The C and G are just one strum only. Hit them quick and switch to the next chord.
*Am means that you strum open and then hammer onto Am (the entire chord)
The star * means a hammer-on on the A string while playing the Am chord
(Nothing) means don't strum until the next chord
(Mute) means to just strum the strings muted

Hope this isn't too confusing. It's easy to catch on. Enjoy
