Natalia Kawałek has a fine soprano extension and harmonizes well with Orliński, besides which it sounds tighter. At the end of the duet Rodelinda/Bertarido from "Rodelinda" the voices circle around each other in ornaments.

Orliński is the dominant figure - by virtue of the rich quality of its countertenor, which is balanced in all registers, responds well in height and naturally develops power in depth; in addition there are incredibly long phrases, light-footed coloraturas, sometimes accompanied by an excited tremor.
