It may be deemed proper and it will not be denied that it would be just that a composer of a musical composition of this class who causes it to be embodied in the form of perforated roll, and who can derive a revenue from it practically only in this form, should be considered in the light of both composer and arranger, and as entitled to obtain original and independent copyright of the perforated roll, so as to control the composition absolutely in this form. It is believed that it will not be difficult to frame a provision of the statute to do justice to this class of composition, and which shall not trench upon the natural equity of the perforated roll arranger for other musical compositions, or upon the natural right of the public to derive the use of the automatic reproducing devices upon ordinary musical compositions, without requiring the consent of or paying tribute to the composer. _4. As to duration of copyright._--The bill before your committees proposes a remarkable extension of the period of copyright beyond anything heretofore granted. This is believed to be contrary to sound public policy and of doubtful constitutionality. The Constitution expressly limits the power of Congress in respect to their copyright protection to granting such protection "for limited periods." The term "limited" can have only a relative meaning, and the obvious meaning is limited with respect to or in comparison with the period during which the public will have desire or use for the copyrighted work. It is contemplated, evidently, that in compensation for the protection which the statute gives the composer for a limited period the public shall derive the unqualified use and benefit of the work for a remaining period. If there is no remaining period, the consideration for the protection has failed. It needs no statistics to establish to the common knowledge of the committee that not one book in ten thousand has any commercial value fifty years after its publication. It will probably be safer to say that not one published work in a hundred thousand has any life after fifty years. If, therefore, the author is given the monopoly for fifty years, the public has nothing left to compensate it for that monopoly and protection. Not one work in a million endures so as to have any value after one hundred years. But the bill proposes, as to the great bulk of copyrightable matter, that the period of copyright shall be substantially one hundred years--fifty years after the death of the author.
