Watch the ii iii Progression online guitar lesson by Brad Carlton from Guitar Lab: Latin Rock Lead
Jam track number six consists of two chords: Dm and Em. The Street key for this progression is D minor. Approach number one for soloing over these chords would be to use a D minor pentatonic scale. Approach number two for soloing over these two chords would be to view the theoretical key which would be C major. This is because the Dm and Em chords are a ii iii progression in the key of C. The respective modes would be D Dorian and E Phrygian. Diagrams five and six show these two modes with the arpeggio tones labeled in red scale degrees.
