So I remember this movie I watched when I was a kid. I remember there were two kids who went to some musical world and helped this woman out. I think it was some sort of fairy tale world and the woman’s name was Melody. At the end of the movie, once they accomplished their mission, Melody changed from being a plain-dressed woman into a princess type. I’m pretty sure they sang songs in the movie and it was a pretty low budget film. I don’t know if it was an educational film or not. I saw this when I was 5 or 6 (20 years ago) so it was probably a 1980s or early 1990s movie.
