2207.3 (A) Musical Works Embodied in Copies
As explained in Section 2202.2, notice is optional for works published on or after March 1, 1989. Prior to that date, a notice was required when a U.S. musical work was publicly distributed in visually perceptible copies, such as sheet music or liner notes. When a notice is included on a copy of a musical work, it is considered acceptable if it appears in any of the locations described in Sections 2207.1 (A) or 2207.1 (E) or if the notice appears on the first page of the music. 37 C.F.R. § 202.2 (C) (4) (I)-(x).
