Rimsky-Korsakov found those in the Belyayev circle to be "progressive ... attaching as it did great importance to technical perfection, but ... also broke new paths, though more securely, even if less speedily ..." Increased contact with Tchaikovsky In November 1887, Tchaikovsky arrived in Saint Petersburg in time to hear several of the Russian Symphony Concerts. One of them included the first complete performance of his First Symphony, subtitled Winter Daydreams, in its final version. Another concert featured the premiere of Rimsky-Korsakov's Third Symphony in its revised version. Rimsky-Korsakov and Tchaikovsky corresponded considerably before the visit and spent a lot of time together, along with Glazunov and Lyadov. Though Tchaikovsky had been a regular visitor to the Rimsky-Korsakov home since 1876, and had at one point offered to arrange Rimsky-Korsakov's appointment as director of the Moscow Conservatory, this was the beginning of closer relations between the two. Within a couple of years, Rimsky-Korsakov wrote, Tchaikovsky's visits became more frequent. During these visits and especially in public, Rimsky-Korsakov wore a mask of geniality. Privately, he found the situation emotionally complex, and confessed his fears to his friend, the Moscow critic Semyon Kruglikov. Memories persisted of the tension between Tchaikovsky and The Five over the differences in their musical philosophies—tension acute enough for Tchaikovsky's brother Modest to liken their relations at that time to "those between two friendly neighboring states ... cautiously prepared to meet on common ground, but jealously guarding their separate interests".

This personal jealousy was compounded by a professional one, as Tchaikovsky's music became increasingly popular among the composers of the Belyayev circle, and remained on the whole more famous than his own. Even so, when Tchaikovsky attended Rimsky-Korsakov's nameday party in May 1893, Rimsky-Korsakov asked Tchaikovsky personally if he would conduct four concerts of the Russian Musical Society in Saint Petersburg the following season. After hesitation, Tchaikovsky agreed. While his sudden death in late 1893 prevented him from fulfilling this commitment in its entirety, the list of works he had planned to conduct included Rimsky-Korsakov's Third Symphony. Increasing conservatism; second creative drought In March 1889, Angelo Neumann's traveling "Richard Wagner Theater" visited Saint Petersburg, giving four cycles of Der Ring des Nibelungen there under the direction of Karl Muck. The Five had ignored Wagner's music, but The Ring impressed Rimsky-Korsakov: he was astonished with Wagner's
