Thomaskantor in the context of "St. Thomas School, Leipzig"

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.

Wie schön leuchtet der Morgenstern ('How beautifully the morning star shines'), BWV 1, is a church cantata for Annunciation by Johann Sebastian Bach. In 1725, when the cantata was composed, the feast of the Annunciation (25 March) coincided with Palm Sunday. Based on Philipp Nicolai's hymn "Wie schön leuchtet der Morgenstern" (1599), it is one of Bach's chorale cantatas. Bach composed it in his second year as Thomaskantor in Leipzig, where the Marian feast was the only occasion during Lent when music of this kind was permitted. The theme of the hymn suits both the Annunciation and Palm Sunday occasions, in a spirit of longing expectation of an arrival. As usual for Bach's chorale cantata cycle, the hymn was paraphrased by a contemporary poet who retained the hymn's first and last stanzas unchanged, but transformed the themes of the inner stanzas into a sequence of alternating recitatives and arias.

Wie schön leuchtet der Morgenstern is the last chorale cantata of Bach's second cantata cycle, possibly because the librettist who provided the paraphrases for the middle movements of these cantatas was no longer available. Bach scored the work for three vocal soloists, a four-part choir and a Baroque instrumental ensemble of two horns, two oboes da caccia, two solo violins, strings and continuo. The chorale melody of Nicolai's hymn appears in the opening and closing choral movements of the cantata. All instruments play in the opening festive chorale fantasia, in which the soprano sings the hymn tune, and the two solo concertante violins represent the morning star. An oboe da caccia accompanies the vocal soloist in the first aria. The strings, including the solo violins, return in the second aria. An independent horn part crowns the closing chorale.

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".

The St. Nicholas Church (German: Nikolaikirche) is one of the major churches of central Leipzig, Germany (in Leipzig's district Mitte). Construction started in Romanesque style in 1165, but in the 16th century, the church was turned into a Gothic hall church. Baroque elements like the tower were added in the 18th century.

In the 18th century, several works by Johann Sebastian Bach, who was as Thomaskantor the music director of Thomaskirche and Nikolaikirche from 1723 to 1750, premiered here. The Neoclassical interior dates to the late 18th century.
