Hi everybody !
I just started working on Chopin's etude op. 25 #11, and I am wondering whether the sixteenth notes on the left hand could actually be synchronized with those played with the right hand (for example, at measure 5, the Am chord could be played together with the E on the right hand), or not?
I suppose it should be played 6 against 4, but since I am currently working on polyrhythms and I find them annoying to play (I know I shouldn't be saying that or tackling such pieces if I am still at war with polyrythms

but anyways), I was wondering whether it would be acceptable to play them together, given the actual speed of the piece... in the same time, it would be a shame to learn it incorrectly and try to fix it later, so I don't know what to do.
Thanks a lot!
