To an extent quite without parallel in the history of music, the power of Luther's tunes, as well as of his words, is manifest after three centuries, over the masters of the art, as well as over the common people. Peculiarly is thistrue of the great song _Ein' feste Burg_, which Heine not vainly predicted would again be heard in Europe in like manner as of old. The composers of the sixteenth and seventeenth centuries practised their elaborate artifices upon it. The supreme genius of Sebastian Bach made it the subject of study.7 And in our own times it has been used with conspicuous effect in Mendelssohn's Reformation Symphony, in an overture by Raff, in the noble_Festouverture_ of Nicolai, and in Wagner's Kaisermarsch; and is introduced with recurring emphasis in Meyerbeer's masterpiece of The Huguenots. It is needless to say that the materials of this Birth- day Edition of Luther's Hymns and Tunes have been prepared in profusion by the diligence of German scholars. But very thankful acknowledgments are also due to English translators, who have made this work possible within the very scanty time allotted to it. Full credit is given in the table of contents for the help derived from these various translators. But the exigencies of this volume were peculiarly severe, inasmuch as the translation was to be printed over against the original, and also under the music. Not even Mr. Richard Massie's careful work would always bear this double test; so that I have found myself compelled, in most cases, to give up the attempt to follow any translation exactly; and in some instances have reluctantly attempted a wholly new version. The whole credit of the musical editorship belongs to my accomplished associate, Mr. Nathan H. Allen, without whose ready resource and earnest labor the work would have been impossible within the limits of time necessarily prescribed. In the choice of harmonies for these ancient tunes, he has wisely preferred, in general, the arrangements of the older masters. The critical musician will see, and will not complain, that the original modal structure of the melodies is sometimes affected by the harmonic treatment. And now the proper conclusion to this Introduction, which, like the rest of the volume, is in so slight a degree the work of the editor, is to add the successive prefaces from the pen of Luther which accompanied successive hymn-books published during his life-time and under his supervision.
