Well, you see, i started my preparatory studies in the conservatorie (for the career (made an audition and they accepted me(yay! xD!))), and i think i need to improve my work with my LH, i was wondering if Moszkowski op.92 could be useful? Because i'd really like to improve my speed, accuracy, and especially i don't want to have problems when doing trills, i think that's my weakest point, For example, when playing Bach Invention 4, the long trill with the LH, i feel there is no enough speed (no speed at all!), Could you give me advice of some books ( Exercises and Etudes) for the left hand? I don't know.. If there is some Czerny, or like i was saying Moszkowski op.92, anything, i would really appreciate it!
Thank You!
