I know trills here supposed to start on upper, but it really feels like it shoulcn't.
And that first grace note, Is it on the beat?
For common purposes, "grace notes" in Mozart-era music are not "grace notes." Their are acturaiaiisturas (sorry) and they are played in time. They are "naughty notes" and therefore written smaller but played as though they run with the big boys.
Big thank you, very big. I'm still working on it. That was a great big help.
