that each of the four sections could be used separately." On the other hand, the parts in the manuscript are numbered from 1 to 4, and Bach's usual closing formula (S.D.G = Soli Deo Gloria) is only found at the end of the Dona Nobis Pacem. Further, Butt writes, "What is most remarkable about the overall shape of the Mass in B Minor is that Bach managed to shape a coherent sequence of movements from diverse material." Butt and George Stauffer detail the ways in which Bach gave overall musical unity to the work. The first overall title given to the work was in the 1790 estate of the recently deceased C.P.E. Bach, who inherited the score. There, it is called "Die Grosse Catholische Messe" (the "Great Catholic Mass"). It is called that as well in the estate of his last heir in 1805, suggesting to Stauffer that "the epithet reflects an oral tradition within the Bach family". The first publication of the Kyrie and Gloria, in 1833 by the Swiss collector Hans Georg Nägeli with Simrock, refers to it as "Messe" Finally, Nageli and Simrock produced the first publication in 1845, calling it the "High Mass in B Minor" (Hohe Messe in h-moll). The adjective "high", Butt argues, was "strongly influenced by the monumental impact of Beethoven's Missa solemnis." It soon fell from common usage, but the prepositional phrase "in B Minor" survives, even though it is in some ways misleading: only five of the work's 27 movements are in B minor, while twelve, including the final ones of each of the four major sections, are in D major (the relative major of B minor). The opening Kyrie, however, is in B minor, with the Christe Eleison in D major, and the second Kyrie in F-sharp minor; as Butt points out, these tonalities outline a B minor chord. Orchestration The piece is orchestrated for two flutes, two oboes d'amore (doubling on oboes), two bassoons, one natural horn (in D), three natural trumpets (in D), timpani, violins I and II, violas and basso continuo (cellos, basses, bassoons, organ and harpsichord). A third oboe is required for the Sanctus. Performance history In Bach's lifetime Bach conducted the Sanctus, in its first version, at the 1724 Christmas service in Leipzig, and re-used it in Christmas services in the mid-1740s. Scholars differ on whether he ever performed the 1733 Missa. Arnold Schering (in
