It's a film of highways, tourists on transhumance, concrete picnic tables, queues for toilets, warm melons and carwashes. It's the film of a man who wants to leave and a little boy who holds him back. It's the summer movie.

Music is the story of a father and son. Or, rather, the story of the reunion between a father and son who have hardly seen each other over many years and who clumsily attempt to renew bonds. Unfortunately, too much time has already passed and it will be impossible to strengthen the ties. But although they lose each other again, the father will nevertheless pass on a legacy to his son: the love of music.
