Music for Airports is the 1978 album — formally titled Ambient 1: Music for Airports — that established ambient music as a genre and provided the paradigmatic instance of generative composition. The album's most celebrated track, 2/1, was produced by a system of tape loops of different, mathematically unrelated lengths, each carrying a single note or short phrase. When played simultaneously, the loops drifted continuously in and out of alignment, producing harmonic combinations no one composed. Eno chose the elements; the system chose the specific music. The album's liner notes articulated the founding principles of ambient music and made explicit for the first time the distinction between designing a system and composing its output.

Eno constructed the piece in a London studio using professional tape machines whose mechanical idiosyncrasies determined the loop lengths. Because no two loops were precisely equal, and because their lengths shared no common denominator, the overall pattern never repeated across any practical duration. The listener hearing a
