What is "Schedule A?"
In reference to licensing: this is a separate document attached to an agreement laying out the details the agreement states will be included in the schedule for example publishing details, media terms, etc. In reference to administration: this is a document that lists out all of the compositions for the songwriter, all of their co-writers, all of their shares, and PRO affiliations. The writer would deliver this schedule to their administrator listing out all of the songs the administrator will be representing so they can upload into their copyright database.
