Gankino – One dance Two rhythms
I always understood that Gankino was a dance in 11/16 -QQSQQ. The foot pattern is a variation of the Taproot Dance – basically the same as the T-9A [Click https://folkdancefootnotes.org/begin/the-taproot-family-t-4-t-6-t-8-t-7u-t-9u-t-11u/] but to a longer, faster rhythm.
Gankino in 9/16
The same footwork pattern as the basic Gankino, what I call a Taproot T-9A, can be found in Macedonia (Devetorka) (See https://folkdancefootnotes.org/dance/a-real-folk-dance-what-is-it/about/devetorka-macedonia/ ), Greece (Šareni Čorapi) (see https://folkdancefootnotes.org/dance/a-real-folk-dance-what-is-it/1st-generation-dances/childrens-dances-1st-generation-or-living/sareni-corapi-childrens-song-dance-in-9-8-macedonia/, and Serbia (Niska Banja), See https://folkdancefootnotes.org/music/about-music-types-songs-etc/niska-banja-serbia/ danced to a 9/8 or 9/16 rhythm. It seems Bulgarians call it Samokovsko horo, and are beginning to call it Gankino.
