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) 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 harpsichord concertos, BWV 1052–1065, are concertos for harpsichord, strings and continuo by Johann Sebastian Bach.  There are seven complete concertos for a single harpsichord (BWV 1052–1058), three concertos for two harpsichords (BWV 1060–1062), two concertos for three harpsichords (BWV 1063 and 1064), and one concerto for four harpsichords (BWV 1065).  Two other concertos include solo harpsichord parts: the concerto BWV 1044, which has solo parts for harpsichord, violin and flute, and "Brandenburg Concerto" No. 5 in D major, with the same scoring.  In addition, there is a nine-bar concerto fragment for harpsichord (BWV 1059) which adds an oboe to the strings and continuo. Mein Gott, wie lang, ach lange?

He composed it in Leipzig for the occasion of "Ratswechsel ", the inauguration of a new town council in a church service, probably in 1742.  Parts of the cantata appeared in a wedding cantata (BWV 120a ) and a cantata (BWV 120b ) commemorating the Augsburg Confession in 1730.  Bach reworked the choral second movement for the "Symbolum Nicenum" of his Mass in B minor. Johann Sebastian Bach (31 March [O.S. 21 March] 1685 28 July 1750) was a German composer and musician of the Baroque period.  He is known for instrumental compositions such as the "Brandenburg Concertos" and the "Goldberg Variations", and vocal music such as the "St Matthew Passion" and the Mass in B minor.  Since the 19th-century Bach Revival he has been generally regarded as one of the greatest composers of all time.
