Cis-Dur
The chromatic structures are sometimes surprising, as in the beginning of "La mia doglia s'avanza", whose opening chords move from G minor to F-sharp major then D minor and finally C-sharp major, commencing a series of descending chromatic figures. In "L'amoroso veleno", the voices use small, chromatic ascending scales to mimic the poison which slowly creeps up to the victim's heart.
