Once again, when you are comfortable with the fingerings for the Dorian mode, practice each form using intervals and sequences, and then try creating your own licks. These three licks are derived from the C Dorian mode. Each one is played over a minor seventh chord. The Dorian mode can also be used to play over minor, minor sixth and minor ninth chords. Try playing these licks along with some of your own against the Dorian jam along progression on page 202 (CD2 Track 48).
Once you have learned a mode in one key, play It in other keys by moving it up or down the fretboard. Here is a solo derived from the D Dorian mode. There are only two chords here - Dm and G. These can be analysed as I and IV in the key of D minor. The Dorian mode can be used for improvising over any progression in a minor key where chord IV is Major, or Dominant.
