Evangelist (Bach)

The Evangelist in the music of Johann Sebastian Bach is the tenor part in his oratorios and Passions who narrates the exact words of the Bible, translated by Martin Luther, in recitative secco. The part appears in the works St John Passion, St Matthew Passion, and the Christmas Oratorio, as well as the St Mark Passion and the Ascension Oratorio Lobet Gott in seinen Reichen, BWV 11. Some cantatas also contain recitatives of Bible quotations, assigned to the tenor voice.

Bach followed a tradition using the tenor for the narrator of a gospel. It exists (and is also often called the Evangelist) in earlier works setting biblical narration, for example by Heinrich Schütz (Weinachtshistorie, Matthäuspassion, Lukaspassion, Johannespassion).

In contrast, the vox Christi, voice of Christ, is always the bass in Bach's works, including several cantatas.

The Evangelist reports in secco recitatives accompanied by basso continuo only.

In the St John Passion the story consists of chapters 18 and 19 of John the Evangelist, the St Matthew Passion tells the complete chapters 26 and 27 of Matthew the Evangelist. The first versions of the St. John Passion contained two additional lines from Matthew mentioning the weeping of the disciple Peter and the tearing of the temple curtain. Bach composed the weeping in an expressive melisma and the tearing in a forceful downward run followed by tremolo, but removed the parts in later versions.
