Before 1950, jazz evolved through several distinct styles, starting with ragtime, characterized by its syncopated rhythms and piano-driven melodies. The blues introduced a deeper emotional expression, influencing various jazz forms. Swing emerged in the 1930s, emphasizing big bands and danceable rhythms, while Dixieland, rooted in New Orleans, featured ensemble improvisation and a lively, joyous sound. By the 1940s, bebop arose, focusing on complex harmonies and faster tempos, paving the way for the later development of cool jazz, which emphasized relaxed tempos and subtlety.
