He handles the production, exploitation, and distribution of the scores, as well as managing all activities related to the exploitation of the intellectual property rights (copyright) of the works. Renting a score from a publisher ensures that you will have a score that is as close to the original text as possible, with no errors, and that is as legible as possible. A score can evolve depending on new interpretations and discoveries, which is why some (even the best-known operas by Verdi and Mozart) are frequently republished.
