Notes on the background and context of J.S. Bach’s St. Matthew Passion
The Forces
St. Matthew Passion is unique in Bach’s output in that it requires a double choir and a double orchestra.
Several of his motets, the “Osanna” from the b minor Mass, and a couple of cantatas specify a divided
choir, but no other work has multiple groups of instruments. As for the voices, it has been argued that
Bach wrote St. Matthew Passion for only nine singers: soprano, alto, tenor, bass in each group, and an
extra soprano in ripieno for the chorale in the rst movement and to reinforce the top line in the closing
movement of the rst part. While this is possible and has been demonstrated on a few recordings, it is
more likely that Bach’s intentions were for small choirs of both voices and instruments, which is how it
is usually done today. However, back in the rst half of the 20th century, when symphony orchestras and
choral societies performed Bach passions, they used enormous forces numbering in the hundreds. There
are portions of the piece where this can be very eective, but to keep such a large group together, some
of the tempi have to be much slower than we are used to now. Otto Klemperer’s recording from 1960, for
instance, takes nearly four hours where John Eliot Gardiner’s from 1988 takes a little over two-and-a-half
hours using fewer than half the people.
Ideally, there would be at least eight soloists, four from each choir. Originally the soloists would have
sung in the choir as well but now it is more typical for them to only sing the arias and other solo
portions.
The part of the Evangelist, who sings most of the Biblical text, is for tenor. He sings almost entirely in a
style of heightened speech-rhythm singing called secco recitative, accompanied by organ and a bass
instrument (usually ‘cello). The part of Jesus is for a bass or baritone, and he sings in a similar style but
accompanied by a “halo” of strings. There are individual solo parts for Peter, Judas, the High Priest,
Pontius Pilate, his wife, two false witnesses, two maids, and two priests or Pharisees. So that these are
not always the same voices, these parts are oen sung by members of the choir.
Each orchestra is made up of violins, viola, two utes, two oboes, and a continuo group consisting of
organ and bass instruments: ‘cello, bass, and bassoon. In addition, a Renaissance instrument called the
viola da gamba (literally “viola of the leg”) is used in a couple of movements. This instrument is similar
in size to the ‘cello, but it has seven strings and is fretted like a guitar. It probably would have been
played by one of the ‘cellists.
The Texts
There are three main sources of text for St. Matthew Passion. The rst is the Gospel according to
Matthew, specically chapters 26 and 27. Because Bach was employed by the Thomaskirche in Leipzig,
an important Lutheran church, this is in German in Martin Luther’s own translation. Bach’s personal
copy of the Luther Bible survives, complete with marginalia and a few modications to the text, but for
the most part it is faithful to what Luther translated himself. The Biblical text is sung by the Evangelist,
Jesus, the lesser characters stated above, and occasionally by the choirs when they represent the crowds,
which are referred to by the Latin turba in a musical context.
