"(e) To perform the copyrighted work publicly for profit if it be a musical composition and for the purpose of public performance for profit; and for the purposes set forth in subsection (a) hereof, to make any arrangement or setting of it or of the melody of it in any system of notation or any form of record in which the thought of an author may be recorded and from which it may be read or reproduced"--which last clause is, however, limited by an elaborate proviso requiring the licensing of mechanical musical reproductions in case the copyright proprietor permits any reproduction by that means, which proviso is given in full in the chapter on mechanical music. {Sidenote: Previous American law} The American law previously defined the scope of copyright (Rev. Stat. sec. 4952), as "the sole liberty of printing, reprinting, publishing, completing, copying, executing, finishing, and vending the same; and, in the case of a dramatic composition, of publicly performing or representing it, or causing it to be performed or represented by others. And authors may reserve the right to dramatize or to translate their own works." The new code is both broader and more definite. {Sidenote: Unpublished works} The new American code is specific in preserving to an author previous to the publication of his work all common law rights in the comprehensive language (sec. 2): "That nothing in this Act shall be construed to annul or limit the right of the author or proprietor of an unpublished work, at common law or in equity, to prevent the copying, publication, or use of such unpublished work without his consent, and to obtain damages therefor." {Sidenote: Common law scope} In the Washburn form of the copyright bill it was proposed to include a clause to the effect "that subject to the limitations and conditions of this Act copyright secured hereunder shall be entitled to all the rights and remedies which would be accorded to any other species of property at common law." But this provision was not accepted by the Congressional Committees and does not form part of the copyright code as enacted. {Sidenote: Common law in U. S. practice}
