The inner movements are alternating recitatives and arias for solo singers and mostly obbligato instruments. An unknown librettist paraphrased the three inner stanzas as two sets of recitatives and arias. The "Motezuma" libretto recitatives were spoken, and other Vivaldi arias sung between them. In this opera, Hajibeyov created arias, mass choral scenes, various ensembles, ballet numbers and recitatives. It consists of two recitatives, an aria, and a final recitative. Carus-Verlag published Hellmann's work with newly composed recitatives and arias by Johannes Koch in 1999. Wunderlich had completed recording his arias, but Werner Krenn was hired to record the recitatives. He composed all missing recitatives, turba choirs and one aria. The score involves choral pieces, speaking choir, recitatives and songs. RV 638 consists of two recitatives around a single aria. Psalmodic chants, which intone psalms, include both recitatives and free melodies. Broadly speaking, liturgical recitatives are used for texts intoned by deacons or priests. He set the new texts as dramatic recitatives and love-duets, similar to contemporary opera. With it he demonstrated a mastery of orchestral color, accompanied recitatives, and melodic line. Again spoken dialogue, here written by Parks, replaced the opera's sung recitatives.
