It depends on what stage you're at. Most problems in the early stages are because you just haven't learned the notes yet. And that requires a certain (unknown) number of reps. It almost doesn't matter how you break a passage down, you're not going to learn it until you've done it enough times.
Is this for memorizing rather than reading?
That's interesting, I've been using that phrase "learning the notes", and now I'm not exactly sure what I mean by it. It's definitely not memorizing, because you still would have to look at the music, but only to remind yourself of what's coming next, or if there's some tricky fingering or something. Otherwise you can play the passage or the piece without having to stop to figure out what the notes are. Not yet at tempo, perhaps, but at least moving along. To me it's the key point in the learning process, when you can really begin to phrase etc. Am I the only one who breaks things down this way?
Slobone, it may be closer to memorizing than you think it is ! Just start taking the score away here and there, pretty soon you might play without it.
I'm not finding that to be true, there's a lot more involved in memorizing a whole piece than just being familiar with the notes. But yes, sometimes I do find myself looking down at my hands instead of the music for prety long stretches at a time.Learning the notes starts with sight reading, and progresses till you get to the point where you can play the piece without stopping, in some approximation of the correct tempo. At any given moment the sheet music reminds you of what notes are coming next. But you don't have to memorize the piece to get to that point.
