I'd like to start giving people the option of commenting on shorter Cold Takes pieces (which I don't cross-post here or provide audio for). I'm going to use this post for that: I will generally leave a comment for each piece, and people can leave their comments as replies to that.
Why is it wrong to credit past art for innovations that have since become commonplace? If a musician's innovations became widespread, I would count that as evidence of the musician's skill. Similarly, Euclid was a big deal even though there are millions of people who know more math today than he did.
This sounds like an extreme overstatement, at least if applied to classical music. Some modern classical music it is pretty good, and better than Beethoven's less-acclaimed works. And the best of it is probably on par with Beethoven's greatest hits. But much of it is unmemorable—premiered, then mercifully forgotten. The catalog of the Boston Modern Orchestra Project is representative of modern classical orchestral music, and I think most of it falls far short of Beethoven's best symphonies. The concertgoing public strongly prefers the old stuff, to the consternation of adventurous conductors.
