Opera was and still is one of the oldest forms of entertainment. It's been around longer than any other art form known to mankind, longer than radio, the internet, video games, television and even movies. It's an art form in which singers and musicians perform a dramatic work combining a script called a libretto and musical score, usually in a theatrical setting. Opera incorporates music, singing, scenery, costumes and sometimes dancing. Some operas have spoken dialogue called a Singspiel in which the singers talk between songs aka arias. Other operas have a singing style called a Recitative in which the singers imitate spoken dialogue by singing their lines instead of talking.
