In the three
arias Bach sets extreme
affekts to music: desperate lament, intense longing and blissful joy. The first aria is based on an
ostinato continuo, comparable to the opening of . First the violin, then the tenor perform an expressive melody and repeat it several times. The contrasting middle section is underlined by tremolos in the strings in daring harmonies.
John Eliot Gardiner remarked in connection with his
Bach Cantata Pilgrimage, that on the words "" (O thunderous word in my ears), "it contains a graphic evocation of ear drumming". The second aria is accompanied by the two oboes d'amore and the violins and viola in unison, without continuo. Similar to the soprano aria in Bach's
St Matthew Passion, the lack of foundation portrays fragility and innocence. The joy of the finding is expressed in a duet of alto and tenor in
homophonic vocal lines of parallel thirds and sixths. It is in three parts, the third not a da capo of the first, but an affirmative conclusion in a faster
time. Movement 3 is a four-part setting of
Johann Schop's tune of "" (1642), which became famous as part of , and was also used in movement 40 of the
St. Matthew Passion. The closing chorale is a four-part setting of a 1658 tune by
Andreas Hammerschmidt. == Recordings ==
