Consider The Waveform

“What visual sign says ‘music’? Notes remain the most typical answer — particularly, it seems, beamed eighth or quarter notes (see the iTunes icon); the solitary eighth note with its jaunty flag; and the clef. The disc shape has had a pretty good run, and you still see instances involving headphones (Napster’s logo, for instance). Maybe representations of speakers and guitars would make the list, too. But if you want to suggest music in the digital era, how about the waveform?”
 — Well? How about it?
