You should give great care to the fingering you use here. I used (from the begining of the upwards scale) 2 3 1 (232) 1 2 1 (232) 1 2 3 4 4. Also, try to accent the first beat in the LH it gives you some control of the rythm. Tell me if it works out.
So it seems you play the trill part as (F-G-F) instead of (F-G-F-E-F), right? I guess that is easier as you don't play as many notes. I just played the (F-G-F-E-F) trill as it was suggested in the sheet music that I have.
I play grace notes rather than trills. I have attached a recording - see what you think.Steve
Very nice playing. Does the grace note you mention go like this, with 2 notes instead of 3, e.g. (G-F) instead of (F-G-F)
