[1][2] Her signature roles were the Queen of the Night in Mozart's Die Zauberflöte and Zerbinetta in Ariadne auf Naxos by Richard Strauss.

[1] After engagements at the Theater Basel and the Staatstheater am Gärtnerplatz in Munich she made her Salzburg Festival debut in 1960 as Rosina in Mozart's La finta semplice.

[1] She created the role of Scolatella in the revised version of Henze's König Hirsch in Kassel in 1963, and Autonoe in his Die Bassariden at the 1966 Salzburg Festival.

These recordings display an artist who had an uncanny sense of sophistication in terms of ornamentation and a fearless bravura approach to the most daring virtuoso pieces.

Besides her very successful stage career, she also achieved great popularity during the 1960s and 1970s when she appeared in many operetta films such as Die Zirkusprinzessin or Wiener Blut, and musical television shows.
