Piano Forum

Hello again; I really enjoy this site.  I'm glad to know there is a community of extremely helpful pianists that can help each other with whatever problems they have.

This is one of the pieces my upcoming piano instructor at school (for the fall semester) wants me to learn over the next couple of months.  I've ran through it with both hands a couple of times and I have a couple of questions, one for each hand.

1. In measure 13, there is what appears to be a descending seventh chord in the right hand, repeating the main motif of the song but starting on an F.  I'm using the urtext edition of Chopin's preludes, but the fingering has me very confused.  It says to use 1 on the G, then 2 on the F, and then back to 1 for the B flat... but that is extremely awkward to play, and after watching many YouTube videos of people performing this, it doesn't seem like they use that fingering.  I have instead been practicing very diligently on using 1 on the F, 2 on the B flat and then 5 for the B flat an octave above.  Does that sound okay?  I try to watch people's hands perform the piece but either the camera is too far away or their hands move too fast during this part for me to see what exactly they're doing.

2.  In measure 2 on the left hand, there is a trill on beat 2 with two grace notes before.  The trill sign (again, urtext edition) seems to imply that the trill should end on beat 3, which has the same grace notes but no trill.  If I'm correct, the grace notes should be played on the beat, right?  This little bit is repeated several times throughout the piece, so I want to be sure I know how to correctly play beats 2 and 3, especially with the higher notes above the grace notes.

Basically, I want to know what an ideal fingering for the right hand in measure 13 is, and how to properly perform beats 2 and 3 in the left hand in measure 2.  Thank you!
