Norman Lebrecht relays concerns that UK orchestras are in critical condition which is yet another reason I doubt that the future of "classical music" is likely to take a symphonic form now that a pandemic is gutting concert life as we've known it in the classical scene

With the global pandemic situation gutting concert life it's not a surprise that Bachtrack has closed shop

Sympathetic as I am to the cause of continuing what's generally called "classical music" I have had my doubts, and posted them here at my blog, over the last year or so that whatever the future of classical music is that it will necessarily take the form of the symphony.

I.e. the name Future Symphony Institute might put too much stock in there being symphonies in the future.  I don't think for a second that "a renaissance for classical music means a renaissance for humanity".  That seems like the kind of "fine art makes you a fine person" kind of manifesto that Richard Taruskin has spent his entire professional career, more or less, arguing emphatically against.

On the other hand, per some pieces by Jay Nordlinger at the Future Symphony Institute website, that were published in The New Criterion (back when I bothered to even read that magazine, come to think of it), mentioned way back circa 2004 some points raised more recently at On an Overgrown Path back in 2014 (there's too much classical music in terms of market saturation):

We have a glut problem, however. Horne recalls saying fully twenty-five years ago, “We should close all the conservatories for five years,” just to give the job market a break. And “now the situation is worse!” For woodwind and brass players, life has always been tricky: Zarin Mehta tells me that, for a recent tuba opening in the Philharmonic, over 120 people applied. [Editor’s note: A current tuba opening at the Baltimore Symphony Orchestra has over 180 applicants.] One result of all this redundant talent is that players tend to be quite good, everywhere. David Delta Gier, a conductor with wide experience both in America and abroad, says, “You should hear some of the players in Sioux Falls!” (The orchestra there is the South Dakota Symphony.) The sad part of our cornucopia is that many musicians wind up disappointed. Gier knows many fellow conductors – or would-be conductors – who have not had careers, or satisfying ones, simply because of the number of podiums available (versus all those who want to stand on them). “You get into a great school, you study with a great teacher, you work hard, you do everything right, and you think you ought to be rewarded. But a lot of people have been made to realize that that’s not necessarily the case.”

In a pandemic scenario even an orchestral conductor has pointed out the obvious, that symphonic music is not necessarily "what we need" these days.  Chamber music may be better able to withstand the current tide of policies that have curtailed concert life.  

Actually, that kind of gets me back to why I think Douglas Shadle is basically wrong about the idea of canceling the nineteenth century.  In a global pandemic we might want to actually revisit the Biedermeier era of in-house music-making.  I'm a classical guitarist interested in solo guitar music and particularly chamber music that includes the guitar so, of course, I don't see any reason we should "cancel the nineteenth century" when it was during the 1810 to 1845 period or thereabouts that guitarists were writing the kind of DIY music for amateurs playing solo and chamber music of the sort that we could learn from if the global covid-19 pandemic situation has led to policies that may 
permanently damage concert life at the orchestral and symphonic levels.  You can still play Chopin or even Beethoven (or Dussek or Hummel) in the privacy of your home, just like you can play blues, jazz standards or ragtime.  

When the Thirty Years War raged along Heinrich Schutz didn't make a point of staying at the production level of the grander larger-scale works he did in his earlier career.  He stripped everything down to little sacred concert music pieces.  His Passion settings shifted into voices-only for liturgical but also practical reasons.  

The guitar music of Mauro Giuliani is still fun to play even if snooty classical music critics at The Guardian have referred to it as silly trifling music.  Frankly, as a guitarist I find it easier to bridge the gap between American popular styles (i.e. ragtime from a century ago) and classical music by way of having studied Carulli, Giuliani or Legnani.  For that matter a Bohemian guitarist composer like Matiegka also wrote works that have given me inspiration to bridge the gap between American vernacular styles and sonata forms but Italian and Bohemian and Spanish guitarist composers are generally so far off the radar for mainstream musicology it's never been a surprise to me if in the turf wars of academic music studies pop vs orchestra or salon traditions have persisted.  If there's something we guitarists could potentially do the world over, it could be to develop ways of thinking and composing and writing about music that could potentially bridge this chasm, which musicology-as-usual in the last century and a half, even including New Musicology, has rarely seemed to be interested in remedying.   If a string quartet from Haydn might even seem hard to stage these days Haydn is public domain, try transcribing.  There are ways to learn from and to continue what we find beautiful in the old even if the received ways of playing that music can be kept from us due to the exigencies of dealing with a pandemic.  

Some ideas for consideration.
