West Coast jazz

West Coast jazz refers to styles of jazz that developed in the American West Coast cities of Los Angeles and San Francisco during the 1950s. West Coast jazz is often seen as a subgenre of cool jazz, which consisted of a calmer style than bebop or hard bop. The music relied relatively more on composition and arrangement than on the individually improvised playing of other jazz styles. Although this style dominated, it was not the only form of jazz heard on the American West Coast.
