Rivaling childbirth and Britney Spears music. I was doing some Dohnyani etudes, mostly the first few (which involve holding down the first three fingers while trilling slowly with 4 and 5, 3 and 5, and 4 and 3), and I have so much trouble with 4/5. I just can't keep the fingers even, can't keep the 5 bent, and it's a nightmare. Is there some magic pill that helps remedy my tremendous lapse in finger independence, or am I doing something wrong? I've stayed away from technik etudes for the most part, outside of a little Czerny, Hanon, and Dohnyani, should I use those to practice those difficult motions?
