co-written definition
co-written means that all the Writers agree that the Work has been created jointly – known as a “joint work" – and that the rights are divided in accordance with the agreement even though, for example, only lyrics or a melody is being performed/published. The opposite of co-written is where a composer uses existing lyrics or a writer writes lyrics for an existing melody. This is called a composite work. The permission of the other rights-holders and the new melody must then be obtained and the new melody/lyrics will be considered as non-exclusive, and a separate enclosure should be drawn up.
