The quote 'I'm walkin' here!' is a legendary improvised line from 'Midnight Cowboy.' To capture the loneliness of the urban sprawl, composer John Barry utilized the harmonica, played by Jean 'Toots' Thielemans. The harmonica is a free-reed wind instrument that allows for highly vocal, soulful expressions. Its wandering, melancholic melody became the 'voice' of Joe Buck and Ratso Rizzo as they struggled on the margins of society. The choice of a 'small' instrument for a 'big' city story was brilliant, emphasizing the vulnerability of the characters. The harmonica became a legend in film music, proving that a handheld instrument can carry the emotional weight of an Academy Award-winning movie and its most famous dialogue about dreams and survival.
