An urtext edition, of a work of classical music is a printed version intended to reproduce the original intention of the composer as exactly as possible, without any added or changed material. Other kinds of editions distinct from urtext are facsimile and interpretive editions, discussed below.

Early music generally comprises Medieval music (500–1400) and Renaissance music (1400–1600), but can also include Baroque music (1600–1750). Originating in Europe, early music is a broad musical era for the beginning of Western classical music.
