Kamarinskaya: Kamarinskaya (Russian: камаринская ) is a Russian traditional folk dance, which is mostly known today as the Russian composer Mikhail Glinka's composition of the same name.  Glinka's "Kamarinskaya", written in 1848, was the first orchestral work based entirely on Russian folk song and to use the compositional principles of that genre to dictate the form of the music.
