After an inspiring lesson with Larry Goldings, and then studying out of Mick Goodrick’s “Almanac of Guitar Voice-Leading” volumes 1-3, I began working on some simple diatonic fourth sequences. This simple idea can be played in both a Lydian ( Major 7 #11) or a Dorian (minor 7) context, and is fairly easy to hear and sing as a melody.
I added a some rhythmic displacement for interest and to help move the melody away from a ” lick” and towards more of an intervallic sequence. The exercise is played in Lydian, in Dorian, then again displaced rhythmically and lastly through all the keys (around the circle of fourths). Also, learning to sing this melody is great ear training will help tremendously. Remember to stay relaxed, play slowly, listen carefully and take frequent breaks.
