The structure of the St John Passion (German: Johannes-Passion), BWV 245, a sacred oratorio by Johann Sebastian Bach first performed in Leipzig on Good Friday 1724, is "carefully designed with a great deal of musico-theological intent". Some main aspects of the structure are shown in tables below.
The original Latin title Passio secundum Joannem translates to "Passion according to John".
Bach's large choral composition in two parts on German text, written to be performed in a Lutheran service on Good Friday, is based on the Passion, as told in two chapters from the Gospel of John (John 18 and John 19) in the translation by Martin Luther, with two short interpolations from the Gospel of Matthew (in the earliest version, one is from the Gospel of Matthew and one from the Gospel of Mark). During the vespers service, the two parts of the work were performed before and after the sermon. Part I covers the events until Peter's denial of Jesus, Part II concludes with the burial of Jesus. The Bible text is reflected in contemporary poetry and in chorales that often end a "scene" of the narration, similar to the way a chorale ends most Bach cantatas. An anonymous poet supplied a few texts himself, quoted from other Passion texts and inserted various stanzas of chorales by nine hymn writers. Bach led the first performance on 7 April 1724 in Leipzig's Nikolaikirche. He repeated it several times between 1724 and 1749, experimenting with different movements and changing others, which resulted in four versions (with a fifth one not performed in Bach's lifetime, but representing the standard version). The Passion, close to Bach's heart, has an "immediate dramatic quality".
The gospel account by John narrates the story in five "scenes". The corresponding movement numbers are given from the Neue Bach-Ausgabe (NBA).
Arrest (1–5), Kidron Valley (John 18:1–11)
Denial (6–14), palace of the high priest Kaiphas (John 18:12–27)
Court hearing with Pontius Pilate (15–26) (John 18:28–40 and John 19:1–22)
Crucifixion and death (27–37), Golgotha (John 19:23–30)
Burial (38–40), burial site (John 19:31–42)
Some musicologists regard movement 24 as the conclusion of scene 3, the aria "Eilt, ihr angefocht'nen Seelen" which locates the action from the courthouse to Golgotha, the calvary. Others, including Alfred Dürr, regard the scene as ending with the last comment by Pilate.
Bach incorporated two short interpolations from the Gospel of Matthew (in Version I, one from Matthew and one from the Gospel of Mark), Matthew 26:75 after John 18:27, describing the weeping of Peter, and Matthew 27:51–52 after John 19:30, describing the tearing of the temple curtain (in Version I, this was replaced by Mark 15:38). The narrator is the Evangelist, a tenor. Jesus and all other male characters are sung by a bass (including Peter and Pilate) or tenor (servant); female characters (such as the Maid) are sung by a soprano, while the people who are often summarily called die Jüden (the Jews), the servants of the High Priest, and the soldiers are sung by a four-part chorus (SATB) in dramatic turba movements. The "immediate, dramatic quality" of the "kind of musical equivalent of the Passion Play" relies on the setting of the interaction between the historical persons (Jesus, Pilate, Peter, Maid, Servant) and the crowd ("soldiers, priests, and populace").
At eleven moments in the Passion, stanzas from Lutheran chorales reflect the narration. Possibly Bach had an influence on their selection. He set them all in common time for four parts, the instruments playing colla parte with the voices.
Five chorales conclude a scene (in movements 5, 14, 26, 37 and 40); while a chorale opens Part II (15). Five chorales comment within a scene (3, 11, 17, 22, 28), including the central movement (22). One chorale accompanies the bass soloist in an aria (32).
Most chorale texts were written in the 16th and 17th century, by authors of the Reformation such as Martin Luther, Martin Schalling and Michael Weiße, and by hymn writers including Paul Gerhardt and Johann Heermann. The central chorale is not part of a common hymn, its text being taken from a libretto by Christian Heinrich Postel.
The third source for the text is contemporary poetry that reflects the biblical narration. It was compiled by an unknown author, who partly used existing text: from the Brockes Passion (Der für die Sünde der Welt Gemarterte und Sterbende Jesus, aus den IV Evangelisten, Hamburg, 1712 and 1715) by Barthold Heinrich Brockes, he copied the text for movements 7, 19, 20, 24, 32, 34, 35 (partly) and 39; he found movement 13 in Christian Weise's Der Grünen Jugend Nothwendige Gedanken (Leipzig, 1675) and took from Postel's Johannes-Passion (c. 1700) movements 19 (partly), 22 and 30.
The work is scored for vocal soloists (soprano, alto, tenor and bass), a four-part choir SATB, and an orchestra of two flauto traverso (Ft) (except for Version I, since all evidence of Bach's use of traverse flutes point to the 2nd Cantata Cycle as when he first used them), two oboes (Ob), two oboes da caccia (Oc), two oboes d'amore (Oa), two violins, viola (Va), and basso continuo. Bach added some instruments which were already old-fashioned at the time in arias for special effects, such as the archlute (Version I and 1739–1749 revision only, replaced by organ and/or harpsichord), the viola d'amore and the viola da gamba (Vg). Bach did not differentiate the vox Christi (voice of Christ), singing the words of Jesus, from the other bass recitatives and arias, nor the evangelist from the tenor arias.
The work displays a thoughtful symmetry. In the center of the five parts is the court hearing which confronts Jesus, Pilate, and the people. In the middle of the hearing, a chorale (22) interrupts the argument, which is a discussion about freedom and captivity. It is surrounded by two choral movements, which not only both ask for the crucifixion of Jesus, but also use the same musical motifs, the second time intensified. Again, in a repetition of similar musical material, a preceding turba choir explains the law, while a corresponding movement reminds Pilate of the Emperor whose authority is challenged by someone calling himself a king. Preceding this, Jesus is greeted in mockery as a king, corresponding in motif to the later request that Pilate should change the inscription saying he is "the King of the Jews" to "He said: I am the King of the Jews".
Bach led the first performance on 7 April 1724 at the Nikolaikirche (St. Nicholas) as part of a Vesper service for Good Friday. Part I was performed before the sermon, Part II after the sermon. Bach performed a second version on Good Friday a year later, 30 March 1725. Other versions were performed between 1728 and 1732 (version 3), and in 1749 (version 4). A final, fifth version, revised between 1739 and 1749, was never performed in Bach's lifetime.
