GreetingsWhile I agree with stevie and tac-tic's posts, I feel that there is much more to a piece of music than merely sightreading through it. Don't get me wrong, the ability that you have is envious and no doubt the result of alot of pratice from an early age. However, I feel that to do a piece justice, one has to 'internalize' it. That is to say that a piece needs to be studied and analized and yes, memorized to really give it life as the composer intended.One down side to not having any pieces memorized is if you are ever at a gathering that has a piano and are asked to play, without your music you're toast.
