(c. 1660, burned 1774) where Bach composed and performed church cantatas monthly from 1714 to 1717 in 1885, one of the two
Leipzig churches where Bach composed and performed church cantatas almost weekly from 1723 to 1726
Vocal Typically Bach employs
soprano,
alto,
tenor and
bass soloists and a four-part choir, also
SATB. He sometimes assigns the voice parts to the dramatic situation, for example soprano for innocence or alto for motherly feelings. The bass is often the
vox Christi, the voice of Jesus, when Jesus is quoted directly, as in , or indirectly, as in . In the absence of clear documentary evidence, there are different options as to how many singers to deploy per part in choral sections. This is reflected in the recordings discussed below.
Ton Koopman, for example, is a conductor who has
recorded a complete set of the cantatas and who favours a choir with four singers per part. On the other hand, some modern performances and recordings use
one voice per part.
Joshua Rifkin is well known is an advocate of this approach, although it has yet to be followed through in a complete set of cantatas. Nonetheless, Bach would have had more singers available at
Leipzig, for example, while the space in the
court chapel in Weimar was limited. One size of choir probably does not fit all the cantatas.
Instrumental The
orchestra that Bach used is based on string instruments (
violin,
viola) and
basso continuo, typically played by
cello,
violone (at the same octave) and
organ. A
continuo bass is the rule in Baroque music; its absence is noteworthy and often has a special reason, such as describing fragility. The specific character of a cantata or a single movement is rather defined by wind instruments, such as
oboe,
oboe da caccia,
oboe d'amore,
flauto traverso,
recorder,
trumpet,
horn,
trombone, and
timpani. In movements with winds, a
bassoon usually joins the continuo group. Festive occasions call for richer instrumentation. Some instruments also carry symbolic meaning, such as a trumpet, the royal instrument of the
Baroque, for divine majesty and three trumpets for the
Trinity. In an aria of BWV 172, addressing the
Heiligste Dreifaltigkeit (Most holy Trinity), the bass is accompanied only by three trumpets and timpani. In many arias Bach uses
obbligato instruments, which accompany the singer as an equal partner. These instrumental parts are frequently set in virtuoso repetitive patterns called
figuration. Instruments include, in addition to the ones mentioned,
organ,
flauto piccolo (
sopranino recorder),
violino piccolo,
viola d'amore,
violoncello piccolo (a smaller cello),
tromba da tirarsi (slide trumpet) and
corno da tirarsi. In his early compositions Bach also used instruments that had become old-fashioned, such as
viola da gamba. Alto recorders (flauti dolci) are sometimes used in connection with death and mourning as in .
Solo cantata Some cantatas are composed for a solo singer (
Solokantate), as , for soprano, sometimes concluded by a chorale, as in , for bass.
Dialogue cantata Some cantatas are structured as a dialogue, mostly for Jesus and the Soul (bass and soprano), set like miniature operas. Bach titled them for example , concerto in dialogue. An early example is (1714). He composed four such works in his third annual cycle, (1725), , (both 1726), and (1727). == Text of Bach's sacred cantatas ==
