3 Techniques Brian Eno Used to Create Music for Airports' Shifting Textures

Tape loops of varying lengths Eno ran multiple tape loops at different lengths simultaneously, so the same notes combined differently on each pass.

Minimal melodic material Each loop carried simple, sparse notes, allowing the overlapping patterns to generate complexity without clutter.
