Watch the Grin & Tonic online guitar lesson by Brad Carlton from Chord Studies: Open String Chords Vol. 1

You’ll encounter the vi IV progression many times and when you find that progression in the key of E, insert following open voicings for maximum impact and ear-to-ear grins from audience and band members alike. Note that each chord type has two voicings, played on different parts of the neck. Watch those mutes carefully!
