Well, it is an anachronism. Of sorts. It is not, however, in my view at least in the same category as using the sustain pedal in Bach. The difference is that if the thing is working right, it holds the damper off on only those specific notes (or that note), just as though you were holding the key or keys down, while the sustain pedal holds all the dampers off for the whole instrument -- and changes the tone quality as well as giving ample opportunity to muddy things up. The sostenuto pedal, however, is rather tricky to use correctly, or at least I find it so -- and I use it only when I simply can't hold the note or notes in question with a stray finger or two (a rather nice example being a bit of fluff I'm working on at the moment -- the Sibelius Impromptu #4, in e minor).It is rather important to remember, however, that if you do become accustomed to using it for something, and you then want to play that something on some other piano, that not all pianos have the sostenuto pedal -- nor does it work reliably on all the pianos that do have it. Which is something to check on...
True, all true...thanks for your insights....you know, I don't really understand why I felt the need to create this thread and ask this question, yet I did. Maybe I'm still struggling with myself about the value of period authenticity. I used to think that the idea had little merit, and that we should always take advantage of what we have, that's just our duty as instrumentalists. But after listening to performances on period instruments, and performances inspired by period instruments, I also acknowledge that the instruments pose unwritten constraints upon performance, constraints that can often be illuminating.Thanks again.
This thread brings up another question to me. How come Moonlight Sonata shows pedal markings?
