the Symphonic Suite for grand orchestra. Suchoň became heavily involved in the practical and theoretical aspects of music education. Of particular significance was his second opera Kraľ Svätopluk ("King Svätopluk"), completed in 1959. This historic opera represents the monumental dramatic fresco from the period of the Great Moravian Empire. It is a large-scale work with noble aspirations, displaying Slavic motifs and culminating in the victory of good over evil. The work was premiered in Bratislava in 1960, and performed the same year in Prague and Košice. Later years From 1959 to 1974 he was professor of music theory at Bratislava University. His style changed as he incorporated serialism into his compositions. Harmonies emphasizing 2nds, 4ths and 7ths led to polymodality. His later output consists predominantly of chamber and orchestral works, e. g., the song cycle Ad astra (1961), based on poems by Štefan Žáry, the mixed choir cycle O človeku ("about a human"), the Poème macabre for violin and piano, Contemplations for narrator and piano, Six Compositions for Strings, the Rhapsodic Suite for piano and orchestra and the Symfonická fantasia na BACH (1971). His piano cycle Kaleidoscope also exists in a version for piano, string orchestra and percussion. His last works include a Concertino for Clarinet and Orchestra, Elegy, Toccata, and the song cycles Glimpse into the Unknown and Three Songs for Bass. Suchoň died in Bratislava in 1993.
