Subject: Re: [AUDITORY] Natural experiment example needed From: Douglas Scott <jdmusictuition@xxxxxxxx> Date: Sat, 5 Apr 2025 09:01:44 -0400--000000000000db54480632087434 Content-Type: text/plain; charset="UTF-8" Hi David What comes to mind immediately is the drop-off in live and community music making in the period. I would surmise that there would have been a big spike in headphone sales, especially as people increasingly cut the cable and move to individual streaming services. I think it was a general trend that people moved away from shared experiences to curated individualized experiences, very much in the same way as social media does in other spheres. One analogue I can think of is between someone who learns music from a score in a practice room versus someone who learns as part of a cast of a big production, and all the gradations between.
