Like I said, teenagers turned away from jazz as pop music before bebop became well known across the country. So it wasn't "oh, we can't dance to that, let's go find something else to dance to", it was "now we're all dancing to this new stuff that's not our old aunts' and uncles' music, or our parents' music", now what's this weird stuff coming out of New York City?"Is it helpful in understanding "jazz history", (and jazz wellness), to consider that Swing was music that was Dance-oriented and BeBop was meant for Listening/Digging? I've always felt that this was an important factor in the shifting "popularity" (among the mass audience) of jazz.
Once it became music for Listening, it became ripe for entry into Academia (for better or worse, or both.)
IMFO, of course.
The conventional wisdom, which seems to have been written by about five to ten jazz writers living in New York City and spending all their time immersed in jazz, in my opinion has the whole thing backwards.
As I wrote above, I'd bet that even as late as 1950, there might have been as many as 500 professional musicians playing bebop; there were probably two to three "listening clubs" in each of eight or ten major cities where the music might have been heard (Leaving NYC out of the mix, of course); compared to the tens of thousands of dance halls, National Guard armories, high school gyms, restaurants "with dancing and cocktails", etc., in every town big enough to have a gas station, all over the country, and being served by tens of thousands of musicians in local and territory bands who were still cranking it out in Goodman Lombardo Kaye Miller style. While bebop was coming to fruition, there was NO SHORTAGE of danceable jazzish music in the country. This idea that suddenly you couldn't find a way to hear (or dance to) Harry James, or the Dorseys separately or together, or Miller ghost bands, or the Elgarts, or Durwood Cline, or Jack Melick, or Mal Fitch, or Les Brown - heck - Duke Ellington, Roy Eldridge, Henry Red Allen, Coleman Hawkins, Cab Calloway - or or or, and so all there was, was "undanceable" bebop, and so young people sought out something different, just is not borne out by any kind of social history or music history.
Unless, that is, your focus is purely New York City and the cutting-edge musicians working there and you're completely unaware of the entire rest of the country.
