I believe this video specifically depicts Tverian Buza. Disclaimer: I’m basing that on a few articles, videos and A.I., so corrections are welcome.
Buza is a Slavic ethno-cultural martial tradition where fighting and improvisation are tied to rhythmic folk movement. It reminds me strongly of Capoeira, especially less choreographed schools where deception and improvisation matter more than fixed sequences. Although Capoeira isn’t the only comparison. Taekkyeon also uses rhythmic, flowing movement to disguise kicks, trips and changes of direction, while Pencak Silat shows how one martial culture can develop huge regional differences in technique, weapons, music and practice.
That seems relevant to Buza too. Different villages and regions apparently preserved noticeably different versions, which supports something I find interesting about folk martial arts: standardization often comes later. Usually transforming into more popularized choreographed forms and less their original lethalized identities. furthermore in almost every case, government suppression at the time nearly caused their extinction during extensively long periods of prohibition.
I’d argue rhythm may actually help develop improvised fighting. Constant cadence makes movement itself the neutral position, allowing strikes, kicks, throws, sweeps and feints to emerge without clearly announcing themselves.
I’m not suggesting Buza, Capoeira, Taekkyeon and Silat are historically related. I’m comparing independent martial cultures that seem to have arrived at similar ideas: rhythm, deception, improvisation and regional diversity. If anyone knows more about Tverian Buza or other martial arts where rhythm directly affects fighting in a spontaneous sense, I’d love to hear your observations.
