This document discusses the changing nature of popular music in the digital age. It notes that digitization is about values rather than just technology. Popular music is defined broadly rather than by specific genres. The boundaries between composition, production, sound design and performance have blurred as digital tools allow new creative possibilities. Musicianship is now about more than just live performance or instrumentation, expanding to include studio production skills. Recordings can create immersive illusions that become reality themselves. Electronic music allows new ways of creating music through technology like drum machines that change patterns. New forms of visualization may further musical understanding.
