I have difficulties in interpreting two peculiar notes in Mozart's K.331 Andante Grazioso. I hope you can help in improving my performance.
First question is about the D note evidenced with the arrow:
How should I play that? It seems part of the previous chord, but the score shows it detached, so I am not sure how to approach that.
Another, maybe easier, question is about the very last A of the score (before the variations), you can see that with an arrow.
It shows both up and down stems. Is there a particular way I should interpret it?
