Watch the I IV bIII bVI Etude Level 2 online guitar lesson by Vicki Genfan from Open Tuning Handbook: Rhythm
You should be used to moving around the fretboard from Level 1. Now we'll bring in a strum pattern. We're also "fattening" up the chords a bit by adding a fingered note on the 4th string. You'll have an opportunity here to practice using your thumb to mute the 6th string. This is an invaluable skill that you'll use in so many songs! Another skill you'll get to work with is "preparing" for the next chord – leaving the previous chord a little bit early so that you can get to the next chord and stay in time. (SO important!) Remember to break things down into small pieces – sometimes just one chord change at a time.
