I was watching Kara's video the other day and I figured out that I really like this piece. So, can anyone tell me where I can get my paws on "River Flows Into You-Yiruma"? Of course, I mean legally, as in, I'll purchase it. If you all could find it and give me links to it, that'd be fantastic. Thanks all!

here is the piano music. Just play the top notes. That is what I did in the video.

And then this one is an easier version for flute in a lower key that you can play along with. I also posted me playing this one. It is fun to play and the lady that writes these out has a whole bunch of them on her youtube channel.

The name of the piece is river flow in you.

Okay. Thanks so much!

Wow. I just printed it. It sounds easier than what's written! haha. Oh well. Again, thank you so, so much. I've heard this before but I can't remember where, and it's been my favorite piece of music. :D

You're welcome. It is from the movie Twilight.
