fast passage---EXACTLY how to practice

[piani0player]

hi everyone
    :'(After spending a lot of time practising all this fast  passage in the Mozarts sonata ,Bachs prelude and fuge and the apperggios passage at the end of the Chopin etudes op25 no.1. i still struggle to play them up to speed evenly and equal in tone quality.could someone just tell me EXACTLY how they practice fast passage??
i think i still dont know how to practice fast passage.

     This is how i practice fast passage----play the passage with the m.m. at a comfortable tempo with different rhythm than gradually increase the speed and
keep using the m.m. until its up to speed,sometime i can play them well but the next day it all become uneven and can't play up to speed.what wrong?

     For the chopin etude op25 no.1 , i still can't play the last apperggios run up to m.m. =104 per beat . i can only play it at about m.m. = 60-70 per beat?how to practise them correctly?
 thanks for your help

Hello !

I'm not an advanced player so I really didn't encounter fast-tempo pieces yet... but maybe this will help, until someone answer to you (correctly)

Ok, this may be ancient history (I've jst been scanning...), but if anyone reads this, I'll say the same thing I've said about fast passages (especially arpeggios), pertaining to the Waldstein originally:  Basically, you want to take all your notes and put the met. slow, and then play each hand alone (if both are fast), very slow and pricise and VERY loud and accented.  This will give your fingers greater independence (I.E. Phillipe exercises) and will keep the lengths even.  Then, do the same exercise (it can be faster this time) with every note staccato (again, first both hands alone, if both are fast).  This will make every note sounds clear and strengthen your wrist and fingers.  Basically, then you just have to play it again and again, and bring the speed up gradually.  I hope I've been of some help...
