I'm looking for a certain kind of soundtrack music.?

I am looking for stuff that is subdued and melodic like that of Bella's Lullaby in Twilight, or The Wind of Change by Accoustic Alchemy. Of course, it doesn't have to be a soundtrack, but that is usually where I hear this sort of music. It is usually primarily guitar or piano, often with some orchestration in the background. If there are paticular artists or movie soundtracks, I can look up songs from there. Best lists and suggestions gets the points. Thanks.
