Extended chord structures

Definition

Extended chord structures refer to chords that include additional tones beyond the basic triad, often incorporating the seventh, ninth, eleventh, and thirteenth degrees. This richer harmonic palette allowed early jazz musicians to create more complex and colorful sounds, bridging the gap between the rhythmic precision of ragtime and the improvisational freedom of early jazz.
