Singing without a live orchestra or
band. Originally meaning "without orchestra," it is a combination of Japanese "
kara" meaning "empty/bare-handed" as in "
karate", and the "okee" sound from the first syllable of "orchestra" as pronounced by Japanese.
The guy who thought up karaoke created a bar owner's dream, because as patrons provide their own entertainment by singing along with a
machine, management saves a fortune by not hiring
talented musicians.
