Well, it is certainly not in concert halls. Not only are these events very expensive (also in upkeep for the cities), but they are only showing-off events for snobs.
IF classical music wants to survive and thrive, it has to shrug off this formalized version. There are several ideas on how to get this music back to the people. One is of course to give cheaper concerts in surprising new venues (open air, on festivals or on the street). Some orchestras are experimenting with these kind of new “marketing” strategies, drawing bigger crowds and getting people emotionally involved and interested.
The other way is and will be Film sheet music. Here we see the best composers of our time. We know the tunes of Indiana Jones or Star Wars better than those of Beethoven’s 9th. Film music is made for the people while still retaining the qualities of classical music. It is not made to entertain snobbish upper class pretend listeners.
And now, aside of movies, we also have Videogames. I am increasingly surprise about the influences of classical music in video games and how they produce tunes that are as memorable as a Mozart or a Bach.
