Drexel 3976, also known as The Rare Theatrical (based on an inscription from a former owner), is a 17th-century music manuscript compilation of works by the composer Matthew Locke, considered by some to be "the father of all Restoration dramatic music." The manuscript is a significant source of Locke's instrumental dramatic music with many works not known through any other source, although the contexts of the individual works and the names of the plays which they are from has not been documented.
