I would like to pose this question to those who have already done something like this (for my part, I am already thinking of doing it and that's it, since it doesn't change anything at all):
after having deposited a piece, since the transposition of a part is necessary (and therefore everything else, we are talking about a piece for piano and mezzo-soprano), is a new deposit necessary or not, given that precisely, not even a single note in the score changes, but only the key?
I asked SIAE (which I think will respond tomorrow) but I have partly answered myself: I transpose it if necessary (now) and leave unchanged the "version"
that I deposited, because I am also thinking of those situations where a piece is transcribed for another instrument; the first remains the same, and at most, in the case of
a transposing instrument, it is necessary to indicate the appropriate accidentals in the clef for the latter (in that case, the "situation" changes a bit).
Thank you
