"A non-magical harmonica! Great! Magic music sounds so bland and free from error. Non-magical music has mistakes everywhere!"
—Music classroom monitor[src]

Music classroom monitor was a Ravenclaw student at Hogwarts School during the 1990s.

He attended Music classes and worked in the capacity of classroom monitor, in order to assist the professor.[3]



When Harry Potter gained possession of a harmonica during his second year, he thought he should give it to the Music Professor. Finding out he was absent from his classroom, he gave it to his assistant. In exchange for the harmonica, in return, the classroom monitor gave Harry a magic whistle.[3]


Notes and references

  1. He was at least in his third year by 1992.
  2. He was fascinated with the mistakes on non-magical music and bored with the errorlessness of magical music. This would be unlikely if he grew up around Muggles.
