I hope every had a chance to check out the SAMI Chord Progressions map.  If not, it is right on the front of the home page.

 To those maybe a bit unfamiliar with chord progressions I can offer a simple idea for you.  Open up the chord progression map to the key of C.  Take the C chord and another random chord and start strumming those two chords back to back.  Getfamiliar with the sound.  Do the same thing with all of the chords.  The point is to use to your ear and begin to recognize what the chord changes can sound like.  

This is a great chance to experiment with different chord combinations and they are spelled out right in front of you.
