Watch the 7th Chord Voicings online guitar lesson by Brad Carlton from Guitar Lab: The Imaj7 VIIm7 Progression
We'll base our areas of activity on the fingerboard around the 5th and 6th string rooted chord forms for each of the 2 chords in this progression. Throughout this course, you'll have diagrams for various arpeggios, modes, and pentatonic subscales aligned with these 5th and 6th string rooted chord forms.
Our street key is D. Therefore, the title of this course, which is "The Imaj7 VIIm7 Progression", yields a Dmaj7 C#m7 chord change. This would be determined by looking at Chart 1 and going down to the key of D, which would then reveal that D is I and C# is VII in the key of D. The labels of our formula establish the roots of the chords, and then the chord qualities are defined by the major 7 and minor 7 harmonic labels. Diagrams 1-4 show the chord voicings for these two areas of activity on the fingerboard.
