Johann Sebastian Bach composed the church cantataEin ungefärbt Gemüte (An open mind) (literally: An undyed mind), BWV24 in Leipzig for the fourth Sunday after Trinity and first performed it on 20 June 1723. It is the third new cantata of his first cantata cycle in Leipzig. The title has been translated more freely, for example as "An unstained mind", "An unblemished conscience",[1] "An undisguised intention", and "An unsophisticated mind".
The prescribed readings for the Sunday were from the Epistle to the Romans, "For the earnest expectation of the creature waiteth for the manifestation of the sons of God" (Romans 8:18–23), and from the Sermon on the Mount in the Gospel of Luke: the admonition to "be merciful" and "judge not" (Luke 6:36–42). It seems likely that Bach had not found yet a poet in Leipzig. He used a cantata text by Erdmann Neumeister, published already in 1714 in the collection Geistliche Poesie mit untermischten Biblischen Sprüchen und Choralen (Spiritual poetry with inserted biblical quotations and chorales).[5] In a composition of symmetry, Neumeister placed in the centre a quotation from the Sermon on the Mount in the Gospel of Matthew, "Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets." (Matthew 7:12). He framed it by two recitatives, and those by two arias.[4] The topic of the first recitative is "Die Redlichkeit ist eine von den Gottesgaben" (Sincerity is one of God's gifts).[1] In opposition, the topic of the second is "Die Heuchelei ist eine Brut, die Belial gehecket." (Hypocrisy is a beast coughed up by Belial).[1] The poetry on "Der Christen Tun und Handel" (The Christians' deeds and behaviour), stressing "Treu und Güte" (truth and goodness), has been criticised as "too didactic".[3] Gillies Whittaker described it as "dry, didactic statements and crude denunciations of the failings of mankind".[6] The cantata is closed by the first stanza of Johann Heermann's hymn "O Gott, du frommer Gott" (1630).[7]
In his composition, Bach stresses the weight of the central biblical quotation by giving it to the choir, and by scoring the framing recitatives and arias with reduced accompaniment.[4] The obbligato part in the first aria is played by the violins and viola in unison and resembles the vocal part.[2] According to John Eliot Gardiner, Bach thus evokes an "unstained mind".[6] Julian Mincham notes the "sombre and shaded tone quality" of the unison strings.[8] The following recitative, termed an "exemplary mini-sermon in its own right",[6] is secco and ends in an arioso. Here as in the first work for the same occasion, BWV 185, Bach shows the mirror effect of the words, "Mach aus dir selbst ein solches Bild, wie du den Nächsten haben willt!" (Make yourself into such an image, as you would have your neighbour be!)[1] by imitation of voice and continuo.[2] This phrase is rendered three times.[8]
The central choral movement, "a powerful chorus which forms the core of the cantata",[3] is in two sections: the complete text is once rendered in a free form, then again as a fugue,[2] comparable to the concept prelude and fugue.[4] Two oboes double the strings, a clarino plays an independent part. The prelude is in three symmetric sections. The fugue, a double fugue marked "vivace allegro", begins with the first vocal entrance only accompanied by the continuo, the first vocal entries are sung by the concertisten, the choir joins later.[6] The music reaches a climax when the clarino plays the theme as a fifth part to the four vocal parts. The movement ends in free sequences.[2] Mincham describes the "ceaseless activity through constant musical movement" of the music, the "fragmented rhythm" of the countersubject and the "breathless urgency" of the coda.[8]
The following recitative is similar to the first in structure, but accompanied by the strings adding emphasis, mostly on strong beats. The final arioso, without the strings,[8] stresses the prayer "Der liebe Gott behüte mich dafür!" (May dear God spare me from it!).[1][6] The last aria is accompanied by two oboi d'amore; they play a long "doleful" introduction that is repeated as a postlude. The voice picks up their beginning motif. The tenor voice sings an unusual coloratura line when the text ends on "Macht uns Gott und Engeln gleich" (makes us like God and the angels),[1] possibly representing the multitude of the Heavenly host.[8]
The eight lines of the closing chorale[9] in homophonic four-part vocal setting are richly framed by orchestral interludes and accompanied by the instruments. Bach found the style of chorale treatment in works by his predecessor in Leipzig, Johann Kuhnau.[3] The last prayer asks for "ein unverletzte Seel" (an unsullied soul) "und rein Gewissen" (and a clear conscience).[6]
