i have been laying the flute for some time now,but i want to start playing the piano. Does anyone who plays the flute and the piano give me any hints?

I think that it would be best to get a lesson book for it and if you need help then try to get an instructor. If you are going to teach yourself then try to follow the book the best that you can. I never even made it through half of my first book because I started to go blind and then had my instructor started helping me learn by interaction between what the book was doing and what I was supposed to do.
