[black_keys]

Hi, and sorry for taking your time , can any one suggest a good fingering for these passages ?
cz I cant find any good way to play them 

here for left hand (starting with the 2nd mesure) :




and here for both (starting from the 2nd mesure also) :



and thank you

Could you name this piece or say something about the tempo of this piece? The fingerings I use for some things can depend on the tempo.

From the grace notes before the second measure I want to say this..

541 | 53212 - RH plays Db and C - 21235 | 5

I'm not at a piano to try though, and i really think I need to try to be sure with this. How fast is it?

Oh sorry ! I forgot to tell you this is variation 26 from Rzewski the people united will never be defeated the tempo is 168bps

i didnt really have time to go through it all, i'm kind of to and from the computer through out the day..  and i hate to make a poor suggestion without trying it at a piano.

when you say second piece to you mean the next bar or the second image you posted?

I mean the second image    , they are two from the same piece

I'm trying to work this out at a desk..  i think I'll have to leave it, i'm just about going blind trying to figure out if it'll work.. I'd hate to suggest something that will fail terribly..

I think going up in the second bar its going to have to be 51, 3, 1, 5, 2, 1..  in the double notes at the bottom you have to let go of the 5 as you move over to 3.

Going down I'm not so sure, need to try a few things to see how to do it without some fairly contorted wrist action.. might see if I can try it tonight.
