oh ya the modal chord progression I forgot, try this. You want to use a C Dorian scale to do a solo, and you want to really bring out the flavor of the Dorian mode. In which major scale is C the second note? Well that would be Bb Major (Bb, C, D, Eb, F, G, A ,Bb). Now to make a simple chord progression grab the 4 and 5 chords from this Bb scale. So now we Eb Major for the 4 chord and F Major for the 5 chord. Now throw the root note of the mode on the bottom of these chords to create the bass notes, so now we have C over EbMaj and C over FMaj (I would just play the major chords as triads with a C bass note) Record this progression and play the C Dorian mode over top as a solo, presto instant mood and endless soloing options. Hope this helps and dont forget to do this with all the modes as well. Happy soloing.
