The second son, Carl Philipp Emanuel, was very successful in the University, which he left in 1738, and proved himself not only such a gifted musician but excellent scholar in the sciences, that the Crown Prince of Prussia, known in history as Frederick the Great, summoned him from Rheinsberg to take the place of pianist in his musical chapel. There we shall shortly see him.

The third son, Johann Gottfried Bernhard, born at Weimar in 1715, was such a skilful player and accomplished contrapuntist at the age of twenty that he was fitted to fill an organist’s position with credit. A position of this kind was offered him about this time, partly at the solicitation of his famous father. Mühlhausen, the city in which Bach himself, a quarter of a century before, had spent the golden days of his first youthful freedom and domestic happiness, in grateful remembrance of the famous father gave the not-yet-famous son the organist’s position, much to the former’s delight.

Not long after this, another occurrence gave Bach great satisfaction. The Elector of Saxony and King of Poland, Frederick Augustus III, who was so greatly interested in the musical tournament at Count Flemming’s palace, when Marchand, the Frenchman, evaded Bach’s challenge by flight, had not lost sight of the master. After hearing him play at a church concert in Dresden, he appointed him “composer to His Majesty the King of Poland and Elector of Saxony”—a distinction which at that time was much sought after because of its personal value and far-reaching influence.

The old saying, “A prophet is not without honor save in his own country,” was verified in Bach’s case. He was greatly annoyed and distressed by serious differences and often very disagreeable disputes with his superiors, and sometimes with the Rector, over the affairs of the Thomas School and Church. Those small souls could not understand, much less appreciate, the unequalled achievements of a musician like Bach. From their point of view he was simply the Cantor of St. Thomas’s, and they grumbled and found fault whenever his actions or regulations were not in accordance with their commonplace ideas. The continual vexation which this caused him, as well as the feeling that such conduct on the Rector’s part must eventually bring both himself and his work into disgrace, led him seriously to contemplate resigning his position in Leipsic and seeking a new home elsewhere. With this contingency in view, he turned his eyes to Dantsic, a music-loving city, and with all the more hopefulness because Erdmann, the old true friend of his boyhood, lived and held an important position there. Since their separation at Lüneburg, Bach had kept up an irregular but cordial correspondence with his friend, and had the satisfaction of knowing that he held him in affectionate remembrance, and sympathized warmly with him in his welfare as well as in his troubles. Bach stated his circumstances to him with the utmost frankness, and complained of his meagre salary and the restrictions placed upon him by his unappreciative superiors, which exposed him to continual annoyance, jealousy, and persecution. Erdmann, who held an imperial position at that time, was extremely cordial, and promised to use his powerful influence in carrying out his friend’s wishes, though he could not do anything right away in securing a situation for him. This was not necessary, for relief soon came from another source.

That same year the rectorate was vacant, and, greatly to Bach’s delight, the learned Professor Gesner,[41] who knew the value of his work, succeeded to the position. The change in his circumstances made the life of the greatly troubled and poorly paid Cantor much more endurable, both in Leipsic and in the school. To the close of his life he found consolation for all earthly trouble and insufficiency in those inexhaustible sources of lofty musical ideas which God had given him to develop to the highest point of which he was capable, and to hand down to posterity in unsurpassed form. His happy domestic life, the success of his children, and the fine progress of his scholars, who gradually became skilful musicians, also strengthened and encouraged him; while his intimate relations with the Thuringian members of the family, who often visited him, and admired and loved him, helped keep his heart young.

Thus the years passed,—years of continuous care and toil, of faithful work “for the honor of the Highest,” of many severe personal trials, but also of many kindnesses, which strengthened the heart of the master as he grew aged. His fame grew beyond Leipsic. The number of his majestic tone-creations greatly increased. He was without a rival as a profoundly learned composer and skilful organist and pianist. And yet with all his honor and fame he worked quietly, unpretentiously, and manfully in his little closet at home for the support of his large family, and with absolute sincerity devoted his work to the glory of the Highest.

The saddest burden of his last years was the growing misconduct of his favorite son, Wilhelm Friedemann. Even in his boyhood he had manifested abnormal tendencies toward eccentricity, and in the course of years it had made him more and more disliked. Beside this, still worse traits of character revealed themselves, such as imperious haughtiness and repulsing moroseness of disposition, persistent indulgence in extravagant and bizarre musical fancies, notwithstanding the warnings of his father and friends, and, finally, over-indulgence in drink. Owing to his insolence, he had to leave his position in Dresden. With much difficulty he secured the place of organist at St. Mary’s Church, in Halle; but even there, desirable as the position was, he made no effort to curb his extravagances and dissolute habits, so that his father had good grounds for solicitude as to his future. And yet he charmed everyone with his fanciful and brilliant playing, and the hope was generally expressed that his talent would ultimately reach as high a standard of development as that of his father.

The progress of the second son, however, rejoiced the heart of the much-enduring old master. After the Crown Prince Frederick succeeded to the throne made vacant by the death of his father, Philipp Emanuel was appointed royal chamber musician and court pianist at Potsdam and Berlin, and was at this time enjoying the personal and musical distinction he so well deserved. Everything that came from him—letters, compositions, musical tidings of every kind—brought joy to the old father at St. Thomas’s, and caused him to rejoice in the rising fame and good fortune of his manly son. A message which Emanuel sent at this time to his father made ample compensation for all the trials of the last few years, and filled the modest home at St. Thomas’s with unalloyed satisfaction and delight. Frederick II, King of Prussia, the admired of all the world, victor at Hohenfriedberg and Sohr,[42] expressed his sincere admiration of “Master Bach” and the wish to see him in Potsdam as soon as convenient.

Bach was deeply moved by the message. All thoughts of his troubles in Leipsic disappeared, all his anxieties and cares were forgotten, and with fresh strength and courage he faced the future. There was nothing higher, nothing more precious in his estimation than his personal recognition by the greatest prince of his time. The future had nothing in store for him that could shake his courage or lessen his creative energy.

And yet the modest musician delayed gratifying the wish of the King. It was only when Frederick repeated his request in a more emphatic manner and threatened, in pleasant banter, to send a squad of hussars to Leipsic and arrest him and fetch him across the boundaries, that the old Cantor started for Berlin. With him went Wilhelm Friedemann, “Son of sorrow.”
