Everything you've described is absolutely normal. The most important thing to keep in mind is to use efficient and effective motions of your entire playing apparatus. It's not just what finger you use, it's how the entire body must move to align it so that it's easy and effortless. If you find two ways to depress the keys and one is easier, pick the easier one. Later, if you find an even better way to depress the keys, learn it and forget the old way. If you do this, you'll find that you'll be learning and forgetting a lot as you progress. Never rely on inefficient movements even if you're used to them. They will be a hindrance in the long run.Playing both hands together, assuming that you can do separate flawlessly (ease, comfort, musical effectiveness, etc.) requires the coordination of both sides of the brain. This can take quite some time to learn to do but it's faster if you practice diligently.What are you researching?
Thanks, that's a relief. I started to get the scale (spent most of the time on C) down with both hands but I still have a long way to go. Interesting, I wasn't looking into different ways of hitting the keys, but I'll remember that. I watched some videos to observe playing a scale with the left and right hand to get started, but basically for the piano, there is no accepted method for playing? Whatever works best for the pianist?
As for research, I'm continuing a research project I've been a part of since freshman year of college (will be a junior in the fall) and we are studying Circadian Rhythm using drosophila fruit flies and how light exposure affects their sleep cycles. My role is mostly to breed and take care of the flies and also prepare the experiments, where we use about 320 flies and each has to be put to sleep and placed in tubes for light exposure. The experiments last 2-3 weeks, so I have a lot of free time otherwise and I'm also studying for the MCAT to take in August.
