What you really need to be doing, is playing the work through, from beginning to end, at a manageable enough tempo, that there ARE no 'difficult passages'. This way, there are never 'difficult passages' per say. There are only passages which contain certain difficulties.
What you really need to be doing, is playing the work through, from beginning to end, at a manageable enough tempo, that there ARE no 'difficult passages'... ...If you are trying to 'learn' a work, and you can't read it through from beginning to end on your very first practice session (not necessarily at full tempo, but certainly in one uninterrupted run at a slow-tempo) then it is highly likely that the work in question is of a complexity level that you are not yet prepared for.
...you may come up with a fingering for certain passages which works OK at a slow tempo but which is never going to work when you get up to speed. Just something to watch for......If you concentrate on just one difficult passage, then two things are likely to happen: first, it will spook you when you come to it later, particularly under pressure, and second it will be very difficult to get it properly integrated with the rest of the piece. I would never practice a difficult section alone; begin at the beginning of a phrase at the very least, and don't stop until you get at least to the end of the phrase beyond it -- if not the end of the piece.
I don't know what awesome will say -- but in my humble opinion yes, there is a definite hazard in playing or practicing something, particularly something near your level of ability, too slowly. That is that you may come up with a fingering for certain passages which works OK at a slow tempo but which is never going to work when you get up to speed. Just something to watch for...
Don't mean to hijack the thread, but can you elucidate this point awesom_o? In your opinion, is there a point where a slow-tempo is too slow? Or, provided you can keep an accurate(ish) rhythm can you go as slow as you like?
This has to be the biggest thing I am working on right now. I always seem to rush into music way too quickly because I want it to sound like it should at performance level, which, let's face it, is not going to happen unless I SLOW DOWN first!! I'm doing better with it than I have in the past but I definitely need to watch myself.
awesome_o, iansinclair and anyone else really: What are your thoughts on the "section practice" as espoused by Bernhard (and others) - whereby a piece is broken up into sections small enough to "master" in 20mins or less, then linked together, etc? In your opinions, could one become a highly competent musician following this path?
This can still be a big thing for well-established concert pianists! If you can overcome this weakness earlier rather than later, your musicianship will develop both hugely and rapidly!
