Viktor Ullmann (1898 – 1944) was a Czech composer, pianist and music critic of Jewish origins, whose mentors included Schönberg and Zemlinsky. While interned by the Nazis in Theresienstadt he composed, among other works, his last piano sonata, which he dedicated to his own three children. Ullmann left remarks on how to orchestrate the sonata for a large orchestra. The aim of my version for strings is to capture the richness of the orchestral version while keeping the intimacy of the piano. In 1944 he and his family were sent to their death in Auschwitz.
