Sheet Music Distribution System

A system that enables digital distribution of copyrighted sheet music-and allows musician to view the copyrighted sheet music on personal computing devices-while preventing the unauthorized distribution of copyrighted sheet music. An electronic commerce platform provides functionality to purchase copies of copyrighted sheet music. A network security module provides login credentials for purchasers and musicians (and, in some embodiments, limits the number of simultaneous logins). A graphical user interface provides functionality for each purchaser to distribute each purchased copy to one-and only one-musician. In some embodiments, the system allows purchasers to recall sheet music distributed to a first musician and distribute the recalled sheet music to a second musician (without providing functionality for the first musician to view the recalled sheet music).
