Dear Milla,
well, there's hope. when i first printed out 'Who's To Say' back in May, i gave up on the song, b/c i though the rhythm was too tricky. but when i picked it back up 2 or 3 weeks ago, i tried it out again, and EUREKA! i finally learned how to play the song! 'cause lord knows, i've wanted tio for so long.
i didn't bother to ask for any advice for how to play the song, b/c learning how to play it was something i had to figure out on my own. i thought the notes were all wrong and out of place, but they weren't. so my advice to you is to either improvise if the notes are too tricky, [that's what i do and it works, and that's what an artist does; takes someone else's work and makes it their own] or just practice, practice, practice, and don't give up. persistence does wonders!
