ok i am really confused! The scene in twilght where edward is playing on the 钢琴 下一个 to bella, is that bellas lullaby 或者 is the song the river flows 由 你 the lullaby?
yes. That lullaby playing in the scene where Edward is playing for Bella, that is the lullaby. It's official name is Bella's Lullaby 由 Carter Burwell.
River Flows in 你 由 Yiruma was a 粉丝 picked lullaby. That means, before all the 电影院 came out, everyone liked that and wanted the lullaby to resemble that song.
New Moon, there was a completely different style of score music, instrumental pieces. There was no lullaby in New Moon.
