After the war, Tyrmand resumed her musical education with remarkable determination. She completed her studies at the Belarusian State Conservatory, graduating in piano performance under Professor G. Shershevsky in 1949, and in composition under Professor A.V. Bogatyrev in 1952. This period marked the beginning of her significant contributions to Soviet musical culture.
Tyrmand's compositions reflect both her wartime experiences and her deep connection to Belarusian musical traditions. Her work "Elegiac Improvisation" for violin and piano, composed years after the war, serves as a poignant memorial to the Holocaust. The piece's structure, featuring extended cadenzas for both instruments, shows influences of Shostakovich's compositional style while maintaining its own distinctive voice.
Her catalog of works spans multiple genres, with particular emphasis on chamber and choral music. Notable compositions include:
- Two piano concertos (1952 and 1956)
- Multiple piano suites, including "Scenes from Children's Life" (1953)
- Numerous vocal cycles setting texts by poets such as Maksim Bahdanovič and Federico García Lorca
- Various works for traditional Belarusian folk instruments
For nearly four decades, Tyrmand served as a professor at the Belarusian State Conservatory, where she shaped several generations of musicians. Her teaching methodology emphasized the artistic interpretation of musical works, always striving to imbue performances with genuine human emotion. Among her notable students were Honored Artist of Belarus L. Tolkacheva, Professor A. Korzhenevskaya, and Associate Professor S. Okolova.
Tyrmand's compositional style is characterized by its intimacy, romantic expression, and subtle lyricism. Her work successfully merged traditional Belarusian musical elements with contemporary classical techniques, creating a unique voice in Soviet-era classical music. She showed particular skill in writing for children, creating numerous piano suites and choral works specifically for young performers.
Eta Tyrmand passed away on April 29, 2008, leaving behind a rich legacy of musical works that bridge her wartime experiences with her artistic vision. Her compositions continue to be performed and studied, serving as important documents of both musical development in Belarus and the resilience of artists who survived one of history's darkest periods. As a pioneer for women in classical music composition, her achievements continue to inspire new generations of composers, regardless of gender.
