The stipulations of Arti- cle II apply equally to the public performance of un- published musical works, or of published works in which the author has expressly de- clared on the title page or commencement of the work that he forbids the public performance.

Article X Unauthorized indirect ap- propriations of a literary or artistic work of various kinds such as adaptations, arrangements of music, etc., are specially included amongst the illicit repro- ductions to which the pre- sent Convention applies, when they are only the re- production of a particular work, in the same form, or in another form, with non-essential alterations, or abridgements, so made as not to confer the character of a new original work.

In order to enjoy the protection of this article, authors, in publishing their works, are not obliged to prohibit the public re- presentation or public per- formance of them.

Article 12 Unauthorized indirect ap- propriations of a literary or artistic work of various kinds such as adaptations, arrangements of music, transformations of a ro- mance or novel or of a poem into a theatrical piece and vice versa, etc., are specially included amongst the illicit reproductions to which the present Convention applies when they are only the re- production of such work in the same form or in another form with non-essential al- terations, or abridgements, so made as not to confer the character of a new original work.
