Post by Tom HensPost by John BriggsFollowing on from a discussion in the 'Mass in F' thread, can anyone tell
me exactly how many separate autograph Bach (family) performing parts
there were for the 1733 Dresden B Minor Mass (BWV 232(I))?
Nobody can tell you that, since we only know which parts have survived, not
how many possibly existed originally.
Post by John BriggsI think I mean the instrumental parts - I know there were just 5 vocal
parts (SSATB).

Post by John BriggsIs there just the one Bass part? Is it figured? Are there any duplicate
parts? Are there any 'solo' and 'tutti' markings?
The surviving original parts of the "Missa", a.k.a. BWV 232 I, as preserved
Vocal: S I-II, A, T, B (as you say, one part each).
Instrumental: Tromba I-III, Timpani, Corno da caccia (for No. 11 only),
Flauto traverso I-II, Oboe (also Oboe d'amore) I-II, Violino I-II (2 parts
each), Viola, Violoncello, Fagotto (2 parts, diverging for No. 11 only);
and one Basso Continuo part, figured. The BC part also shows indications of
being intended as the conductor's part ("Direktionsstimme").
According to BWV 2a, the only instrumental 'solo' marking is in No. 6
(Laudamus te), "Violino solo", but I don't know if that's based on the
parts or from the partition.
You're right to refer to them as "Bach (family) performing parts". They
were largely copied out by Anna Magdalena, Wilhelm Friedemann and Carl
Philipp Emanuel Bach.
Happy New Year.
There's no doubt that the 1733 Dresden parts were intended for a
performance: they're written out very clearly and carefully, and the organ
part is written for a tuning a tone lower then Leipzig organs (which would
match the organ at the Dresden Sophienkirche, where W.F. Bach was organist,
and which is a possible locale for a performance). Moreover, the organ part,
very helpfully and practically, has cues for vocal entries written into it.
But WERE they used for a performance? They're in excellent condition, but
bear some finger smudges, which is suggestive but inconclusive. They may
have been used for one or a two performances, or not at all. The
fingerprints may have come from later handling.
It's been suggested that at ca. 1748-49 Bach began work to extend the Mass
into a "Missa Tota" for a specific purpose -- possibly the dedication of the
new Hofkirche in Dresden, which took place in 1751. As it turned out, Hasse
wrote a mass for that occassion -- and its Credo is remarkably similar to
Bach's. Did Hasse know Bach's version? Had Bach sent (no longer extant)
parts for at least some of his continuation of the Mass to Dresden before
his death?
Remember, Bach, unlike us, didn't KNOW he was going to die in 1750. He wrote
music for actual performance right up to the end, and may well have had a
performance of the complete Mass in mind -- but death overtook him.
