Jazz music is a genre of music that originated in the United States in the late 19th and early 20th centuries. It is characterized by improvisation, syncopated rhythms, and the use of various instrumental techniques such as brass, woodwinds, and percussion.

Jazz music has its roots in African American musical traditions such as blues and ragtime, as well as European harmonic structures. Over the years, jazz has evolved into various sub-genres, including swing, bebop, cool jazz, free jazz, and fusion.

Jazz music is often associated with live performances in small venues such as clubs and bars, although it has also been performed in larger concert halls and festivals. Many famous jazz musicians have emerged over the years, including Louis Armstrong, Duke Ellington, Charlie Parker, Miles Davis, John Coltrane, and Ella Fitzgerald, among many others.
