Op. 27, No. 2. There’s a lot going on here. This is much slower than anyone else plays it. My contention is that in modern performance practice, we interpret metronome marks from this era incorrectly, in a way that leads us to play too quickly. I’m playing more or less according to what I believe to be an accurate reading of Czerny’s marking of quarter note = 60. Actually, I’m a tad fast, and I rush a little bit.
I understand this sounds weird to modern ears that have only heard this faster. I get that it might sound improbable. The thing is, the faster interpretation leads to pieces that are literally IMPOSSIBLE to play. Namely, the Hammerklavier sonata. All things being equal, improbably slow is still plausible, while impossibly fast isn’t. There’s certainly room for study here. But I’ll stop claiming this is authentic, when THEY stop claiming that it isn’t. Because they don’t know.
Some here have suggested that this music at this tempo is somehow agonizing. I've gotta say...I just do not find that to be the case. I don't have a problem believing this to be a 19th c Adagio. I think it's quite beautiful, actually. The 16ths v triplets makes more sense. It's easier to maintain a triplet feel in the long diminished arpeggios of the development section. In short, I find this speed regime to be absolutely workable.
Another thing I’m sticking closer to than most modern performers, is Beethoven’s performance instruction of “always without dampers.” This performance instruction makes much more sense at the slower tempo, as harmonies have more time to die out without having to clear the pedal. Nevertheless, on a modern more resonant grand, I do clear the pedal occasionally out of an attempt to get closer to what I think a fortepiano might’ve sounded like, i.e. less muddy.
Regardless of your beliefs, I hope you can enjoy the performance as much as I enjoyed playing it!
