Johann Sebastian Bach composed Vergnügte Ruh, beliebte Seelenlust (Delightful rest, beloved pleasure of the soul),[1]BWV170, a church cantata for the sixth Sunday after Trinity in Leipzig. It is a solo cantata for alto that he first performed on 28 July 1726.
The first aria is a da capo aria in a pastoral rhythm. The musicologist Julian Mincham notes: "The first stanza is enigmatically poetic and its essence is an evocation of that peace and inner contentment".[10] The Bach scholar Alfred Dürr describes the mood as contemplative, and the melody of the voice as expansive, on a background of repeated quavers in the instruments.[4]
The first recitative is secco, only accompanied by the continuo.[4]
The second aria is set without continuo, rare in Bach's compositions, and symbolic of the lack of direction in the lives of those who ignore the word of God, as spoken about in the text. The organ plays the upper parts, which the violins and viola in unison form the lowest part.[4]
The second recitative is accompanied by the strings and continuo. The strings play mostly long chords but illustrate the words "bei Gott zu leben, der selbst die Liebe heißt" (to live with God, whose name is love)[1] by more lively movement.[4][7]
The final aria is a triumphant song of turning away from the world and desiring heaven. The words "Mir ekelt" (I feel revulsion)[1] are expressed by an unusual tritone opening the melody. The voice is ornamented by figuration in the organ, which Bach set for flauto traverso for a performance in his last years.[2][11]
