Balalaika

The best instrument for beginning of Russian ethnic week.

Some information from Wikipedia:

The balalaika is a stringed instrument of Russian origin, with a characteristic triangular body and three strings. The balalaika family of instruments includes, from the highest-pitched to the lowest, the prima balalaika, sekunda balalaika, alto balalaika, bass balalaika and contrabass balalaika. All have three-sided bodies, spruce or fir tops, backs made of 3-9 wooden sections, and usually three strings.

Early representations of the balalaika show it with anywhere from two to six strings, which resembles certain Central Asian instruments. Similarly, frets on earlier balalaikas were made of animal gut and tied to the neck so that they could be moved around by the player at will (as is the case with the modern saz, which allows for the microtonal playing distinctive to Turkish and Central Asian music).

In the 19th century the balalaika evolved into a triangular instrument with a neck substantially shorter than its Asian counterparts. It was popular as a village instrument for centuries, particularly with the skomorokhs, sort of free-lance musical jesters whose tunes ridiculed the Tsar, the Russian Orthodox Church, and Russian society in general.
