Do you enjoy Karaoke? Karaoke just means it is only the instrumental used from the recording of a track.
I love Karaoke!  It is so much fun!  Where did it originate?
Well the karaoke concept of using instrumental only has been around for as long as the recording itself. Some people do sing-alongs with these karaoke tracks.
I thought karaoke was a Japanese thing?  Didn't it come from there?  
Originally karaoke means using the instrumental track. A lot of artists will use a karaoke track in situations where they cant utilize their full band. So they just use the karaoke track and original singer sings over it.
Oh,  I didn't realize that!  Is it popular around the world?
Sure but do not confuse karaoke with lip syncing. That is when a performer mimes over a studio recording.
That makes sense.  What language did the word karaoke derive from?
