The sheet music offered here is for “Reindeer are Better Than People” from Frozen and composed or given lyrics by Kristen Anderson-Lopez and Robert Lopez. It is arranged for the violin. It was transcribed from what I recalled of the sung version in the movie.
If I remember correctly, Sven and Kristoff are happily being best friends during this number, so we might suppose that the mood should be “Cheerful” or “Merry” despite the title being a blanket statement and perhaps slightly judgmental.
I would consider this as being for “easy violin”. I do not remember whether I changed the key of the piece to make the song simpler, so this may not be the original key.
