Watch the I vi ii V Etude Level 3 online guitar lesson by Vicki Genfan from Open Tuning Handbook: Rhythm
Check out the new voicings first. Get your fingerings in place. Remember that while changing to the last chord (V), you can simply slide your ring finger all the way to the 9th fret on the 4th string. When sliding like this, lift the pressure up so your finger is ever so lightly touching the string. How are you doing with the mute in the strumming pattern? You can use a pick – or just your fingers, like me.
