Sunday after Trinity. Bach first performed the cantata on 29 July 1725. Music Structure and scoring Bach structured the cantata in six movements and scored it intimately, as he did for many of Franck's works. The singers consist of four vocal soloists (soprano (S), alto (A), tenor (T), and bass) (B) plus a four-part choir only in the chorale. The instrumental parts are for two oboes d'amore (Oa), two violins (Vl), viola (Va) and basso continuo (Bc). The title of the autograph score reads: "9 post Trinit. / Thue Rechnung! Donner Wort / a / 4 Voci / 2 Hautb. d'Amour / 2 Violini / Viola / e / Continuo / di / J.S.Bach". The duration is given as 17 minutes. In the following table of the movements, the scoring and keys and time signatures are taken from Alfred Dürr, using the symbol for common time (4/4). The instruments are shown separately for winds and strings, while the continuo, playing throughout, is not shown. Movements 1 The work opens with a bass aria, accompanied by the strings, "" (Settle account! Word of thunder). Christoph Wolff notes: 2 The recitative, "" (It is only an alien good) is the first movement with the full orchestra. The oboes first play long chords, but finally illustrate the text figuratively, speaking of toppling mountains and "the flash of His countenance". The musicologist Julian Mincham notes that Bach's recitative is "both melodic and dramatic throughout", showing his familiarity with "the best contemporary operatic styles". 3 A tenor aria with the oboes in unison develops "" (Capital and interest). Klaus Hofmann calls the movement dance-like. 4 A secco recitative for bass demands: "" (Nevertheless, terrified heart, live and do not despair!). 5 A duet of the upper voices, only accompanied by the continuo, reflects "" (Heart, rend the chains of Mammon). Hofmann notes the dotted rhythm of the dance Canarie to the often canonic imitation of the voices. The word "zerreiß" (tear asunder) is depicted by a rest afterwards. The fetters (Kette) are illustrated with "slurred coloraturas", the term "Sterbebett" (deathbed) appears in "darkening of the harmony." 6 The closing chorale, "" (Strengthen me with Your joyful Spirit), is a four-part setting.
