Nikolai Andreievich Rimsky-Korsakov (1844-1908). It was only after becoming a professor of music at the St. Petersburg Conservatory that Nikolai Rimsky-Korsakov realized it would behoove him to learn some music theory. Once his studies were finished, he pushed his newfound learning on the rest of the “Mighty Five” – even posthumously “editing” his friends’ works to bring them into accord with “the rules.” Rimsky-Korsakov is best-remembered for his own works, which include Scheherezade and Capriccio espaсol.
