Got up early today, like 4:30 am, broke out my nylon string, and began playing eyes. Very similar to shakedowns. Even both 7th fret and 4th fret Emaj7ths. But for the lower 4th fret Emaj7 you really don't need the bass note and so it is an easy, lazy, fall off to the lower Emaj7th from the A just a fret above. I use a whole barre on all of these chords so that my index finger, right before the hand joining knuckle, carrys the weight of the chords by anchoring down the high E string for my reference point. It all becomes child's play in this way.
I play the chords and then try to get the Jerry noodles going. (What was in the video is really Bob's part.)
I really think this song was an eye opener for Jerry to work some really correct chromaticism. This is especially apparent when you go to the Emaj7 jam followed by the Bm jam.
For these two jams to be linked you are using an E major scale for the Emaj7 and then when the Bmin chord occurs you switch to the A major scale. You keep going back and forth between these two scales.
Here's where the correct chromaticism comes in:
9th fret E major scale
e|*| |*|*
B|*|*| |*
G|*| |*|
D|*| |*|
A|*| |*|*
E|*| |*|*
You mess around with the E and B strings and as you're coming down the key shifts to A major and you then have:
9th fret A major scale
e|*|*| |*
B|*|*| |*
G|*| |*|
D|*| |*|*
A|*| |*|*
E|*|*| |*
So, the high E string gets a descending run of all four notes as you go from the E major scale to the A major scale.
Although the E major scale has a hand shift to the lower 8th fret on the G string (not shown) for most manuevering, still you can see how closely related these two keys are, the E and the A major scales.
If you really play around with these two scales, all over the neck, you will quickly grasp what attracted Jerry to this intertwining. Not only that, but you will instantly hear the key shift on the not-in-common notes, especially if you imagine the Eyes jam.
It's too early and arduous for me to list all the other occurances of the chromaticism but the really neat thing is that you are playing inside the key the whole time since the chord change happens just an instant before the "wrong" note would be played, the chromatic run note.
