One of the most important Czech coloratura sopranos of her generation, she has had an active international career at the world's major opera houses and concert stages for roughly four decades.
She made her professional opera debut in 1965 at the Liberec Theatre as Konstanze in Wolfgang Amadeus Mozart's The Abduction from the Seraglio.
Among the large number of roles she has performed with the house include Susanne in Le Nozze di Figaro, Fiordiligi in Cosi fan tutte, the Queen of the Night in The Magic Flute, Rosina in The Barber of Seville, Norina in Don Pasquale, Gilda in Rigoletto, Violetta in La Traviata, and Zerbinetta in Ariadne auf Naxos.
In 1977 she made her first appearance at the Salzburg Festival performing a solo concert of Mozart arias which was recorded on the Supraphon label.
She has notably recorded several song cycles by such 20th century Czech composers as Pavel Bořkovec, Jaroslav Ježek, Iša Krejčí, and Jan Seidel.
