has any of you changed fingerings after performing the works many times? if so, what is the usual reasoning for it? why this happens? best, tds
Well it is obviously very important if you want to make a section sound better and the current fingering can't manage it very well.
your current fingering can't manage it very well, but you used it and play the piece for many performances? why?
Asked, and answered. You change fingerings a) if you find better ones that fits your current interpretation, or b) you change your interpretation, and your fingerings as a result.
Ditto, although as tds quite rightly implied the first time you learn the piece should be treated as the ultimate because you can develop good habits from the start.
Was it Rubenstein who claimed he changed fingerings during Rondos so he could keep track of where he was?
