With 72/1, the only trills that really pose a problem are in measure 37. My version advises me to trill with the 3rd and 4th fingers, then when you do the chromatic run into measure 38, the fingering it shows is: 2 3 4 3 4 5 3 4 3 4 5. Personally I think that's a very strange fingering for the chromatic run. What do you guys think? How should I go about playing that measure?
