How to Play Suspended Chords on Piano

Suspended chords, commonly referred to as “sus” chords, are a staple in modern music, offering a unique, unresolved sound that adds tension and color to chord progressions. Unlike traditional major and minor chords, suspended chords replace the third of the chord with either the second or fourth scale degree, creating a sound that feels open and unresolved.  If you feel comfortable reading sheet music, dive into the PDF and start memorizing all of those shapes and knowing their names.

Understanding Suspended Chords

In a typical triad, such as a C major chord, the notes are built from the root (C), the third (E), and the fifth (G). The third determines whether the chord is major (with a major third) or minor (with a minor third). However, in suspended chords, the third is omitted and replaced by either the second or fourth note of the scale, creating two main types of suspended chords:

• Sus4 Chord: The third is replaced by the fourth.
• Sus2 Chord: The third is replaced by the second.

How to Play a Csus4 Chord

The Csus4 chord is formed by taking a C major chord (C, E, G) and replacing the third (E) with the fourth note in the C major scale, which is F. The notes of a Csus4 chord are therefore C, F, and G. The Csus4 chord creates a sense of tension and anticipation, often leading back to the C major chord for resolution.

How to Play a Csus2 Chord

The Csus2 chord is created by replacing the third of the C major chord with the second note of the C major scale, which is D. The notes in a Csus2 chord are C, D, and G. The Csus2 chord has a lighter, more ethereal sound compared to the Csus4, and like the sus4 chord, it often resolves back to the C major chord.

When to Use Sus Chords in Your Playing

Suspended chords are incredibly versatile and can be used in various musical contexts:

• Creating Tension: Both sus4 and sus2 chords introduce tension, making them perfect for transitions in chord progressions.
• Adding Variety: Instead of playing the same major or minor chords repeatedly, sus chords can add a refreshing twist to your music.
• Open Sound: The lack of a third in sus chords gives them an open, airy sound, which can be ideal for softer or more contemplative pieces.

Conclusion

Understanding and using suspended chords like Csus4 and Csus2 can elevate your piano playing by adding depth and complexity to your music. By replacing the third of a major chord with the second or fourth, you can create a sound that is both familiar and intriguingly different. Whether you’re looking to add tension, create variety, or achieve an open sound in your compositions, sus chords are a powerful tool to have in your musical toolkit.
