Yes it is. if you haven't got it down redo it till you do.
I'm sorry but I don't see how the OP is helping anyone. And I don't trust anyone who refers to piano pieces constantly as songs.
Go through your piece a few times to get the feel for it. OK you said where to begin sight reading? well start with a song that's kind of difficult but not to hard so that you can't even do it.;)like the song your doing now. just keep trying till you get and you'll eventually learn it. your going to find it hard some times but you got to battle it. hope that answers your questions.Rose-
It begins with the fact that she is referring to "sight reading", which is prima vista, and then talks about repeating it until you can play it, which is no longer sight reading. I'm not even sure that it is reading because it could be memorization by then.
I think there is a very real truth in the idea that good sightreading has a lot do with learned pieces. When proper associations are drawn between notation and actions, even playing learned pieces is very good for the skills. If bad sightreaders start thinking properly about pieces that are already learned, there is much to be gained. Bad readers fall into the habit of memorising and then taking the notation for granted. A huge part of sightreading is the ability to draw association between actions and the notation.
