Massenet's opera, Thais, is one of my favorites. Many of you, no matter how familiar you are with classical music, have most assuredly heard one of the opera's most famous pieces, "Meditation." Listen to a YouTube clip of Yo-Yo Ma performing this sublime piece of music. Thais is a heart-wrenching opera that tells the story of a monk determined to convert a beautiful Venusian priestess to Christianity, and in the process, he falls in love with her. Though, I'm sure you can guess the outcome, learn the synopsis of Massenet's opera, Thais.
