Chopin - Right hand leads... ?

[drooxy]

Hi everyone !

I am still polishing the Nocturne Opus 9 N°2 (yes, I just love it !) and to do so, I listen to different interpretations of it. I listen more specifically (or more often) to the Rubinstein's version which, I believe, can be taken as a fairly good example ! 

Now, I have quite recently realized (better late than never  !) that the left hand has not to be regular, especially during the rubato... I would tend to think that the right hand actually leads the music. One should let it sing freely, and the left hand will follow.

Is that a good perception ?

Thank you !

The left hand should be strictly in time. Chopin ordered it himself, saying "The left hand is the clock. It's rhythm should be strict and unbroken."

Use rubato on the left hand, but do not change the pulse of the left hand.
