Get the jmug. an imaginary musical note, which, under ideal circumstances, does not exist; a J# (jay sharp) is any musical note that should be played # (sharp) according to the key signature of the musical selection, but is (unintentionally) played as natural by the player, which will oftentimes be young and inexperienced, or careless.
Frustrated by the number of missed key signature notes, the director yells, "Don't forget your J#s!"
