Karaoke is a form of singing in playback following the letter of the song printed on a screen. Etymologically, the word comes from Japanese kara (空), meaning "empty", and oke, Japanese abbreviation of the word "orchestra." This means that the singer does not need an orchestra to be present to sing.
A classic of popular culture events that could not be missed in Nihon Jaia!.
