Sonata. An instrumental composition for one or two instruments, usually in several movements. The first sonatas written by Ukrainian composers were by Maksym Berezovsky (for violin and harpsichord) and Dmytro Bortniansky (for piano). Among Mykola Lysenko's many instrumental works there is a three-part piano sonata. At the beginning of the 20th century, Vasyl Barvinsky, Yakiv Stepovy, and Lev Revutsky wrote sonatas for piano; in later periods, Viktor Kosenko, Borys Liatoshynsky, Mykhailo Tits, Roman Simovych, Yurii Shchurovsky, and Myroslav Skoryk were some of the most notable Ukrainian composers to use the sonata form.
