Thanks for your replies !! Abell88:the problem is see in your proposed way to play the trill is that not all notes will be the same value.Bernhard:an image is better than thousands of words !!You confirmed what i tought I am currently playing the first version you showed.According to your opinion, and your knowledge of the piece, do you think that the second version will sound much better?
Thanks again !!i already have a Naxos CD with this sonatina. Szokolay (sp?) plays it wonderfully (insane speed in 3º movement ).
