Watch the 123 Dorian online guitar lesson by Brad Carlton from Chord Studies: Modal Progressions Vol. 1

Here we use the 1st, 2nd and 3rd strings to achieve a Dorian sound. As you are playing these chords, go ahead and pick through each note as well as strumming them, this not only breaks up a rhythm part, but helps you start identifying melodic target notes that you would want to play if you were soloing or building a melody over a similar progression.
