He composed the chorale cantata in Leipzig for the 24th Sunday after Trinity and first performed it on 19 November 1724. "Ach Gott, wie manches Herzeleid " (Oh God, how much heartache) is a German hymn in 18 stanzas attributed to Martin Moller (1587).  It is often catalogued as a paraphrase of the Latin "Jesu dulcis memoria", a medieval hymn attributed to Bernard of Clairvaux, but only a few lines refer directly to this song.  The hymn is sung to an anonymous tune of "Herr Jesu Christ, meins Lebens Licht", which first appeared in Wolflein Lochamer's "Lochamer-Liederbuch", printed in Nürnberg around 1455. The Becker Psalter is a German metrical psalter published in two collections in 1628 and 1640 by the Leipzig theologian Cornelius Becker.  This publication was without melodies and meant to be sung to other well-known Lutheran hymns.  Becker included in his Psalter earlier Lutheran paraphrases of psalms, such as "Aus tiefer Not schrei ich zu dir", "Ach Gott, vom Himmel sieh darein", "Erbarm dich mein", "Ein feste Burg ist unser Gott". Johann Sebastian Bach composed the church cantata Ach Gott, vom Himmel sieh darein (Oh God, look down from heaven), BWV 2 , in Leipzig for the second Sunday after Trinity and first performed on 18 June 1724.  It is the second cantata of his second annual chorale cantata cycle, and is based on Martin Luther's hymn "Ach Gott, vom Himmel sieh darein ", published in 1524 in the first Lutheran hymnal. Ach Gott, wie manches Herzeleid (Oh God, how much heartache), BWV 3 , is a church cantata by Johann Sebastian Bach.  He composed the chorale cantata in Leipzig for the Second Sunday after Epiphany and first performed it on 14 January 1725.  It is based on the hymn published by Martin Moller in 1587. A Baroque violin is a violin set up in the manner of the baroque period of music.  The term includes original instruments which have survived unmodified since the Baroque period, as well as later instruments adjusted to the baroque setup, and modern replicas.  Baroque violins have become relatively common in recent decades thanks to historically informed performance, with violinists returning to older models of instrument to achieve an authentic sound. "Nun komm, der Heiden Heiland " (original: "Nu kom der Heyden heyland ", English: "Now come, Saviour of the heathens") is a Lutheran chorale of 1524 with words written by Martin Luther, based on "Veni redemptor gentium " by Ambrose.  It was printed in the Erfurt "Enchiridion" of 1524.  The chorale was used as the prominent hymn for the first Sunday of Advent for centuries.  It was used widely in organ settings by Protestant baroque composers, most notably Johann Sebastian Bach: he set it as the opening chorale prelude BWV 599 of Orgelbüchlein; and three times—as BWV 659 (one of his best known organ compositions), BWV 660 and BWV 661—in his Great Eighteen Chorale Preludes.  Bach used the hymn in his chorale cantata "Nun komm, der Heiden Heiland", BWV 62 (1724) and in the opening chorale fantasia of his earlier cantata "Nun komm, der Heiden Heiland", BWV 61 , BWV 61 (1714).  Max Reger composed a chorale prelude as No. 29 of his 52 Chorale Preludes, Op. 67 in 1902.
