(1) A charlatan posing as a trumpet instructor who offers no educational benefit to the student. (2) One who assigns etudes without offering help of how to play them. (3) One who checks off etudes each lesson regardless of the student's progress.
Charlie didn't help me learn how to play the trumpet, he just listened and checked off the etude and assigned another one for next week, since he isn't a real trumpet teacher, but an etude-checker.
