Ok, so I spend all this time for years and years, since I was 9, obsessing over obtaining good technique and a nice rounded curve to my fingers when in piano playing posture. Now my old teacher critcized one of my performances, saying that my fingers were TOO curved, and if I would loosen up and flatten my fingers I would be a more expressive player. Problem is, I've spent so long of my life obsessing over this "perfect curve" that I'm to the point where I feel like I have to do EVERYTHING with my fingers curved, or my technique will be ruined. If I lift a box, my fingers are either curled under, or curved; if I do anything, and you look at my hands, my fingers are curved. I realize that I'm being kind of foolish here, but I can't stand the sight of my fingers on the few occasions that I've had the courage to try to fully extend them--either from all the years of keeping them curved, or something else, now when i try to straighten them, the tips of my fingers just curve upwards while close to the base stays bent. And it's not comfortable either to try to straighten them anymore. I certainly don't think I play bad, but my old mentor's criticism of my performance of Liszt's 12th Rhapsody took me by surprise. Is it truely bad to have a more curved finger playing style? I'm at a loss for what to do next.
