it has a trill but I can't really get it beyond Adante speed. I was wondering, if you want to trill faster do you have to use different fingering? or is there a limited speed?
I study as a job, it's necessary that you are happy studying,excuse my english, I'm study now the Goldberg variations, I make a plain in a paper, I writte that I study every day, houres, minutes, my objectives, I make a little table near me and I play houres and houres,do you know the Neuhaus's book about the piano? He say at a pupil: Sir, you study as a person who make "spaghetti", you put the watter at the fire, but when it's start ebullition you stop the fire..Do you understand me?.If you want study so fast you do'nt have time..You can study with all the calm thinking about the notes, the positions, repeat that and it's all
.... Later you should try to play the trill independent from the note values of the other hand, you may even have a variable tempo for the trill while the left hand stays in tempo....
