Oops my bad, I couldn't find the right words in English sorry. Thanks for the correction Daniel.
What I meant by "ternary rhythm in 3 beats" was to distinguish rhythms like Konkoba or Koreduga from rhythms like Sökö or Soli.
It's important to notice the difference because many intermediates and sometimes advanced players who don't know the rhythm well will fumble with the accompaniment and will play Konkoba as though it was a more "regular" ternary rhythm.
It teaches me the valuable lesson I should get my vocabulary and ideas straight before posting more often, and get some basic musicology knowledge. I've always played without any knowledge of it because in my experience all the people focusing on it couldn't play well, and acquired mental barriers preventing them to learn the music (I know it's not a rule, but it was a common occurence at the time). But to communicate with others by text, I realize now it's better to not be completely ignorant of it lol.
