Ok, i don't want please any comment about "leave that piece" hahaha please
I was about to learn this myself, and saw a youtube video of a man playing it, and I was surprised at the beginning:
After the strong C hit, it comes a nice waterfall from high pitches to the lowest. This waterfall was played with two hands, but in the score appears in the "upper" score, the right hand's score.
I know it is easier if you play it with two hands (evidently), but is it impossible to play it with only the right hand as smoothly fast as with two hands?
Thats my question.
Thanks for reading and commenting

The video, in case there is someone that doesn't know the beginning:
4-5-6th seconds
