I'm not talking about exaggerated rubato and a deliberate Liberace-style soup of genres, but is it acceptable to add some dynamics and some tiny tempo fluctuations when playing Baroque on piano to accentuate phrasing?

How much is too much?

I know that it is hard to draw a line, but I guess there *is* a limit beyond which it gets frowned upon (even if great pianists sometimes may ignore it altogether).

How *else* are you supposed to pursue musicality in Baroque repertoire on a piano?

Can anybody point to any examples (from amateurs on Youtube, perhaps?) of good and bad playing in this respect?
