Passing his exams with distinction (Wüllner-Prize), he also won the Felix-Mendelssohn-Prize twice: as a pianist in 1913 and as a composer in 1918. After serving in the Austrian army during the war, he lived in Germany until 1923. There he devoted himself to the radical directions of the avant-garde (dadaism and jazz - he even composed a jazz-oratorio, HMS Royal Oaks and his most known work, the Hot Sonata) also being influenced by impressionism, expressionism and neo-classicism, one after the other or even in parallel.
As a gifted pianist, he specialised in jazz and in the quarter-tone repertoire of Alois Hába and his pupils. Returning to Prague in 1923, he was very successful as a composer as well as an internationally appreciated pianist (particularly in Germany). Nevertheless he wasn’t able to continue his career in Germany after 1933. The Berlin world premiere of his opera Flammen was cancelled due to the political changes folowing the beginning of the Nazi regime. In the thirties abandoning a lot of things appreciated before, such as in particular the field of symphonic jazz, he then turned to writing symphonies in the style of socialistic realism. This sharply contrasted to his work for the Prague Radio in Ostrava, where he - being banned from profession since 1939 - continued to work under pseudonym as a jazz pianist.
Having taken the soviet nationality in 1941 he applied for a visa to the Soviet Union in April. However, although the visa had been granted on 13 June, it was too late: Schulhoff, who due to Germany’s declaration of war to the Soviet Union had now become citizen of an enemy state, was interned in Prague on 23 June 1941 and deported into the Concentration Camp Wülzburg near Weißenburg/Bavaria, where he died on 18 August 1942. Schulhoff’s work includes an opera, ballets, six symphonies, numerous works of chamber music, solo works, concertos, songs and choral works.
