The quote 'People love what other people are passionate about' is the philosophy of 'La La Land.' The piano is the central instrument of the film, played by Ryan Gosling’s character, Sebastian. Gosling actually learned to play the piano for the film, practicing for three months. The piano’s 'Mia & Sebastian's Theme' became the emotional anchor of the film. Its simple, melancholy melody represented the conflict between their dreams and their love. This remains a legendary example of a modern movie star mastering an instrument to make the 'legend' of their character feel authentic, supporting a film's dialogue about the sacrifices made for art.
