In 1968, she premiered the song cycle Blasons anatomiques du corps féminin by Wilhelm Killmayer in Munich, with the composer as the pianist. In 1971, she was interviewed by Rudolf Lück for a book, along with eleven male musicians, about their interactions with composers who wrote music for them. The others included the conductor and composer Michael Gielen, the oboist Heinz Holliger, and the pianists Aloys and Alfons Kontarsky. Her chapter was titled "Von der 'Königin der Nacht' zur 'Lulu')" (From the Queen of the Night to Lulu). She mentioned her vocal range of three octaves, and the flexibility demanded by composers not only for fast changes in pitch and tone colour, but also for sound other tone production such as whispering, talking and yelling.
