Círculo Beliáyev
The Belyayev circle came to dominate musical life in St. Petersburg. Composers who desired patronage, publication or public performance of their works through Belyayev were compelled to write in a musical style accepted by Glazunov, Lyadov and Rimsky-Korsakov. There was also peer pressure to compose in this style, as well as a distrust of composers who did not do so. Several composers who believed in the philosophy of the Belyayev circle became professors and heads of music conservatories in Russia, which extended the influence of the group past the physical confines of St. Petersburg and timewise well into the 20th century.
