Watch the Fourths, Fifths, Sixths: 6 online guitar lesson by Robbie Calvo from SoloCraft

Take a look at the fretboard diagrams and you will see we are using the same information as our previous classic 6ths module but adding a chromatic line to the 3rd and 1st string major 6th double-stop. You will also see the double-stop shapes within the chord shape found at the 3rd fret ( C7) and the 5th fret (D7). Remember this is a great way of identifying and finding double-stop shapes when improvising or transposing these ideas to different chords and keys.
