Seven famous singers tackling a very tricky aria. Uncomfortable high notes, long breath control required in the final phrase of the melody.
It is also difficult to manage the accompaniment, especially in the reprise. It is interesting how each one solves the problem of breath control in her own way, and how the syllabification of the text is often accommodated.
I am asking for enlightenment, especially from any singing experts present in the forum
