The 2nd movement of Beethoven’s 7th symphony really is quite breathtaking. This observation might seem a little jejune; after all, it’s Beethoven. The 7th symphony isn’t exactly obscure. (And the 2nd movement encored at the symphony’s premier.)
Nevertheless, I think it bears pointing out. A lot of “high culture” music has a good reputation, and is well represented in symphony halls and dentist’s offices, but can sometimes seem a little difficult to appreciate. This piece, however, has always had a visceral impact on me. I suggest you give it a listen. (Bonus recommendation: The piece is featured – over some striking B&W imagery – in the opening to “The Fall“, which is quite an experience in its own right.)
