Caren covers this in detail on this lesson of the tutorial.

The trick is to avoid strumming the strings on some of those strums.

Down (strum) up (miss) down (strum) up (strum) down (miss) up (strum) down (strum) up (strum)

[quote=Dave Nightcaps]So when do I change chords

You change chords every 2 measures. So you complete that strumming pattern twice (once for each single measure), then change chords. Hope that helps!
