'The Piano' is the work of Aidan Gibbons, made in his 2nd year of university at age 18. He originally used the music 'Comptine D'une Autre Ete' by Yann Tiersen, however when the DfES adopted the video to be used an educational resource, the copyright could not be obtained for the track. A wonderful piece of animation with a very moving soundtrack - there are two different versions, here's is the lesser-known one. I don't know the name of this music but it was written by Stephen Jones.
