Here at this site, I noted the following about the background music
The interpretation of the music that you will hear is composed based on the notes discovered on the Tilma of Our Lady of Guadalupe through the position of the stars in her mantle, which is the same position of the stars in the sky of the day of Her apparition to Juan Diego and the flowers of her robe.
Following is the music, Immaculate Harmony.
You can also play Immaculate Harmony at the website Katy sends:
