how to study 3-4-5 combinations?!

[Remon]

Heey everybody  !

While I've been practising for the last time, it became clear to me that the 4th and the 5th finger (especially my left hand) are too weak.
Performing a ncie trill with these fingers is so difficult!
The 4-5 is also a problem for me in the Revolutionary Etude by Chopin, in the in G# minor-part (the middle part in Forte).
And when I'm studying for example a Czerny Etude with many "scale-like passages" in both hands, the 3-4-5 problem again occurs  

Do you people have any suggestions about how to study these finger combinations, so that I can play as fast and as musically with them as with the other fingers?

I can certainly give you a good starting point.  Go to Hanon's Virtuoso Exercises Part II.  Exercise #27 is the trill for 4th and 5th fingers both hands.  #28 is the 3-4-5 combination for your other difficulty.
Good luck!

There are many advanced technical exercises out there.  I used to have the same dilema like you.  I personally used Pischna to build up my finger strength after Hanon.  Now, I remind you, be very careful when you are working on exercises.  They can be dangerous when practiced wrong.  Pischna is an advanced mechanical exercises and you will achieve strong fingers.  I don't recommend that you play everything in there.  Just the ones that you need.  Since you are working on Chopin etudes I'm assuming that your chops aren't bad.

Anyway, that is my personal recommendation.  But remember, you need patience and diligent practice.
