Today we commemorate Johann Walter, Kantor. Having begun his service — as a composer and bass singer — in the court of Frederick the Wise at the age of twenty-one, Johann Walter would go on to publish a collection of hymns that would become the basis of many subsequent hymnals. Walter would serve for a total of thirty years as kantor in the cities of Torgau and Dresden. Additionally, he aided Martin Luther in the preparation of the German Mass.
