St Matthew Passion in the context of "Bach"

Johann Sebastian Bach (31 March [O.S. 21 March] 1685 – 28 July 1750) was a German composer and musician of the late Baroque period. He is known for his prolific output across a variety of instruments and forms, including the orchestral Brandenburg Concertos; solo instrumental works such as the cello suites and sonatas and partitas for solo violin; keyboard works such as the Goldberg Variations and The Well-Tempered Clavier; organ works such as the Schübler Chorales and the Toccata and Fugue in D minor; and choral works such as the St Matthew Passion and the Mass in B minor. Since the 19th-century Bach Revival, he has been widely regarded as one of the greatest composers in the history of Western music.

The Bach family had already produced several composers when Johann Sebastian was born as the last child of a city musician, Johann Ambrosius, in Eisenach. After being orphaned at age 10, he lived for five years with his eldest brother, Johann Christoph, then continued his musical education in Lüneburg. In 1703 he returned to Thuringia, working as a musician for Protestant churches in Arnstadt and Mühlhausen. Around that time he also visited for longer periods the courts in Weimar, where he expanded his organ repertory, and the reformed court at Köthen, where he was mostly engaged with chamber music. By 1723 he was hired as Thomaskantor (cantor with related duties at St Thomas School) in Leipzig. There he composed music for the principal Lutheran churches of the city and Leipzig University's student ensemble, Collegium Musicum. In 1726 he began publishing his organ and other keyboard music. In Leipzig, as had happened during some of his earlier positions, he had difficult relations with his employer. This situation was somewhat remedied when his sovereign, Augustus III of Poland, granted him the title of court composer of the Elector of Saxony in 1736. In the last decades of his life, Bach reworked and extended many of his earlier compositions. He died due to complications following eye surgery in 1750 at the age of 65. Four of his twenty children, Wilhelm Friedemann, Carl Philipp Emanuel, Johann Christoph Friedrich, and Johann Christian, became composers.

A chorale is the name of several related musical forms originating in the music genre of the Lutheran chorale:

• Hymn tune of a Lutheran hymn (e.g. the melody of "Wachet auf, ruft uns die Stimme"), or a tune in a similar format (e.g. one of the themes in the Finale of Saint-Saëns's Third Symphony)
• Such tune with a harmonic accompaniment (e.g. chorale monody, chorales included in Schemellis Gesangbuch)
• Such a tune presented in a homophonic or homorhythmic harmonisation, usually four-part harmony (e.g. Bach's four-part chorales, or the chorale included in the second movement of Mahler's Fifth Symphony)
• A more complex setting of a hymn-like tune (e.g. chorale fantasia form in Bach's Schübler Chorales, or a combination of compositional techniques in César Franck's Three Chorales [fr])

The chorale originated when Martin Luther translated sacred songs into the vernacular language (German), contrary to the established practice of church music near the end of the first quarter of the 16th century. The first hymnals according to Luther's new method were published in 1524. Luther and his followers not only wrote metrical hymn lyrics, but also composed metrical musical settings for these texts. This music was partially based on established melodies of church hymns and known secular songs. In the 17th century the repertoire was enriched with more choral and organ settings of the chorale tunes. By the end of the century a four-part setting for SATB voices had become the standard for the choral settings, while the congregational singing of chorales was tending towards monody with an instrumental accompaniment. The prolific creation of new Lutheran chorale tunes ended around that time.

In the 18th century, the appreciation of Johann Sebastian Bach's music was mostly limited to distinguished connoisseurs. The 19th century started with publication of the first biography of the composer and ended with the completion of the publication of all of Bach's known works by the Bach Gesellschaft. The "Bach Revival" started with Felix Mendelssohn's performance of the St Matthew Passion in 1829. Soon after that performance, Bach started to become regarded as one of the greatest composers of all time, if not the greatest, a reputation he has retained ever since. A new extensive Bach biography was published in the second half of the 19th century.

In the 20th century, Bach's music was widely performed and recorded, while the Neue Bachgesellschaft, among others, published research on the composer. Modern adaptations of Bach's music contributed greatly to his popularisation in the second half of the 20th century. Among these were the Swingle Singers' versions of Bach pieces (for instance, the Air from Orchestral Suite No. 3, or the Wachet auf... chorale prelude) and Wendy Carlos' 1968 Switched-On Bach, which used the Moog electronic synthesiser.

The Passio secundum Joannem or St John Passion (German: Johannes-Passion), BWV 245, is a Passion or oratorio by Johann Sebastian Bach, the earliest of the surviving Passions by Bach. It was written during his first year as director of church music in Leipzig and was first performed on 7 April 1724, at Good Friday Vespers at the St. Nicholas Church.

The structure of the work falls in two halves, intended to flank a sermon. The anonymous libretto draws on existing works (notably by Barthold Heinrich Brockes) and is compiled from recitatives and choruses narrating the Passion of Christ as told in the Gospel of John, ariosos and arias reflecting on the action, and chorales using hymn tunes and texts familiar to a congregation of Bach's contemporaries. Compared with the St Matthew Passion, the St John Passion has been described as more extravagant, with an expressive immediacy, at times more unbridled and less "finished".
