Karaoke (カラオケ^?, portmanteau of Japanese kara 空 "empty", and ōkesutora オーケストラ "orchestra") ( /ˌkæriːˈoʊkiː/; Japanese: [kaɽaoꜜke] ( listen)), also known as Minus-One in the Philippines, is a form of interactive entertainment or video game in which amateur singers sing along with recorded music (a music video) using a microphone and public address system. The music is typically a well-known pop song minus the lead vocal. Lyrics are usually displayed on a video screen, along with a moving symbol, changing color, or music video images, to guide the singer. In some countries, a karaoke box is called a KTV. It is also a term used by recording engineers translated as "empty track" meaning there is no vocal track.

The concept of creating studio recordings that lack the lead vocal has been around for nearly as long as recording itself. Many artists, amateur and professional, perform in situations where a full band/orchestra is either logistically or financially impractical, so they use a "karaoke" recording; they are, however, the original artists. (This is not to be confused with "lip synching," in which a performer mimes to a previously produced studio recording with the lead vocal intact.)
