In mid- to late-19th-century Russia, Pyotr Ilyich Tchaikovsky and a group of composers known as The Five had differing opinions as to whether Russian classical music should be composed following Western or native practices. Tchaikovsky wanted to write professional compositions of such quality that they would stand up to Western scrutiny and thus transcend national barriers, yet remain distinctively Russian in melody, rhythm and other compositional characteristics. The Five, made up of composers Mily Balakirev, Alexander Borodin, César Cui, Modest Mussorgsky, and Nikolai Rimsky-Korsakov, sought to produce a specifically Russian kind of art music, rather than one that imitated older European music or relied on European-style conservatory training. While Tchaikovsky himself used folk songs in some of his works, for the most part he tried to follow Western practices of composition, especially in terms of tonality and tonal progression. Also, unlike Tchaikovsky, none of The Five were academically trained in composition; in fact, their leader, Balakirev, considered academicism a threat to musical imagination. Along with critic Vladimir Stasov, who supported The Five, Balakirev attacked relentlessly both the Saint Petersburg Conservatory, from which Tchaikovsky had graduated, and its founder Anton Rubinstein, orally and in print.
As Tchaikovsky had become Rubinstein's best-known student, he was initially considered by association as a natural target for attack, especially as fodder for Cui's printed critical reviews. This attitude changed slightly when Rubinstein left the Saint Petersburg musical scene in 1867. In 1869 Tchaikovsky entered into a working relationship with Balakirev; the result was Tchaikovsky's first recognized masterpiece, the fantasy-overture Romeo and Juliet, a work which The Five wholeheartedly embraced. When Tchaikovsky wrote a positive review of Rimsky-Korsakov's Fantasy on Serbian Themes he was welcomed into the circle, despite concerns about the academic nature of his musical background. The finale of his Second Symphony, nicknamed the Little Russian, was also received enthusiastically by the group on its first performance in 1872.
