away, and was buried before he could return to Cöthen. This was a
severe blow to the whole family.

Four years afterward, Bach married again, Anna Magdalena Wülkens was
in every way suited for a musician's wife, and for her he composed
many of the delightful dances which we now so greatly enjoy. He also
wrote a number of books of studies for his wife and his sons, several
of whom later became good musicians and composers.

Perhaps no man ever led a more crowded life, though outwardly a quiet
one. He never had an idle moment. When not playing, composing or
teaching, he would be found engraving music on copper, since that work
was costly in those days. Or he would be manufacturing some kind of
musical instrument. At least two are known to be of his invention.

Bach began to realize that the Cöthen post, while it gave him plenty
of leisure for his work, did not give him the scope he needed for his
art. The Prince had lately married, and did not seem to care as much
for music as before.

The wider opportunity which Bach sought came when he was appointed
director of music in the churches of St. Thomas and St. Nicholas
in Leipsic, and Cantor of the Thomas-Schule there. With the Leipsic
period Bach entered the last stage of his career, for he retained this
post for the rest of his life. He labored unceasingly, in spite of
many obstacles and petty restrictions, to train the boys under his
care, and raise the standard of musical efficiency in the Schule, as
choirs of both churches were recruited from the scholars of the Thomas
School.
