Ich habe meine Zuversicht (I have [placed] my confidence), BWV 188, is a church cantata by Johann Sebastian Bach.
However, the score was "cut to pieces and sold to private individuals" in the 1800s; the work as it now exists is a reconstruction.
[4] The work is scored for four solo voices (soprano, alto, tenor, and bass), a four-part choir, two oboes, taille, two violins, viola, organ, and basso continuo.
It opens with a string ritornello doubled by oboe; the two parts move into counterpoint after the tenor enters.
The final movement is a four-part setting of the chorale tune, doubled by oboe, taille, and strings.
