Print out strum patterns from the resource page and practice the progressions with each strum pattern. Start with the down strums then move on to the other patterns. Your goal is to be able to switch between chords smoothly from one to the next.
Each track has one version without the guitar in the mix, so you can play your guitar along with it. Some songs have the chords or Tab included.
