The Tale of Tsar Saltan (Opera) - The Flight of the Bumble-Bee

Nikolai Rimsky-Korsakov (18 March [O.S. 6 March] 1844[a 1] – 21 June [O.S. 8 June] 1908) was a Russian composer, and a member of the group of composers known as The Five.[a 2] He was a master of orchestration. His best-known orchestral compositions—Capriccio Espagnol, the Russian Easter Festival Overture, and the symphonic suite Scheherazade—are staples of the classical music repertoire, along with suites and excerpts from some of his 15 operas. Scheherazade is an example of his frequent use of fairy tale and folk subjects.  [source from Wikipedia]

This work comes from the opera, The Tale of Tsar Saltan, of the Russian composer Rimsky-Korsakov. It describes the scene that the prince changes into a bumblebee to attach the enemy. The performers frequently use this music to show their skills due to its rapid medoly.
