She is known for roles such as Wagner's Brünnhilde, Isolde, Ortrud and Kundry, and for Elektra and the Dyer's Wife by Richard Strauss, which she performed at international stages.
She then received an audition from Wieland Wagner, who recommended her to Bernhard Klee, then Generalmusikdirektor at the Theater Lübeck, who made her a member of the ensemble.
In Italian, she added Abigaille in Verdi's Nabucco, Élisabetta in his Don Carlos, and the title role in Puccini's Tosca to her repertoire.
In 1973, she took over the Empress in Die Frau ohne Schatten by Richard Strauss at the Staatstheater Nürnberg, staged by Hans-Peter Lehmann and conducted by Hans Gierster, with Karl-Heinz Thiemann as the Emperor and Astrid Varnay as the Nurse.
[5] In April 1981, she stepped in as the Dyer's Wife in Die Frau ohne Schatten, reviewed as "outstanding in every respect" and "inspired audience and critics both in her performance and through the perfect leadership of her powerful voice".
[6] In June 1981 Vinzing sang Siegfried-Brünnhilde at the Staatstheater Hannover "with a luminous voice"; "she unfolded a tremendous power and also got a lot out of the part in acting".
In June 1988 she sang Brünnhilde in Die Walküre in a concert performance at the Kölner Philharmonie with the Gürzenich Orchestra Cologne (Marek Janowski conducting); she won praise for "the size and volume of her apparently effortlessly used splendid soprano".
[14] Between 1976 and 1991, Vinzing made guest appearances in over 30 performances at the Vienna State Opera, including Senta, Leonore in Fidelio, Elektra, Dyer's Wife, Kundry, Brünnhilde and Isolde.
In Marseille she sang in October 1992, "vocally fully satisfying the demands of her part", also for the last time the Dyer's Wife, whom she portrayed as an "energetic, strong-willed woman without hysteria".
[2] She sang excerpts from Die Walküre and Götterdämmerung, in which her long-time stage colleagues Donald McIntyre (Wotan) and Spas Wenkoff (Siegfried) were her partners.
Later in her career she reduced her repertoire to about ten to twelve core roles, mainly in Wagner and Strauss (among others Brünnhilde, Isolde, Ortrud, Kundry, Elektra, and the Dyer's Wife).
Between 1974 and 1987, Vinzing sang the role of Brünnhilde in more than ten different complete Ring cycles, among others in Wuppertal (1974), Hanover (February 1983; in Die Walküre and Siegfried), Karlsruhe (April 1985, June/July 1988 in Götterdämmerung), Düsseldorf, Hamburg, Berlin (March 1986 in the complete ring cycle, in Die Walküre with "great musical certainty and acting maturity"[18][19] in November 1986 again in Götterdämmerung; also in March 1989 and May 1990), Cologne (June/November 1988 and June 1989; in concert performances of the Ring under Marek Janowski), Vienna, Geneva, Seattle (June and August 1984), Barcelona (March 1985; as Siegfried-Brünnhilde), Buenos Aires, Paris (1977, February 1986), Munich (May/June 1987, January 1988 with "victorious top notes"[20]) and Orange (July 1988).
There exist only two official audio documents: in 1984, a live recording of a concert performance of Elektra was released, first on LP and later also on CD.
It was made in Paris with the Orchestre National de France, conducted by Christof Prick; her partners were Leonie Rysanek as Chrysothemis, Maureen Forrester as Klytämnestra and Bent Norup as Orest.
