Suspended Chords
Let’s look at how to play an Asus (A suspended) chord on the piano.
What Are Suspended Chords?
There are two main types of suspended chords: sus2 and sus4.
Sus2 chords are built using the first, second and fifth notes of the matching major scale.
Sus4 chords are built using the first, fourth and fifth notes of the matching major scale.
You can learn how to build a major scale here.
Let’s look at both types using A as the root note (the note the chord is named after).
How to Play an Asus2 Chord
To play an Asus2 chord, we’ll play the first, second and fifth notes of the A major scale: A – B – E
A – B – E

You can use this pattern to build any sus2 chord on the piano. Just play the first, second and fifth notes of the matching major scale.
How to Play an Asus4 Chord
Now let’s look at how to play an Asus4 chord on the piano. To play an Asus4 chord, we’ll play, the first, fourth and fifth notes of the A major scale: A – D – E
A – D – E

You can use this pattern to play any sus4 chord on the piano. Just play the first, fourth and fifth notes of the matching major scale.
If you see a chord labeled “sus”, without a number, it usually indicates a sus4 chord.

Conclusion
Now you know how to build an Asus chord, and you can use that knowledge to build all kinds of sus2 and sus4 chords on the piano.
Suspended chords are lots of fun to use at the piano, and work very nicely as substitutes for major and minor chords, since the only difference is the middle note. Once you start using them, you’ll find there are lots of places to include them in your music!
