Bach's Preludes. From painting by E. J. C. Hamman.

Heinrich Bach (1615-1692) was organist of the Franciscan Church at Arnstadt for fifty years, composed much, and had six children, three of whom were, in their day, noted musicians. Of the twin brothers, Johann Ambrosius and Johann Christoph, born in 1645, the first was town organist of Eisenach, and the second court musician at Arnstadt. These brothers were remarkably alike, not only in looks, but in character and temperament. They both played the violin in exactly the same way, they spoke alike, and it is said that their own wives could scarcely tell them apart. They suffered from the same illnesses, and died within a few months of one another. Johann Christoph once figured in an action for breach of promise of marriage brought before the Consistory at Arnstadt by Anna Cunigunda Wiener, with whom he had once "kept company." The court decided that Bach must marry her, but, with the independence of his family, he refused to do so, and he kept his word.

Another Johann Christoph, uncle of the great Sebastian, was organist at Eisenach for sixty years, and is, together with his brother Michael, distinguished as a composer. Maria Barbara, the youngest daughter of Michael, became Sebastian Bach's first wife. One Johann Jacob Bach was an oboe-player in the Swedish guard, and followed Charles XII. to his defeat at Pultowa, later becoming court-musician at Stockholm.

A vigorous, ambitious, and altogether remarkable family was this of the Bachs, and one of the most notable things about it is the uniformly high moral character of its members. Only one, of all those who flourished before Sebastian, is spoken of as being given to drink.

Wilhelm Friedemann, the oldest son of the greatest Bach, unfortunately had the same failing, and died in Berlin in 1789, poor and miserable through intemperance. His musical talent was exceptional, authorities calling him the greatest organist in Germany after his father. He is sometimes spoken of as the "Halle Bach," from having been music director of a church there.

The "father of modern piano music" was also the father of a large family, not less than twenty children having been born to him. The most celebrated of his twelve sons was Carl Philipp Emanuel, who is called the "Berlin Bach," having lived there in the court service for nearly thirty years. Emanuel was a prolific composer in all styles, and occupies an important place in the history of music. Another son, Johann Christoph Friedrich, was a composer and also chamber musician to Count von Lippe at Bückeburg, from which circumstance he is called the "Bückeburger Bach." Sebastian's youngest boy, Johann Christian (the Bach family evidently never wearied of the name of Johann), called the "Milanese" and afterward the "English" Bach, composed a large number of works,—songs, operas, oratorios, what not. He lived and worked at one time in Milan, where he was organist of the cathedral, and from there went to London, where he died in 1782. The daughters of Sebastian Bach—there were only eight of them—mostly died young, nor did they exhibit any special musical talent, and, after his sons' careers were ended, no one bearing the name has, we believe, won distinction in the art.

The Bach family were as a rule both sincerely pious and fond of innocent pleasure. Their tribal feeling was strong, and it was a custom to meet together once a year at Erfurt, Eisenach, or Arnstadt, and spend a day in friendly intercourse, exchanging news and relating experiences. Of course on these occasions they devoted some of the happy hours to music, and a favourite pastime was the singing of "quodlibets"—a kind of musical medley—wherein portions of several well-known songs would be dovetailed together.
