What is Quartal Harmony?

Quartal Harmony is a harmonic system in which chords are built primarily using intervals of fourths rather than the traditional thirds. It is known for its open, modern sound and distinctive tonal color.

The style typically features stacked perfect or augmented fourths, creating chords that sound less resolved and more ambiguous compared to traditional triadic harmony.

Quartal Harmony emphasizes texture and spacing, often producing a spacious, floating quality that differs from conventional chord structures.

The music is commonly found in jazz, contemporary classical, and film scoring, where it is used to create modern, atmospheric, or tension-filled harmonic landscapes.

Today, Quartal Harmony remains an important tool in modern composition and improvisation, valued for its versatility and its ability to expand beyond traditional harmonic frameworks.
