When sight reading, are you expected to also use the fingering as displayed on the sheet? I find that it becomes much harder when doing so, as opposed to learning the notes and then revising the fingering if then I'm using akward fingering. Conversely its also difficult to relearn fingering if i'm habituated to them . I'm curious as to what advanced players do when sight reading. What happens if there are no fingerings written? Id imagine when composers wrote they didnt put the fingering down, the pianist would have to do that manually - but then how would they go about sight reading them ? Also, some of the fingers seem to be overtly complicated, should i be following them anyways as best I can in order to get good practice?
