However, we live in an age where many people are posting quality recordings for free online. A quick Google search can usually lead to a plethora of high quality pieces.
… For instance, in the season of Advent the chant is the Alma Redemptoris Mater. The others include Ave Regina Caelorum (Lent), Regina Caeli (Easter), and the Salve Regina (Ordinary Time). Over the years, my children have been picking up each of these (and the Ave Maria as well). This past Advent we added the last of the collection (Alma Redemptoris Mater), and nothing touched my heart more than when three of my children greeted me at the door about a week later excited to tell me that they had “learned it.” There they stood in front of the fireplace mantel, and they chanted in unison the most angelic melody I have ever heard.
