Leafing through old hymnals and sheet music, one finds all kinds of little presents—asterisks and footnotes in the texts of the first hymnologists, who studied the oldest Protestant hymns. Luther’s heritage and that of his contemporaries was dusted off, clarified, and … transformed by Bach into beautiful chorale cantatas, which, even in our time, can help us understand the hymn. In this Advent calendar, you will find such a present every day, a star to light your way to Christmas.
