UK Piano Page Piano Forum

Thanks Colin,
I missed the "natural" modifier below the turn notation, which made it sound not right. Instead of hitting the books, I hit Google with "bar 21 pathetique" for instant satisfaction. Silver lining is having found a wonderful piano discussion forum.

Proof that anything can now be found on the internet. I also searched for the answer about the specific note sequence in the bar 21 turn of Pathetique Mov2.
Amazing, and Thank You!
