Cross them
it's written on the notes
also, it's for the chord sake and for the chords later on
you will get used to it, trust me.
and later in the part with all the chord running from the top
be careful of the accent of the Left right hand
it's kinda 'jazzy',
RH: TA,ti,ti-TA,ti,ti....
LH: ti,TA,ti-ti,TA,ti
ANd i have heard so many times people bang the shxt out of this piece... it's so wrong...
The first part of those big notes, except the beginning few bars(which indicate ff) all of them have to be play very very quiety with 2 theme, the low part is the main theme, the high part sound like the echo of the main part....
Good luck learning this piece. any more problem you can PM me.
