Jazz chords are complex harmonies that add richness and depth to music. Unlike basic major and minor chords, jazz chords often include additional notes, such as the seventh, ninth, eleventh, and thirteenth. These extensions create a more colorful sound, allowing musicians to express a wide range of emotions. In jazz, chords are frequently used in progressions that create tension and resolution. Musicians often employ techniques like voicing and substitution to enhance their sound. Understanding jazz chords is essential for improvisation and composition, making them a fundamental aspect of the jazz genre.
