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.

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.
