Quartal harmony is a musical concept that has significantly influenced contemporary music. It involves building chords and harmonies using intervals of fourths rather than the traditional thirds, creating a distinctive sound that is often described as modern, open, and ambiguous.
Understanding Quartal Harmony
Quartal harmony is based on stacking perfect fourths or other fourth intervals to construct chords. Unlike tertian harmony, which stacks thirds to form chords like major and minor, quartal harmony emphasizes intervals of four semitones, resulting in a different harmonic texture.
Historical Development
The use of quartal harmony can be traced back to early 20th-century composers such as Igor Stravinsky and Arnold Schoenberg. It gained prominence in jazz and modern classical music, where composers sought new sonic possibilities beyond traditional tonal harmony.
Characteristics of Quartal Chords
- Built primarily on perfect fourths or augmented fourths.
- Often sound open, ambiguous, and less rooted in traditional tonality.
- Can be combined with traditional harmony for rich textures.
- Used to create tension, color, and modern soundscapes.
Applications in Contemporary Music
Quartal harmony is prevalent in jazz, where it forms the basis of modal jazz and modern improvisation. It is also common in film scores and experimental music, providing a sense of openness and fluidity.
Jazz and Improvisation
Jazz musicians often use quartal voicings to add modern flavor to their improvisations. These chords facilitate smooth voice-leading and create a spacious harmonic environment.
Classical and Film Music
Contemporary composers incorporate quartal harmony to evoke a sense of mystery, tension, or modernity. Film scores frequently utilize quartal chords to enhance emotional impact and atmosphere.
Creating Quartal Harmony
To build quartal chords, start by stacking perfect fourths or augmented fourths. For example, a C quartal chord might include the notes C, F, and B, forming a series of perfect fourths.
- Choose a root note.
- Stack fourths upward or downward.
- Experiment with different inversions and voicings.
- Combine with traditional harmony for contrast.
Conclusion
Exploring quartal harmony opens new avenues for understanding and creating modern music. Its unique sound and versatility make it a valuable tool for composers, performers, and students interested in the evolution of harmonic language.
