Ein feste Burg is one of the best known of Martin Luther’s hymns. The words, a paraphrase of Psalm 46, and melody were written sometime between 1527 and 1529. It is strongly associated with the Reformation. The original melody was much more rhythmic, but it has been standardized into the isometric rhythm shown above.
