Whatever happened to the "Little Russian?"

Because Tchaikovsky used three Ukrainian folk songs to great effect in this symphony, it was nicknamed the "Little Russian" (Russian: Малороссийская, Malorossiyskaya) by Nikolay Kashkin, a friend of the composer as well as a well-known musical critic in Moscow. Ukraine was at that time frequently called "Little Russia". In April 2022, it was proposed by The Guardian that the sub-title "Little Russian" should be replaced with "Ukrainian" to clarify the musical inspiration for this work.
