Title: Humoresque (1946)
Genres: Drama, Music, Mystery
Description: Paul Boray comes from a working class background. He has been interested in the violin since he was a child, which his father disliked since he felt it a waste of money, but which his mother supported. Into his adult life, Paul wants to become a concert violinist, and although he shows talent, he does not have the right connections to make it into the concert performance world, much like his longtime friend, virtuoso pianist Sid Jeffers, and cellist Gina, both who, like Paul, train with the National Institute Orchestra. Gina and Paul have a connection with each other, Gina who confesses her love for him. While performing at a party with Sid, Paul meets Helen and Victor Wright, their hosts. Victor is a perceptive but self-admittedly weak man, while his wife Helen is strong minded but insecure which manifests itself as neurosis. She constantly tries to forget about her unhappy life by excessive alcohol consumption. Helen becomes Paul’s benefactress, which ultimately results in a successful concert career for Paul. But the two also fall in love, a destructive love against the wishes of Paul’s mother and Gina. That love may not only destroy Paul’s concert career, but their lives as well.
