⢠Bachâs music rental operation (p. 412):
Newly found documents about mailing costs for sending music to Bachâs second-generation pupil Johann Wilhelm Koch, cantor in Ronneburg (Thuringia) in the years 1732â44, provide evidenceâwith indications like âseveral cantatas sent back to Mr. Bachââfor the regular renting out of Bachâs cantatas, among them exacting works such as âHerr Gott, dich loben wir,â BWV 16; âSchwingt freudig euch empor,â BWV 36; and âIn allen meinen Taten,â BWV 97. Since we are not concerned here with just a single case, we can assume that St. Thomasâs cantor Bach was in a way functioning as a country church music director, taking care, to a certain extent, of his wider surroundings. Therefore he carried on his music business not only in Leipzig but also in the entire region. He could hardly have limited his distribution to his own works because his challenging compositions prevented anything like the thoroughgoing distribution enjoyed a generation later by the motets and cantatas of Bachâs pupil and cantor at the Holy Cross Church in Dresden, Gottfried August Homilius.

⢠The Art of Fugue and B-Minor Mass (p. 431â42):
The chapter-like systematic organization of The Art of Fugue is substantiated by Gregory Butler. Peter Wollny proves that Bachâs second youngest son, Johann Christoph Friedrich, assisted his father in the late 1740s (he copied, for example, the âFantasia chromaticaâ with its authentic titleâthe previously unknown source of BWV 903 was acquired in 2009 by the Leipzig Bach Archive) and that his hand shows up in additions and corrections of the autograph score of the B-Minor Mass, his fatherâs last vocal work. Michael Maul considers the possibility that Bach prepared his Mass for a performance on St. Ceciliaâs Day at St. Stephenâs Cathedral in Vienna on commission by Adam Count Questenberg. My own book on the Mass discusses the work in the context of an increased number of performances of Latin church music in Leipzig during the last two decades of Bachâs life.

⢠On Bachâs last months and final illness (pp. 448ff.):
The last known written musical entries by the composer occur, as Peter Wollny has shown, in the original performing parts of C. P. E. Bachâs Magnificat Wq 215, which was presented in Leipzig on either February 2 or March 25, 1750. The nature of the entries indicates his participation in the careful preparation of the performance, whether or not it took place under his own direction. Archival documents uncovered by Andreas Glöckner attest that Bach, despite the two eye operations he underwent at the end of March and the beginning of April, apparently remained officially in charge of church performances until the
