Rach's Elegie- roll technique

[jbmajor]

About half way through this piece, there is a half note chord structure on the 3rd beat of the measure with a roll going from an Ab octave in the bass to a treble Gb chord that has a dotted quarter Bb above it, marked l.h. (left hand), and then an eighth note marked r.h. (right hand) immediately following. 

I am wondering, are all the half notes meant to be played l.h., or just the bass and the dotted quarter note?  I ask because it seems a stretch to get a good roll using just the left hand when you have to jump from the bass to the treble. 

If you are familiar with any of this, thanks for your suggestions.

        Well, this is a very interesting question that I had never thought about. I play the bass Ab and dotted quarter note with the left hand, and the inner chord and the eighth with the right hand. I believe this is not only part of technique, but also common in Rachmaninoff's music the emphasizing of graceful movements of the hands, here caused by the quick motion of the two hands and then the passage of right hand over the left while it pulls back from the Bb quarter note. I also believe this movement gives more confidence and better accuracy, and the emphasizing of the upper notes. This is certainly a brilliant piece. If I were you, I would choose the one you feel fits the best for you, freely, since there are no footnotes on the score about it (at least on my edition). I hope this was helpful, and also hope you find the best solution.

Wouldn't the left hand be going over the right (while it's playing the treble chord) to hit that Bb quarter note? 

[Barbosa-piano]

That is correct, I did't pass the right message on my reply! I meant that the left hand pulled back after playing the Bb note.
                                        I'm sorry! I should have written that a little more clear.
