This movement (currently on the grade 6 list A and one of my candidates for replacing the piece I don't like) has a fair few grace notes scattered through it, and I wanted to check if anyone knew, are they supposed to be appogiaturas or acciacaturas (and I think I've spelled those both wrong but I'll leave it for the correcting delight of my fellow pedants *grin*)

They're all marked as you'd expect apog.s to be, ie no strike through, but then again many of them are semiquaver ones and they aren't always written with a strike through, and sometimes they seem to be written differently for baroque-type music anyway. So I just wanted to check! I'm trying to do a bit of work on it this afternoon so I can go to my teacher tomorrow and say "I've done a little work on this and I like it, I'd like to do it alongside the CPE" so i'm not just starting from scratch, unless it turns out she has any other possibles "up her sleeve". Fortunately it doesn't seem to evil notewise so I think it wouldn't take TOO long to catch up on it, and I do actually LIKE the piece which makes for more efficient and committed practising...

Depending which edition you have they are marked differently. I play most of them as appoggiaturas - I shall have to check now which ones are which! Do you have a recording to listen to as this would give you a guide.

I'd like to have a go at learning it before I listen (I do have it on an old exam cd) otherwise I might just end up copying it. But might resort to that if I can't decide which sound better

I definitely played them as appoggiaturas, although I think there's lots of room for personal interpretation. I'd probably listen to the exam CD if I wasn't sure about a piece, but I passed that Siciliano with 26 (I think!) playing them as appoggiaturas. Sorry that was a bit of a garbled post...

The general consensus between the cd version, my teacher, and the folks on here is that most if not all should be appogiaturas, so I'll play around when I am confident on the notes but probably go with that. I think it sounds better anyway, certainly in most places in it.
