What Are Jazz Chords?
Jazz chords are essential to the genre's complex harmonic structure and rich musical texture. They often differ significantly from standard chords used in other musical styles, contributing to jazz's unique sound.
Types of Jazz Chords
- 1. **Major and Minor Seventh Chords**: These extend standard major and minor triads by adding a seventh degree.
- 2. **Dominant Seventh Chords**: A combination of a major triad and a minor seventh, creating tension that demands resolution.
- 3. **Minor Sixth Chords**: These add a sixth to a minor triad, offering a softer, more nuanced sound.
- 4. **Diminished and Half-Diminished Chords**: Used to create tension and dissonance, vital for effective resolution in jazz progressions.
The Importance of Extensions and Alterations
Jazz musicians often use extended chords (like 9ths, 11ths, and 13ths) to add depth. Altered chords, which modify specific tones, enhance the harmonic palette, making improvisation more expressive.
Conclusion
Understanding jazz chords is fundamental for anyone looking to perform or compose within the jazz genre. They not only form the backbone of jazz progressions but also allow for greater improvisational freedom, defining the essence of jazz music.
