Note: This song is NOT "Bella's Lullaby."
I imagine this could easily be played on a piano as well; I only made a bare few changes to the original, such as the extra 16th notes in the left hand. It's a bit repetitive, but fairly relaxing. Any performers should feel free to improvise and add extra ornaments, chord patterns, etc. It's a good song for improvising, or just as background music.
(I really have to start playing some of these pieces again soon)
