This truly is a happy tune! I can just imagine what you described that the track shows the innocence of what the students should be experiencing at that time instead of dealing with all the darkness! I watched Harry Potter to a certain extent until they became too dark for me. I am intrigued by the software you used, Synthesia is it? I have been wondering how that is done. I am trying to learn to play piano, the easy way and I have seen tutorials similar to yours and I think it is so cool to have that to assist with learning. Thank you for sharing this track with us!
