Translations of sung texts—whether of the above type meant to be sung or of a more or less literal type meant to be read—are also used as aids to audiences, singers and conductors, when a work is being sung in a language not known to them. The most familiar types are translations presented as subtitles or surtitles projected during opera performances, those inserted into concert programs, and those that accompany commercial audio CDs of vocal music. In addition, professional and amateur singers often sing works in languages they do not know (or do not know well), and translations are then used to enable them to understand the meaning of the words they are singing.

The bibliographer Ronald B. McKerrow introduced the term copy-text in his 1904 edition of the works of Thomas Nashe, defining it as "the text used in each particular case as the basis of mine." McKerrow was aware of the limitations of the stemmatic method, and believed it was more prudent to choose one particular text that was thought to be particularly reliable, and then to emend it only where the text was obviously corrupt. The French critic Joseph Bédier likewise became disenchanted with the stemmatic method, and concluded that the editor should choose the best available text, and emend it as little as possible.
