List of compositions by Borys Lyatoshynsky explained

This is an incomplete list of compositions by the Ukrainian composer Borys Lyatoshynsky.

Lyatoshynsky wrote a variety of works, including five symphonies, symphonic poems, and several shorter orchestral and vocal works, two operas, chamber music, and a number of works for solo piano. He wrote music with a modern European style and technique, skilfully combining it with Ukrainian folk music themes. His musical style later developed in a direction favoured by the Russian composer Dmitri Shostakovich, which caused significant problems with Soviet critics of the time, and as a result Lyatoshynsky was accused of formalism and the creation of degenerative art.[1]

Lyatoshynsky’s main works are his operas The Golden Ring and Shchors, the five symphonies, the Overture on Four Ukrainian Folk Themes (1926), the suites Taras Shevchenko (1952) and Romeo and Juliet (1955), the symphonic poem Grazhyna (1955), his "Slavic" concerto for piano and orchestra (1953), and the completion and orchestration of Reinhold Glière’s violin concerto (1956).[2] He composed film scores for such films as  (1931), Ivan (1932, with Yuliy Meitus), Taras Shevchenko (1951),  (1956, with Mykola Kolessa), and  (1959). Many of his compositions were rarely or never performed during his lifetime.
