Chopin & mordents

[librisgeek]

Should mordents in Chopin's music be played starting on the note above the note the mordent is placed over?  For example:  A mordent placed over a B-flat played as C,B-flat,C,B-flat ?  Or should it be played just B-flat,C,B-flat ?   
The version I have been listening to (Evgeny Kissin's Carnegie Hall performance) sounds like the latter to me.  Any advice?

Mordents are always started on the principal note (the one written), Chopin's TRILLS, on the other hand, vary. He usually started them on the auxiliary (upper note).

Hope that helps. Looks like Kissin is right.

For Chopin, mordents start on the main note and are usually played before the beat.  As for trills, history records Chopin performed them staring on the auxiliary most of the time but many modern interpretations start them on the main note.

Thanks very much.  I've just started learning some Chopin pieces (and getting back into piano in general).  I didn't have any experience with mordents.  So thank you.
