One who studies the German chorals as they appear in the hymn-books of the present day (many of which hold honored places in English and American hymnals) must not suppose that he is acquainted with the religious tunes of the Reformation in their pristine form. As they are now sung in the German churches they have been greatly modified in harmony and rhythm, and even in many instances in melody also. The only scale and harmonic system then in vogue was the Gregorian. In respect to rhythm also, the alterations have been equally striking. The present choral is usually written in notes of equal length, one note to a syllable. The metre is in most cases double, rarely triple. This manner of writing gives the choral a singularly grave, solid and stately character, encouraging likewise a performance that is often dull and monotonous. There was far more variety and life in the primitive choral, the movement was more flexible, and the frequent groups of notes to a single syllable imparted a buoyancy and warmth that are unknown to the rigid modern form. The transformation of the choral into its present shape was completed in the eighteenth century, a result, some say, of the relaxation of spiritual energy in the period of rationalism. A party has been formed among German churchmen and musicians which labors for the restoration of the primitive rhythmic choral. Certain congregations have adopted the reform, but there is as yet no sign that it will ultimately prevail. In spite of the mischievous influence ascribed to Luther’s hymns by his opponents, they could appreciate their value as aids to devotion, and in return for Luther’s compliment to their hymns they occasionally borrowed some of his. Strange as it may seem, even “Ein’ feste Burg” was one of these. Neither were the Catholics slow to imitate the Protestants in providing, songs for the people, and as in the old strifes of Arians and orthodox in the East, so Catholics and Lutherans strove to sing each other down. The Catholics also translated Latin hymns into German, and transformed secular folk-songs into edifying religious rhymes. The first German Catholic song—book was published in 1537 by Michael Vehe, a preaching monk of Halle. This book contained fifty-two hymns, four of which were alterations of hymns by Luther. It is a rather notable fact that throughout the sixteenth century eminent musicians of both confessions contributed to the musical services of their opponents. Protestants composed masses and motets for the Catholic churches, and Catholics arranged choral melodies for the Protestants. This friendly interchange of good offices was heartily encouraged by Luther. Next to Johann Walther, his most cherished musical friend and helper was Ludwig Senfl, a devout Catholic. This era of relative peace and good-will, of which this musical sympathy was a beautiful token, did not long endure. The Catholic Counter-Reformation cut sharply whatever there might have
