a central chorale. He scored the work for three vocal soloists (alto, tenor, bass), a four-part choir and a Baroque instrumental ensemble of corno da tirarsi (Ct, a slide horn that Bach scored for a short period), flauto traverso (Ft), two oboes d'amore (Oa), two violins (Vl), viola (Va), and basso continuo. In the following table of the movements, the scoring follows the Neue Bach-Ausgabe. The keys and time signatures are taken from Alfred Dürr, using the symbol for common time (4/4). The continuo, playing throughout, is not shown. Movements The opening chorus reflects the contrast of hope and resurrection versus simultaneous remembrance and doubt, which is present throughout the cantata. The chorus is structured in symmetry in seven sections, beginning with an instrumental sinfonia of all instruments, the horn introducing a theme representing remembrance in a melody which resembles the choral tune of "" which Bach would later use as a cantus firmus in the opening movement of his St Matthew Passion. Bach thus alludes to the idea that Jesus suffered innocently for the "sins of the world" before he rose again. In the second section, this melody is sung by the sopranos, while the lower voices stress the word "Halt" (hold) by several homophonic chords. In the third section, the sopranos repeat the melody in a fugue, while the altos simultaneously sing a countersubject that rises in fast movement for more than an octave, illustrating the resurrection. The fourth section is a reprise of the sinfonia with the voices added, then a variation of sections 2 to 4 follows as 5 to 7. The tenor aria (My Jesus is arisen) is accompanied by an obbligato oboe d'amore. The theme is presented in the opening by the strings and later picked up by the voice, illustrating the word "" by an upward run. The Easter hymn "" marks the center of the composition. In symmetry, it is framed by two alto recitatives, the second a reprise of the first. The idea of a solo singer alternating with a chorus is extended in the following movement, the bass aria with chorus (Peace be with you). A string introduction depicts in agitated forte passages in 4/4 time the attack of the enemies. John Eliot Gardiner describes it as "a dramatic scena in which the strings work up a storm to illustrate the raging of the soul's enemies". In sharp contrast the
