The Domra

Domra is a long-necked Russian string instrument with three or four steel strings with a round resonator. It is thought that it was brought to Russia with the Mongolian invasion in 12th century.
The domra was redesigned in 1896 by Vasily Vassilyevich Andreyev. No exact descriptions of the original instrument remain.

The domra is played with a plectrum, and is used to play lead melody in Russian Folk Orchestras.
