The dramatic author and the musical composer receive recompense for their creative labor not so much from publication of their works in the printed form of a book as through their performance or representation, when protected as playright or performing right, as the artist receives remuneration not only for the reproduction and sale of copies, but also from the exhibition as well as sale of his original work. Dramatic and musical copyright, in the wide sense, therefore, covers copyright in the specific sense and playright, as to which latter common law rights especially need statutory protection. {Sidenote: American provisions} In the protection of dramatic and musical compositions the new American code specifically provides not only for copyright, but for playright or right of performance. Under subject-matter of copyright (sec. 5) such works are classified as "(d) Dramatic or dramatico-musical compositions; (e) Musical compositions"; and the Copyright Office Rules and Regulations further define these classes as follows: {Sidenote: Copyright Office definitions} "8. _(d) Dramatic and dramatico-musical compositions_, such as dramas, comedies, operas, operettas and similar works. "The designation 'dramatic composition' does not include the following: Dances, ballets, or other choregraphic works; tableaux and moving picture shows; stage settings or mechanical devices by which dramatic effects are produced, or 'stage business'; animal shows, sleight-of-hand performances, acrobatic or circus tricks of any kind; descriptions of moving pictures or of settings for the production of moving pictures. (These, however, when printed and published, are registrable as 'books.') "9. _Dramatico-musical compositions_ include principally operas, operettas, and musical comedies, or similar productions which are to be acted as well as sung. "Ordinary songs, even when intended to be sung from the stage in a dramatic manner, or separately published songs from operas and operettas, should be registered as musical compositions, not dramatico-musical compositions. "10. _(e) Musical compositions_, including other vocal and all instrumental compositions, with or without words. "But when the text is printed alone it should be registered as a 'book,' not as a 'musical composition.'" {Sidenote: Rights assured} To dramatic and musical authors are given (sec. 1) in addition to the general right, granted in subsection "(a) To print, reprint, publish, copy and vend the copyrighted work," the specific exclusive rights: "(b) ... to dramatize it if it be a non-dramatic work; to convert it into a novel or other non-dramatic work if it be a drama; to arrange or adapt it if it be a musical work;... {Sidenote: Dramatic rights}
