But that's the thing. I've done the repeated note set and all that crap, and as Bernhard says, "I have it mastered and don't need to practice it again." Why the *** did it just break apart like that?
I hear ya.. Remember though, the stuff Bernhard talks about isn't some "magic pill" that if you do it, and do it correctly, you will forever have your passage mastered.. It's a very sound approach, one that (for me at least, and clearly for him and his students) is working quite well. But the nature of forums and all, it's not really meaningfull for him to try to outline these methods and include all of the exceptions.. I'm sure his students deal with these kinds of things, but of course he's not toing to outline every place where everything he has said has failed for any given student of his. He's outlined the overall approach to the level of detail that is meaningful in writing. Of course things will fall apart, and you'll have to put them back together.. You're human.. I'm sure these types of things happen with his students as well (though I can't be sure, I'm just assuming) but he's outlined the approach. There's a chunk of my piece where I play octaves in both hands, a repeating pattern, cascading down like 5 octaves very quickly.. I've done all the tricks and repeated chord group sets etc.. had it mastered.. played perfectly the next day, and just as you, had it fall completely apart.. So I did it again.. and it still falls apart.. I just have to keep at it.
Remember, these methods are best for quickly learning the notes, getting them in your fingers. Like jlh said, you still have to be relentless in practicing the performance etc..
just keep at it.. use "Bernards Method" for all the great efficiency it will give to you, but don't expect it to be a magic pill that will simply allow you to play perfectly every time.. It will speed up the process greatly, and that's the worth of it, but it still takes alot of work and you're only human so of course there will be false starts.. (unless there is yet still something I'm missing in his approach, but I don't think that's the case)
