Teosto is a non-profit organisation founded in 1928 by composers and music publishers, to administer and protect their rights. At Teosto, decision-making power lies with ordinary members Đ that is, music authors. Today, Teosto represents more than 32,000 Finnish and almost three million foreign composers, lyricists, arrangers and music publishers. TEOSTO acts as a link between two customer groups, music authors on the one hand and companies and communities that use music on the other. They make life easier for users of music by providing music licences in a centralised manner at Teosto, eliminating the need to make individual agreements with each music author. Their overall goal is to enable successful professional music-making in Finland. This also includes promoting the rights of music authors and music publishers, as well as diversity in and awareness of Finnish music in Finland and abroad.
Music Publishing is the business of protecting and promoting song copyrights and collecting the royalties that these copyrights generate. Think of a song as intellectual property (it's an original piece of art!), and music publishing as the business that makes sure that songwriters get paid a fair compensation when their intellectual property is used by companies. Those companies could be record labels (mechanical royalties), radio stations, bars, and restaurants (performance royalties), or film studios and advertising agencies (sync license fees), and many more.
