I think that musicians, especially performers, must regularly re-invent and renew their expressions of excitement and advocacy of classical music. The gap is wide between our (performers') understanding and love of the music we play, and the level of appreciation for it from most audience members. Yet however much we would like our patrons to educate themselves about the music, it is really our responsibility to make the connection to them.
Emphasis mine in quote below.
For decades, classical music has been in lugubrious decline. Classical music may be old, but it isn't for old men. The music survived because it is some of the best work humans have done in four centuries. For the thrill of a late-Beethoven trill, it's worth getting past the admittedly stuffy, stagey conventions.
