The most important of all are Etudes! start to practice Chopin etude 1 or 2 op.25 in a long period ( 3-4 ) months, slow and thoughtful. then you'll feel how much your hand and fingers got powerful and smooth!
Try BerceuseMy teacher says its such a great piece to learn his ornament style. I read through it after about the 5th time really looking at all of the right hand. Listen to it, then read the right hand first and work it out. Then see how to fit it over left hand. Fairly simple, few steps. Good luck. I just learnt this, so if you have questions, please ask!
