and orientalism in Scheherazade, possibly his best known work.Maes, pp. 175–176. He proved a prolific composer but also a perpetually self-critical one. He revised every orchestral work up to and including his Third Symphony—some, like Antar and Sadko, more than once. These revisions range from minor changes of tempo, phrasing and instrumental detail to wholesale transposition and complete recomposition. Rimsky-Korsakov was open about the influences in his music, telling Vasily Yastrebtsev, "Study Liszt and Balakirev more closely, and you'll see that a great deal in me is not mine". He followed Balakirev in his use of the whole tone scale, treatment of folk songs and musical orientalism and Liszt for harmonic adventurousness. (The violin melody used to portray Scheherazade is very closely related to its counterpart in Balakirev's symphonic poem Tamara, while the Russian Easter Overtures follows the design and plan of Balakirev's Second Overture on Russian Themes.) Nevertheless, while he took Glinka and Liszt as his harmonic models, his use of whole tone and octatonic scales do demonstrate his originality. He developed both these compositional devices for the "fantastic" sections of his operas, which depicted magical or supernatural characters and events. Rimsky-Korsakov maintained an interest in harmonic experiments and continued exploring new idioms throughout his career. He tempered this interest with an abhorrence of excess and kept his tendency to experiment under constant control. The more radical his harmonies became, the more he attempted to control them with strict rules—applying his "musical conscience", as he called it. In this sense, he was both a progressive and a conservative composer. The whole tone and octatonic scales were both considered adventurous in the Western classical tradition, and Rimsky-Korsakov's use of them made his harmonies seem radical. Conversely, his care about how or when in a composition he used these scales made him seem conservative compared with later composers like Igor Stravinsky, though they were often building on Rimsky-Korsakov's work. Operas While Rimsky-Korsakov is best known in the West for his orchestral works, his operas are more complex, offering a wider variety of orchestral effects than in his instrumental works and fine vocal writing. Excerpts and suites from them have proved as popular in the West as the purely orchestral works. The best-known of these excerpts is probably "Flight of the Bumblebee" from The Tale of Tsar Saltan, which has often been heard by itself in orchestral programs, and in countless arrangements
