_Chorales._ The word “chorale” (“choral” in German) refers to the hymn tunes of Lutheran Protestantism, though in common usage the term includes the words associated with the tunes. The melodies had much to do with the popularity of the songs. They came from various sources. Many of them were original compositions by Luther and others; some were borrowed from the hymn books of the Bohemian Brethren; a considerable number were adaptations of plainsongs used in the Catholic Church; still others were adopted from beloved folksongs. Luther was an eclectic in his choice of music. He used any tune from any source that suited his purpose. Many thousands of chorales came into existence in Germany during his time and the two centuries that followed. The hundreds still in use represent the best in church music today. They are characterized by a plain melody, a strong harmony, and a stately rhythm; all of which adapts them well for effective congregational singing. The chorales at first did not have the regular rhythms that they later took on. The steady progression of even notes, invariable in Bach’s day, had come only gradually into use. Some of the recent hymnbooks, in the interest of greater variety of rhythm, are returning to the original “rhythmic chorales.” Though _unison_ singing has been widely practiced and is advocated today by some good authorities in church music, Luther encouraged part singing. In his first Preface to the _Geystliches Gesangbücklin_, 1525, he wrote: These songs have been set in four parts, for no other reason than because I wished to provide our young people (who both will and ought to be instructed in music and other sciences) with something whereby they might rid themselves of amorous and carnal songs, and in their stead learn something wholesome, and so apply themselves to what is good with pleasure, as becometh the young. The period of the German chorales may be said to have begun with Luther, 1483-1546, and ended two centuries later with J. S. Bach, 1685-1750. Bach brought the chorale tunes to their highest perfection, using many of them in his larger choral works. He composed about 30 original chorale melodies, wrote reharmonizations for approximately 400, and composed many chorale preludes for the organ which are in wide use today. The German hymns and chorale tunes, used constantly in the home and school, as well as in the church, have been of great importance in our Mennonite worship in the past. They constitute the main body of material in all our German collections of hymns. In an effort to preserve and emphasize this rich heritage, there was incorporated into the _Hymnary_, a special section, Book III, made up exclusively of chorales. German Chorales in the Hymnary
