Jeremy (1973)

Jeremy Jones is learning cello at an arts school in New York and spots Susan Rollins, who's practicing for a ballet audition, and he falls in love at first sight. He's very shy about approaching her, so he gets help from his experienced friend Ralph. Susan's first impression of him isn't the best--until she hears him play the cello. The movie paints a quiet image of him winning her heart, and of the development of their relationship.
