"Mario Del Monaco addressed [Milanov] respectfully on many occasions as 'Maestra di canta', especially as they came offstage together after singing the tomb scene of AIDA. During rehearsals for that scene and for the final scene of ERNANI, to name but two examples, he was observed frequently requesting her assistance in learning how to sing certain passages softly."
