Needless to say, this artistic triumph had a momentous effect, especially since it was anything but just one lucky victory. Konstanze Eickhorst was also awarded the first prize at the Geza Anda Competition in 1988 and obtained prizes at the Bach Competition in Toronto in 1984 and the Concours Reine Elisabeth in 1987.

These competition successes were founded not only on her flawless command of technique but also and above all on the "intensity of expression" that the German music critic Joachim Kaiser recognized as one of her principal performance traits.
These international successes laid the cornerstone of a career that has since taken Konstanze Eickhorst to almost all the major music performance centers. Her guest performances at the festivals in Lucerne, Montreux, Salzburg, Ravinia, and Berlin, concerts with orchestras of the rank of the Toronto Symphony, Bavarian Radio Symphony Orchestra, Royal Philharmonic Orchestra, and Tonhalle Orchestra of Zurich, and appearances together with conductors such as Sandor Vegh, Christoph Eschenbach, Ferdinand Leitner, Andrew Davis, and Peter Schneider leave no doubt about the sustaining power of these successes.

Konstanze Eickhorst began instruction in piano at the age of five and studied under Karl-Heinz Kammerling in Hanover and under Vlado Perlemuter in Paris. She became one of the youngest professors in the history of German institutions of higher learning when she was appointed to a professorship at her alma mater, the Hanover Academy of Music and Theater, in 1989, and taught there before moving on to a professorship at the Lubeck Academy of Music in 1998.

Concurrently with her concert engagements, Konstanze Eickhorst regularly accepts invitations to serve on juries at national and international competitions. She is also active as an instructor of various master classes.
