Lullaby

I need this song transposed so I can play on a double ocarina. My husband rescued the dog in the video who was with a foster family in Korea when the video was taken. I have no idea what the song is and it isn't played in full but would love to have as much of it as possible in tabs so I can play it for him when he arrives in the states next month. He seems to like it very much.

Thank you!
