Ok, So I've always been big on practicing, usually packing in about 2 or 3 hours a day at least even with school. 3 out of my 4 orchestras ended and the last one doesn't have too difficult music, I mean its a little difficult at times depending on the tempo but not too bad. But now my teacher wants me to play the Dragonetti piece, but that's not the problem. He wants me to only do that for my practicing and give it my 100%. Now I can get by without practicing the orchestra stuff too much, just looking over it, but for some reason this concept of 100% on one piece is really hard to keep concentrated and keep that 2-3 hours. I know someones going to say "It's not about how long you practice.. yada yada yada" but is it good practice to simply work 100% on a movement? No exercises or etudes or scales (I still do these but he says they are all in the piece) my big problem is that practicing isn't as fun when I'm playing the same 40 measures which take about 2 minutes when played right, and I'm done practicing in a half hour, but I force myself to keep going. I often find myself looking at the clock more too. any comments?
