I think nobody mentioned a french movie from the 80s with young sophie
marceau (not sure about the spelling)-la boum(e) (again not sure about
the spelling)- where sophie´s aunt is a harp teacher! so there are a
few scenes with the harp.
there is also a movie with john malkovich and joung uma thurman
“Dangerous Liaisons” where uma thurman is learning how to play harp- it
is a movie about the french royal class just before the french
revolution.
