 The first of three arias, "Kreuz und Krone sind verbunden" (Cross and crown are bound together), reflects the conflicting motifs of "Kreuz und Krone" (cross and crown) and "Kampf und Kleinod" (conflict and jewel). The aria for alto voice and an oboe which almost always present, is in da capo form, ABA. A ritornello frames part A, but also accompanies the vocal entry. It is thus heard six times in different context, related to the repetitions of the passacaglia of movement 2. The music illustrates the union of the four contrasting elements (all beginning with K): Kampf is sung as a melisma with a trill in measure 15, the preciousness of the jewel appears as a trill in the voice or the accompaniment. The text is also repeated in the middle section, as Bach was still experimenting with the da capo form.
