From French Cooking to French Music

When I was choosing Christmas carols for my Finetune playlist, I was disappointed that I was not familiar enough with any French carols to be able to choose some. Happily, Nathaniel came home from his first college choir class with the music for Quelle est cette odeur agreable? (Whence is that goodly fragrance flowing?) He is singing bass and really likes the piece but is struggling with pronunciation. This is his first exposure to French.
