Relationship with The Five

In 1856, while Tchaikovsky was still at the School of Jurisprudence and Anton Rubinstein lobbied aristocrats to form the Russian Musical Society, critic Vladimir Stasov and an 18-year-old pianist, Mily Balakirev, met and agreed upon a nationalist agenda for Russian music, one that would take the operas of Mikhail Glinka as a model and incorporate elements from folk music, reject traditional Western practices and use non-Western harmonic devices such as the whole tone and octatonic scales. They saw Western-style conservatories as unnecessary and antipathetic to fostering native talent.

Balakirev, César Cui, Modest Mussorgsky, Nikolai Rimsky-Korsakov and Alexander Borodin became known as the moguchaya kuchka, translated into English as the "Mighty Handful" or "The Five". Rubinstein criticized their emphasis on amateur efforts in musical composition; Balakirev and later Mussorgsky attacked Rubinstein for his musical conservatism and his belief in professional music training. Tchaikovsky and his fellow conservatory students were caught in the middle.

While ambivalent about much of The Five's music, Tchaikovsky remained on friendly terms with most of its members. In 1869, he and Balakirev worked together on what became Tchaikovsky's first recognized masterpiece, the fantasy-overture Romeo and Juliet, a work which The Five wholeheartedly embraced. The group also welcomed his Second Symphony, later nicknamed the Little Russian. Despite their support, Tchaikovsky made considerable efforts to ensure his musical independence from the group as well as from the conservative faction at the Saint Petersburg Conservatory.
