In a song for example, a jazz standard, when I play the chord progression written down, do guitarists usually just strum that chord once and let the chord ring for however long the chord lasts for? Or do you kind of make up your own strumming pattern?

Thanks in advance.
I normally make up a strumming pattern. I like to put some arpeggios in too.

Is it lame to quote yourself in your sig?
Usually you would make your own strumming pattern, but keep to the beat. Sometimes It will have a pattern shown however.
