A music publisher is a company or individual that manages the rights to musical compositions. They help songwriters and composers by promoting their music, securing licensing deals, and collecting royalties when their songs are used in various media, such as films, commercials, or streaming services. In addition to managing rights, music publishers often assist in the creative process by connecting artists with songwriters and providing resources for recording. They play a crucial role in the music industry, ensuring that creators are compensated for their work while helping to bring new music to audiences.
