This exercise involves playing firstly an A major and then an A Lydian dominant scale in the 9th and 14th positions. Again we're working on smooth position shifts that start with gentle rotation of a neutral shoulder and progress to very slight lateral deviation, or rolling, of the wrist.
Start by playing the A on the 10th fret 2nd string with your second finger. Look away from your guitar, have a close listen to it before bringing your hand completely away from the fretboard. Again without looking down come back to play the same note. Practice this until you can freely associate the position of your hand in space with the sound you're hearing.
Now remaining in this position play up and down the first 5 notes of the A major scale. Again bring your hand away and do it again.
Nex play up to the octave to the 14th position and back down again. Ensure that your shoulder is as relaxed as possible, that your elbow isn't moving too much and that your wrist has a very subtle lateral translation as your hand rolls up and back between the 9th and 14th positions.
Repeat the exercise now using the A lydian dominant scale. This is a sound you may not be as familiar with so it'll kick you out of your comfort zone a little and it also requires a different fingering in both positions. It varies from the major in that the 4 is sharp (D# 11th fret) and the 7 is flat (G natural 15th fret), both by a half step.
