1. Does make any sense to practice the rigth hand ALONE slowly, lets's say at mm=70?. Suppose that I start with the 2 notes as a chord, like you say, then I start "splitting" the notes, then, I slow down. Is there lower limit for this kind of practice?
2. Does make any sense to practice hands TOGETHER slowly, very slowly?
3. When playing the notes of the right hand, either as a chord or breaking it by "wiggling", (a) must I depress the keys to bottom?, ALLthe way down? (b) How can I make it sound pp? (c) Should I use pulling or pushing fingers? (d) curled, semicurled or flat fingers (Sorry, I have so many questions...I'm really confused about this stuff... curled fingers, flat fingers, pushing, pulling,.. I've read a lot, I bougth some books but It's really difficult without a real example.
5. When I play the right hand as a chord, hands together.. the chord is in the place of the first note of the triplet, the second, should I play it like a 1/16 note? (perhaps, I'm a little confused in rythm matters)
6. Should I use the pedal for practicing the left hand alone? and hands together?
7. And a last one.. when I play fast it is difficult to me to focus on the expression; what should I do?
