Watch the III - IV - II - I Phrygian online guitar lesson by Robbie Calvo from Modal Expose
As much as I want you to learn some of the ideas I played in this solo and understand why, I truly think the learning begins when you work on your own sample solos. Creating melodies over some of the modal progressions will be a challenge to say the least and I want you to realize that it won't always be a walk in the park with Jennifer Love Hewitt - believe me, I wish it was!
My approach to this solo was to create a memorable melody, add some flourishes and play a scale based run to delineate the Phrygian sound over the chords.
You'll notice that I play a D major 7 arpeggio over the C# minor 7 chord in places and this works because the D is the Phrygian characteristic note, the C# is the major 7 of the D chord and the root of the C# and the 2nd chord in the progression is D major 7.
Try superimposing an A major 7 arpeggio over the C# minor 7 chord, you might dig it!
