The quote 'Adventure is out there!' is the spirit of the legend in 'Up.' In the famous 'Married Life' opening, composer Michael Giacchino used the tuba to represent Carl Fredricksen. As a young man, Carl’s theme is played by a light, hopeful trumpet. As he ages and becomes more 'sturdy' and set in his ways, his theme is taken over by the tuba. The tuba’s deep, rhythmic 'oom-pah' sound captured both his grumpy exterior and his solid heart. This choice showed how an instrument can represent a character’s aging and personality shift, making the wordless opening of the movie legend feel more profound than a full page of dialogue.
