A Music publisher can refer both to an organization that secures and manages copyrights for musical compositions and to the person who runs it.
Their tasks include promoting their catalog’s songs to recording artists; licensing compositions for use by films, television, advertisements, and other media; monitoring song usage; and collecting and distributing royalties to clients. Music publishers administer all the various revenue streams that flow toward songwriters and composers, each of which has a separate, complicated, and shifting fee structure. Other duties include clearing material to ensure that there is no copyright infringement attached to the catalog and having compositions transcribed to print.
