The creation of voluntary representation finds its cause in the underly- ing purpose of the management relationship. Its realization in the field of music performance is configured through the management contract established between the artist and the representative; a contractual figure where the particularities of the legal framework of voluntary represen- tation and the protection of artists, performers, and players converge. The management contract of music player representatives is a contract by which the representative agrees to render cooperation services on behalf of the artist, vital for the circulation of the performance or play, as a cultural product. These are activities the artist cannot and does not want to carry out, as he is immersed in the creative process. This is an atypical, consensual, bilateral -given its onerous character- contract, although there are no obstacles for the contract to be free, with a long term. It is also based on principles of exclusivity, mutual trust, and reciprocal loyalty.
