Johann Walther
Johann Walther (1496-1570) was a German composer and music theorist who became one of the most important figures in Protestant church music during the Reformation. As Martin Luther's close collaborator, Walther helped establish the musical foundations of Lutheran worship by composing and arranging numerous chorales and motets. He is best known for his *Wittenberg Gesangbuch* (1524), one of the earliest Lutheran hymnals, which standardized congregational singing in German churches. Walther served as Kapellmeister at the court of Saxony and authored influential music treatises that shaped Renaissance polyphonic practice. His legacy profoundly influenced the development of German Protestant music and established traditions that would culminate in the works of J.S. Bach.
