Jazz musicians and arrangers often seek ways to add richness, color, and texture to their compositions. One effective technique is the use of secundal chords, which are built by stacking intervals of seconds (major or minor). These chords create a distinctive sound that can transform simple progressions into complex, colorful textures.
What Are Secundal Chords?
Secundal chords consist of notes separated by seconds—either major seconds (whole steps) or minor seconds (half steps). Unlike traditional triads or seventh chords, secundal chords emphasize dissonance and tension, making them ideal for jazz harmony.
Types of Secundal Chords
- Major second chords: Built by stacking major seconds, e.g., C–D–E.
- Minor second chords: Built by stacking minor seconds, e.g., C–C#–D.
- Mixed seconds: Combining major and minor seconds for varied textures.
Using Secundal Chords in Jazz Arrangements
Secundal chords add a shimmering, modern sound to jazz arrangements. They can be used as:
- Passing chords between diatonic harmonies
- Voicings for improvisation and comping
- Colorful harmonic backgrounds for solos
Practical Tips for Musicians
To incorporate secundal chords effectively:
- Experiment with stacking different seconds to create unique voicings.
- Use them as passing or neighbor chords to add movement.
- Combine with traditional chords for contrast and interest.
By integrating secundal chords into your jazz vocabulary, you can add a new layer of color and texture, enriching your arrangements and performances.
