Yes, it’s a real subject and yes, it’s a real class. Our assignment was to write a hymn tune to an existing text or widely used meter. I chose this text because I despise the music written by Rousseau in the LDS hymnal. Sadly, I only noticed later that my melody was all too similar to his.
Also, I had to harmonize it. I just couldn’t leave it alone. Seriously, how do you expect me to write a hymn tune without harmonizing it? If you like it, you can print it and use it freely. Just give credit, it is still copyrighted.
