Characterized by its swing and blue notes, jazz often features improvisation, allowing musicians to express their creativity and individuality. Instruments commonly used in jazz include the saxophone, trumpet, piano, and double bass. Notable figures in the genre include Louis Armstrong, Duke Ellington, and Miles Davis.
