In the opening chorus the soprano and the horn present the liturgical melody of the Te Deum, whereas the lower voices move in vivid counterpoint, but also a fourth part of oboe I and violin I.[4] The following secco recitative ends on the words "O, sollte darum nicht ein neues Lied erklingen und wir in heißer Liebe singen?" (O, should not therefore a new song be taken up and that we sing in heated love?).[1][2] Consequently, the following movement begins attacca (without a break) with the voices' "Laßt uns jauchzen, laßt uns freuen" (Let us celebrate, let us rejoice).[1][4] This unusual movement combines elements of chorus and aria in a free da capo form.[4] The first section is dominated by the chorus, the middle section by the bass.[4] Musicologist Julian Mincham points out that it is "an unusual and imaginative combination of aria and chorus" and likens it to the interaction between a pastor and his flock.[5] A second secco recitative leads to a tender aria which was accompanied by an obbligato oboe da caccia in 1726. In a later performance, likely in 1734, this was replaced by a "violetta", which can be a viola or a descantviola da gamba, according to Johann Gottfried Walther. The cantata closes with a four-part chorale.[2][4][6]
