Animisha For a very short time I had a teacher who demanded memorisation, so I did try it. For me, it adds absolutely nothing. The piece did not become a part of me. When recording the piece, there are already so many things to think about, and adding to that the stress that I would not remember correctly, did not do my performance any good. However, maybe I should have spent even more time on that piece... (which would make me progress even slower...)
I don't think you reached the stage where the piece became a part of you! First, it has to be completely solid. And then the memorization has to be completely solid. I think my friend means that you have to be able to lose yourself in the music, and having your eyes open and tracking the music doesn't let you do that. I have memorized one piece to that level only because it was above my ability and took over a year for me to learn, it's the only piece that has stuck since childhood (Tchaikovsky's June). There's maybe one other piece that has stuck (Beethoven's Rondo in C). I literally can't even remember a lot of what I've played before, it just sounds familiar.
pianoloverus throwing back stress into the equation plus the huge amount of extra time needed to memorize I don't think it's worth it except maybe for a small number of pieces.
Yes, agree.
