A sub-publishing deal occurs when a publisher enters into an agreement with another publisher to administer and license copyrights from their writers in a foreign market. European music publishers can sub-publish American music and vice versa. Usually these deals are done company-to-company. A very small publisher in the U.S., for example, may sign a sub-publishing deal with one of the majors to cover administration in foreign territories.

There is a perception that performing and practicing music are two very different activities. I think that the relationship between performing and practicing is deeply intertwined and at a certain level the distinction between the two virtually disappears.
