major seventh or a minor (dominant) seventh, such as C F G Bb, and you can add a ninth on top for an even richer colour.
How do I use suspended chords in a pop progression?
When a chord lasts several bars, move between it and its suspended versions, for example A to Asus4 and back. This keeps the harmony the same but adds movement and anticipation.
Can suspended chords be used with minor chords?
Yes. Queen's The Show Must Go On alternates C minor and Csus4 over a changing bass line.
