Augmented major seventh chords are a fascinating and versatile harmonic device in jazz and fusion music. Their unique sound adds color, tension, and sophistication to your chord progressions. Learning how to incorporate these chords effectively can elevate your improvisation and composition skills.
Understanding Augmented Major Seventh Chords
An augmented major seventh chord is built by combining a major seventh with an augmented triad. Its formula typically includes the root, major third, augmented fifth, and major seventh. The distinctive sound comes from the augmented fifth, which creates a sense of tension and resolution.
For example, a C augmented major seventh chord (C+maj7) consists of the notes C, E, G#, B. This chord sounds both bright and mysterious, making it ideal for adding flavor to jazz and fusion progressions.
Common Voice and Notation
In jazz and fusion, these chords are often notated as C+maj7, Caugmaj7, or even C+7. Musicians should familiarize themselves with these symbols to recognize and utilize the chords effectively in various contexts.
Incorporating Augmented Major Seventh Chords into Progressions
Integrating augmented major seventh chords into your progressions involves understanding their function and how they interact with surrounding chords. They often serve as passing chords, color tones, or tension builders leading to resolution.
Using as Passing Chords
Place augmented major seventh chords between diatonic chords to create smooth, chromatic voice leading. For example, moving from a Cmaj7 to a D7 can be enriched by inserting a C+maj7 as a passing chord.
Creating Colorful Tensions
Use augmented major seventh chords to add unexpected color within a progression. For instance, inserting a G+maj7 in a ii–V–I progression can heighten interest and complexity.
Practical Examples
Here are some common progressions incorporating augmented major seventh chords:
- Cmaj7 – C+maj7 – Dm7 – G7 – Cmaj7
- Am7 – G+maj7 – D7 – Gmaj7
- Fmaj7 – G+maj7 – Em7 – A7 – Dm7 – G7 – Cmaj7
Voicing and Improvisation Tips
Experiment with different voicings of augmented major seventh chords to find the sound that best fits your style. Use voice leading principles to connect these chords smoothly. In improvisation, target the tensions created by the augmented fifth to craft expressive lines.
Incorporate scale choices such as altered scales or modes derived from the augmented chord to expand your melodic vocabulary.
Conclusion
Augmented major seventh chords are powerful tools for jazz and fusion musicians seeking to add sophistication and color to their progressions. By understanding their structure, function, and application, you can create more dynamic and engaging harmonic landscapes in your playing and composing.
