An encore is an additional performance added to the end of a concert, from the French encore, which means "again", "some more"; multiple encores are not uncommon. Encores originated spontaneously, when audiences would continue to applaud and demand additional performance from the artist after the concert had ended. In some modern circumstances, encores have come to be expected, and artists often plan their encores. This is sometimes necessitated by noise curfews at venues, which may also sometimes require an artist to forgo encores if the concert has gone on too long. Traditionally, in a concert that has a printed set list for the audience, encores are not listed, even when they are planned.
Though the word derives from French, encore was traditionally not used this way in French, nor ancora in Italian. French speakers commonly use instead either une autre, un rappel or the Latin bis in the same circumstances. Italians also use bis and, formerly, da capo.
