Watch the Major Scale Form II 2 online guitar lesson by Brad Carlton from Guitar Lab: Caging ii V I
This lesson focuses on playing and hearing the G Dorian mode in third position utilizing scale form II of the F major scale. Diagram 27 shows the arpeggio for the ii chord in the key of F. This chord is a Gm and is played with the Em form out of the EDCAG system. The remaining black degrees in this diagram form the G Dorian mode.
Example 21 demonstrates a two voice exercise in which the lower voice is the root of the Gm chord and the upper voice is a descending G Dorian mode.
