Secondly, how do you play this left hand passage without the hand tiring? The big jump between notes is pretty hard. I use 5-3-1-3 fingering in the lefthand here.
Lastly I have this passage learned in terms of hitting the right notes, but how do you achieve the mezza voce that is required in this passage? Is it for the left hand, the right hand or both?Also which passage in this piece is considered the most difficult?
I am currently learning this beautiful piece. Also which passage in this piece is considered the most difficult?
You might also try 5-4-1-4-1-4, with a "leap" from the 5 to 4. I find that the wider 4-1 span is worth the trouble of making the 5-4 jump, and it is less tiring on the hand. A rotation motion in the hand or wrist is definitely needed though; don't make your fingers do all that work alone. If you're having trouble with the jump, practice by playing the lower note, pausing and getting your left hand positioned up an octave, and then continue. Eventually this should become natural enough that you won't need to pause.As for the trills, not sure how fast you're playing this part, but just practice slowly and it should come.
