This is NOT the official lullaby from Twilight. I listened to this song while I was reading the books BEFORE the movie came out (although I think it sounds nicer than the actual lullaby in the movie). The song in this video is River Flows In You by Yiruma. The title of the video is meant for the listener to imagine Edward playing it for Bella. However, the real artist and song name are STILL IN THE TITLE. Sorry for the confusion!
Regardless, this is a beautiful song and I hope you all recognize that! :) #stopthehate

Google "River Flows In You by Yiruma sheet music" and you can learn how to play!

Please BUY the song!

Thank you so much for so many views! This is crazy! 
And, because I've seen comments related to this, I am NOT playing this in the video. This piece was recorded by Yiruma!
