1 The first movement, "" ("Awake", we are called by the voice [of the watchmen]), is a chorale fantasia based on the first verse of the chorale, a common feature of Bach's earlier chorale cantatas. The cantus firmus is sung by the soprano. The orchestra plays independent material mainly based on two motifs: a dotted rhythm and an ascending scale "with syncopated accent shifts". The lower voices add in unusually free polyphonic music images such as the frequent calls "wach auf!" (wake up!) and "wo, wo?" (where, where?), and long melismas in a fugato on "Halleluja". John Eliot Gardiner, who conducted the Bach Cantata Pilgrimage in 2000, notes two instrumental choirs, the strings and the double-reeds (two oboes, taille and bassoon), playing in the style of a French overture double-dotted motifs in triple rhythm. He writes: 2 "" (He comes), is a recitative for tenor as a narrator who calls the "Töchter Zions" (daughters of Zion). 3 In the following duet, "" (When are You coming, my Salvation?), with obbligato violino piccolo, the soprano represents the Soul and the bass is the vox Christi (voice of Jesus). In a slow siciliano, the violino piccolo illustrates "the flickering of lamps 'lit with burning oil in arabesques. Gardiner comments: "A rich tradition of similarly sensual musical allegories, including fine examples by Bach's own cousin, Johann Christoph, stands behind this ravishing number." 4 The fourth movement, "" (Zion hears the watchmen singing), is based on the second verse of the chorale. It is written in the style of a chorale prelude, with the phrases of the chorale, sung as a cantus firmus by the tenors (or by the tenor soloist), entering intermittently against a famously lyrical melody played in unison by the violins (without the violino piccolo) and the viola, accompanied by the basso continuo. Bach later transcribed this movement for organ (BWV 645), and it was subsequently published along with five other transcriptions Bach made of his cantata movements as the Schübler Chorales. 5 The fifth movement, "" (Then come in to me), is a recitative for bass, accompanied by the strings. It pictures the unity of the bridegroom and the "chosen bride". 6 The sixth movement, "" (My Friend is mine!), is another duet for soprano and bass with obbligato oboe. This duet, like the third movement, is a love duet between the soprano Soul and the bass Jesus. Gardiner notes
