How to Write Progressions with Quartal and Quintal Intervals in DAWs

by

Creating musical progressions using quartal and quintal intervals can add a modern and open sound to your compositions. Digital Audio Workstations (DAWs) provide powerful tools to experiment with these interval structures seamlessly.

Understanding Quartal and Quintal Intervals

Quartal intervals are built on the perfect fourth, which spans five semitones. Quintal intervals are based on the perfect fifth, spanning seven semitones. Both are used to create spacious, ambiguous, and contemporary harmonies.

What is a Quartal Interval?

A quartal interval is any interval of four notes stacked in intervals of a perfect fourth. For example, C to F (C-F) is a perfect fourth, and stacking these creates quartal harmony.

What is a Quintal Interval?

A quintal interval is based on stacking perfect fifths. For instance, C to G (C-G) is a perfect fifth. These intervals form the foundation of quintal harmony, giving a strong, stable sound.

Writing Progressions in DAWs

Using your DAW, you can craft progressions with quartal and quintal intervals by constructing chords and melodies that emphasize these structures. Most DAWs allow you to input MIDI notes directly or use chord tools to facilitate this process.

Step 1: Choose Your Root Note

Select a root note that will serve as the foundation for your progression. This note will anchor your quartal or quintal chords.

Step 2: Build Quartal and Quintal Chords

Create chords by stacking perfect fourths or fifths above the root. For example:

  • C – F – Bb for a quartal sound
  • C – G – D for a quintal sound

Step 3: Sequence Your Progression

Arrange these chords in a sequence that moves smoothly or creates tension. Experiment with different inversions and voicings to add variety.

Tips for Effective Use

To maximize the effect of quartal and quintal progressions:

  • Use open voicings to emphasize intervallic relationships.
  • Combine with modal or ambiguous scales for a modern sound.
  • Apply automation to create dynamic movement within your progressions.

Conclusion

Incorporating quartal and quintal intervals into your DAW projects opens up new harmonic possibilities. Experiment with stacking these intervals to craft unique progressions that stand out in contemporary music production.
