The description for this item just says solo pack but doesn't say what that means. I was looking for Bella's Lullaby in a harder version then all the others on here. This version is a little more advanced then the easy version. It also contains several orchestration songs from the Twilight film. They are: Who are they?; The lion fell in love with the lamb; Stuck here like mom; Phascination phase. I haven't really played any of the other ones, but a couple look interesting and I will probably try them out. But if you are looking for sheet music to some of the background orchestration in the Twilight film this is the pack you want.
