Jazz subgenres are distinct styles within the broader genre of jazz music, each with its own unique characteristics and influences. Some popular subgenres include bebop, known for its fast tempos and complex harmonies, and smooth jazz, which features a more laid-back, melodic sound. These variations allow musicians to express their creativity while appealing to different audiences. Another notable subgenre is free jazz, which emphasizes improvisation and often breaks traditional musical structures. Artists like Ornette Coleman and John Coltrane have made significant contributions to this style, pushing the boundaries of jazz and exploring new sonic possibilities. Each subgenre enriches the jazz landscape, showcasing its versatility and depth.
