Rock and Roll features power chords. Funk features 9th and 13th chords. Blues features 7th chords. Jazz features all kinds of strange diminished and augmented and suspended and flat 5th and other unusual chords.
Country music (aka Country and Western) features mostly very basic major chords with an occasional minor chord thrown in to spice things up. Very rarely do I see Country songs that include any exotic or unusual chords other than embellishing a D major chord by adding or subtracting a finger to play a Dsus4 or Dsus2. And I do occasionally see a 7th chord thrown in as a passing chord - but not so often.
Why do country music writers and composers avoid the more complex chords such as the ones used in other genres? Certainly Brad Paisley or Keith Urban could play any chord they wanted to. Is there something inherent in the fabric of Country music that falls apart if you deviate outside the basic major and minor chords?
Are there good examples of country artists/writers/composers who regularly deviate from this "norm"? Or at least a few songs that squarely fall into the accepted definition of the "Country" music genre that feature more complex chords?
Before anybody goes there - the band America - is a Rock band formed in England according to Wikipedia - although some of their lyrics might cross over into what we expect in a "Country" song.
