NA DVI STRANE KOLO
It is also called Po dva put drmavica. There is a unique tune (most probably originating from Pécsudvard) that belongs to the Bosnian dance Na dvi strane kolo. Some occurrences from the past should be mentioned here, when the left-moving Kolo divided, and moved symmetrically in both directions when the Kolo leader signaled it with the words Na dvi strane idemo!. We find parallel examples of other ethnic groups for the symmetric Kolo, which signifies the kinship.
It is danced by men and women in a closed circle with Kolo hold. We differentiate two versions of it. One keeps strictly to being symmetrical in the right-left movement. The other moves more to the left than right and the steps are not direction-symmetric.
Quite a lot of lyrics are known for the Na dvi strane kolo. They are interchangeable with the lyrics of Marice kolo, Okretanje, and Bećarac. Similarly to Marice kolo, where the 10-syllable-lines are lengthened to 13-syllable-ones by inserting the word Marice, the Na dvi strane kolo expands the ten syllables by the word ‘Ej’ into an 11-syllable line, and the proportioning of deseterac is 4/6. Based on this fact, we can place neither Marice nor Na dvi strane among the oldest dances.
Na dvi strane kolo is called Šklecalica by the Sokac from Olasz, and Trusa by people from Mohács. They consider it an old dance and dance it quite similarly.
The basic structure of Kolos, namely, two-steps-to-right followed by two-steps-to-left (or two left then two right), is widespread among other Croatian and Serb ethnic groups as well.
