This posthumous compilation of writing by beloved scholar, teacher, and musician Mark P. Bangert explores how, in addition to his other contributions, Martin Luther expressed a theological valuation of music that can inspire and inform today's understanding and use of music, especially in Christian worship. Luther's preface to Symphoniae iucundae ("e;Delightful Symphonies,"e; 1538) presents the clearest explication of this theology. At the time of his death, Bangert had composed core components of a book on Luther's preface. Drawing on this work and other writings by Bangert on Luther and music, Martin Seltz has edited a collection that pays tribute both to Luther's theology and to Bangert's important body of scholarship.
