Grieg's Notturno trills question

[dorfmouse]

Should the trills start on the principal note or on the note above? I find it slightly easier to fit them in against the bass when starting on the note ....

I think in context it fits better to start on the note.  Isn't that generally the case in Romantic music?  In Baroque and Classic they often started on the upper for the harmonic dissonance, but I don't think that's so much the case with Romantic music.

Thank you; I thought that in post classical music they generally start on the note. But then I read somewhere that if the first note is a repeated note (as in this piece) then you should start on the upper note. ... However, now that I've practised it a bit both ways I do think that it sounds better starting on the note here.
