Music Publisher: The music publisher is the business partner in a musical composition. A good music publisher has the knowledge and contacts to promote a song or composition. Typically, a publisher enters into an agreement with the songwriter, whereby the songwriter assigns partial ownership and control of their songs to the publisher, in exchange for a percentage of the income derived from the exploitation of them. A reputable publisher never charges a fee for his/her service. To learn more, review SOCAN’s Publishing 101 in the Creators’ Toolbox.
