This simplified excerpt of an old classic gives us a glimpse into the Bossa Nova and Jazz styles.
Notice that in each bar we play the root note of the chord, followed by the Dominant (Perfect 5th) below it. So the chord is not changing throughout the bar, we're simply accenting a different bass note.
It's not so different from what Johnny Cash was doing in I Walk The Line!
