“American Music” is an iPhone and Android application that uses contextual geolocation data as a kind of musical notation, creating a generative soundtrack to accompany everything from cross-country trips to short drives to the mall. The application uses the often repetitive landscape of American roadways (gas stations, fast food franchises, auto dealerships, etc) as a means to develop musical themes and figures. Patterns emerge as the application passes geodata information about nearby businesses, attractions, landmarks, and traffic features through a series of sound synthesis modules. Specific places acquire unique “sound signatures” that are sequenced and layered by the user’s passage through space. The result is a dynamic musical representation of 21st century American landscapes.
