Aquarium from The Canival of The Animals

Saint Saens  

This is the music for the 7th song from The Canival of The Animals, the Aquarium. This music has a very mysterious atmosphere, and it is said that among the OSTs of the movie Harry Potter, there is a music with this song as a motif. I thought about going to a difficult arrangement at all, but I don't think there is a need to do so, and it has become a reasonable difficulty.
