I notice some popular acts from seeing some of their books seem to play using a lot of triads with their guitar.

I have noticed that with acts like Pink Floyd.
Though occasionally there is something more complex.
Especially with a 12 string.

I have hit on to a Country type song sometimes without even realizing it. Or so I was told.
I was trying to play folk.
I normally try to play rock.
But to some folk sounds the same as Country for some reason.
I know little sheet music and that was quite awhile ago.
But it seems that Country seems to work more in the movement and rythmn of the chords than the chords themselves.

I'm not much into Country unless it is mixed with Rock.
But I like some contemporary Country.
The chords don't seem that hard.
It seems to be the rythmn and movements though.

I tried playing some of your notes, verse, chorus on keyboard.

Is there a certain rule with a given genre?
