Check out this Russian bard music here.
Bard poetry is generally accompanied only by a Russian guitar to maintain simplicity of the music so that the lyrics take prominence. The Russian guitar itself is an interesting and unique aspect of bard music. Unlike an ordinary six-string guitar, the Russian guitar has seven strings, and in Russian is often called a семиструнка, a nickname derived from семиструнная гитара (seven-stringed guitar). The tuning of the семиструнка also differs from the standard tuning (E-A-D-G-B-e) of a six-string guitar; instead it is tuned to an open G-chord (D-G-B-d-g-b-d).
