The balalaika is a central part of musical tradition in Russia. The balalaika is somewhat similar to the banjo. It is be triangularly shaped, or circular. The balalaika is most commonly used by gypsies, and is also a very popular instrument in Russia. Originally, it was established as a folk instrument in Russia around the 17th century. During the 19th century, it's popularity was threatened due to the introduction of the seven-stringed guitar and concertina, which influenced by Europeans. However, in the 1880s, Vladimir. V. Andreev rescued it. He was an aristocrat, a mucisian, and a folklorist. He designed a new, better sounding balalaika. He made the instrument more versatile and increased its quality, so it gained popularity. A very good amount of folk music includes the balalaika, and it is still used in many musical performances today.
