Among the women who have influenced music without actually creating it, none have had greater chances to use their power than the wives of the famous composers. Often they have been endowed with no inconsiderable musical genius themselves, but have sacrificed their claim to renown upon the altar of domestic duty. Sometimes, in rare instances, they have had the ability to perform the double task of caring for the household and continuing their own musical labours. Their story is an interesting one, and from the time of the great John Sebastian Bach, who stands as a model of domestic purity, down even to the present day, they have played a large part in shaping the musical destinies of the world. From the twelfth to the seventeenth century is a long gap, and music underwent many changes during this period. After the passing of the minstrel knights, popular music fades out of sight. That it had an existence, however, is amply proven. The Jongleurs must have continued long after their masters were stamped out, for their direct successors are with us to-day, and our hand-organ is the descendant of their fearful and wonderful organistrum. The entire school of English national music saw its palmiest days during this epoch. Even on the Continent, the great schools of contrapuntists delighted to show their skill by employing as their cantus firmus, or chief part, some well-known popular song, such as "L'Homme Arme," for example. In Germany, the mantle of the Minnesingers fell upon the guilds of musical amateurs in the growing commercial cities. Less poetic than their predecessors, these Mastersingers, as they named themselves, often took refuge in arbitrary rules and set metrical forms that made a poor substitute for real inspiration. That there was some genuine poetic feeling and humour among them is shown by the work of Hans Sachs, the greatest of their number. He wrote many poems and plays, of which the "Fassnachtspiele" were the most popular and the most mirth-provoking. Contrary to the version of his life given in Wagner's opera, he succeeded in making a second marriage late in life; and contrary to the general experience in such cases, the marriage was a happy one, for his young wife was exceedingly proud of her famous husband. But in the actual creative work of the Mastersingers woman played no part.
