Folk music rhythm usually follows _____ patterns.

Answer 1

I'm guessing the blank here is "metric." If not, perhaps the word "accented" might also apply.

Answer 2

Folk music usually follows improvised patterns and is often passed down through transmission rather than written. Recently, folk music has been passed down on sheet music but when it was first created it was improvised and often worked off of the other music styles and was passed down orally.
