2.2 The Birth and Evolution of Jazz

Jazz emerged as a unique American art form, blending African and European musical traditions. Born in the cultural melting pot of New Orleans, it evolved from work songs, blues, and ragtime into a sophisticated genre characterized by improvisation and syncopation.

From its early Dixieland roots, jazz grew into diverse styles like swing, bebop, and cool jazz. As it spread across America, jazz was shaped by technological advancements in recording and broadcasting, allowing it to reach wider audiences and influencing popular culture.
