On the other hand some Bach's keyboard concertos and violin concertos are the same concertos, just the lead instrument is different. That is just one example how Bach recycled his music.
Is it annoying to play a keyboard concerto as a violin concerto or vice versa if Bach himself did so?
Is it annoying to play a keyboard concerto with piano instead of harpsichord? Bach himself thought it is OK to play it with violin which certainly differs more from harpsichord than piano..
If Bach himself did not "respect the score" why musicians should?
I hear you.
But this discussion is not exactly what I meant. If you want to know what Rodrigo's point is/was: you'll have to ask him. All we remember is that somewhere he stated that in Bach the piano was getting more annoying to him during the years.
But IMHO such isn't necessarily an opinion, ruled by strict HIP-thinking, or what Bach would have thought of something. I never met this guy called JS, and he never knew a Steinway, so I really can't say anything about his thoughts concerning the use of an instrument that he never knew himself.
If someone wants to play a saxophone concerto on a Krummhorn or even on a piano, he/she should do that. No problem to me. I even might like it better. But to me, personally, the piano doesn't work that well in Bach's music. The sound is just too 'broad' to me. Which doesn't mean that I never listen to Bach on the piano. I even try to play some Menuetto's, Musettes and Bourrées myself, on my terrible instrument at home.
When I talked about 'respecting the score' I was referring to a serious attempt to make music out of it, with at least some serious knowledge of the 'baroque' background (whatever that is, scholars seem to differ in their opinion

). But I wasn't thinking of making use of the historical 'correct' instrument.
Apart from that, I don't think that rebuilding old piano's to make them somehow sound like harpsichords can be taken seriously. Mengelberg did that to use piano's in the basso continuo, but in his time there weren't that many decent harpsichords. Although I think that, had he heard one, he still would have detested it.
But it's different with Gould's recording of the
Inventionen. If he wanted the sound of a harpsichord, my suggestion would have been: play one. From the sixties on, there was a growing interest in this instrument, which resulted in some good sounding ones.
Now Gould was playing this nice music on some kind of a 'hickup' piano. To be honest: it makes me laugh.
I prefer his renderings of f.i. the Goldbergs, and take them more seriously .... if only he would have respected more repeats! But that's mainly because I like the composition that much.
