The press admired him for his virtuosity, his temperament, and his analytic character; for the rhythmic finesse of his interpretations, as well as the powerful and explosive performance of his pieces.
He gained the foundations of his proficiency at the music school for talented children in Târgu Mure?, where he began to take lessons already at age six. Grauers fast artistic progress was soon recognized through performances for the Romanian television and early broadcast- and studio-recordings.
At the age of 14 he won the 1st prize on the national level of the Romanian competition Ciprian Porumbescu. Shortly after this, he emigrated to Germany and found a new home in Aachen. Proclaimed as a “wunderkind at the piano”, he became a junior student in the class of Prof. Pavel Gililov at the Hochschule für Musik und Tanz in Cologne.
Scholarships in the years 1986-1994 enabled him to participate in important, international master classes taught by, for example, Zoltán Kocsis, György Cziffra, Eliza Hansen, Christoph Eschenbach, Karl-Heinz Kämmerling and Rudolf Buchbinder, where he gained crucial impetus for his musical career.
Grauer's repertoire covers a diverse range of epochs of piano music. His focus, however, is on pieces by Beethoven, Bartók, Chopin, Liszt and Grieg. Formed by the master classes of Zoltán Kocsis and his own Hungarian heritage he passionately embraces the pieces by Bartók.
In addition to numerous projects such as chamber music and vocal accompaniment, Peter Grauer gave concerts in several European as well as Asian countries. His acquaintance with Justus Franz made it possible for him to give his own concert in 1994 at the Schleswig-Holstein-Musik Festival. In 1999, Grauer toured through Japan and delighted his listeners with ten concerts. He elated his sophisticated audience in Turkey in 2004, and received rapturous applause on his tour in America in 2009.
