The music for "Nobody Knows You When Your Down and Out" by Eric Clapton is written in the key of C but most of the chords are played as major and/or dominant sevens.
C E A Dm A7 Dm F F#dim7 C/G A7 D7 G7 C
Please help me understand how that fits into the basic harmonized major scale, I ii iii IV V vi vii.
This song is based on an advanced concept that stems from the chord progression number system I teach in my guitar theory method. Just be sure to master the basic concepts before venturing into advanced areas like this. Music theory is a process, you know.
Jazz players like to play over dominant seven chords. Now, there's only one seventh chord in a key (see Fretboard Theory chapter 10). But, who says you can't change keys and play over the V7 chord each time? Well, which keys go good together? What if you take the intervals from the major scale and play each of them as a dominant seven chord? The key of C would become:
C7 D7 E7 F7 G7 A7 B7
1 2 3 4 5 6 7
So this chord sequence is actually a series of key changes. Each seventh chord is a V chord from a different key. But we used the C major scale structure as a guide to determine which keys to combine. If you want to solo over these chords, you'll have to switch the parent major scale for every chord. Yikes, that's a lot to keep track of! But jazz players love it.
Progressions in this new sequence are the same as the diatonic scale but now everything is a 7th chord. For example:
I IV V
I7 IV7 V7 (Most blues songs are based on this.)
I vi ii V
I7 VI7 II7 V7 (A foundational jazz progression.)
You can hop around however you want. You can even switch back and forth between 7th chords and the diatonic chords (I ii ii, etc.).
The F#diminished chord is basically an F7 chord with the root raised. This chromatic passing tone bridges the gap between the F7's root and the C7's fifth (hence the C7/G).

This is what I like about your course. You continually try to enhance the content after the sale. Most do not.
Hey everyone - If you haven't started you should start paying attention to this guy. I have learned leaps and bounds and most importantly opened doors to my playing. I have the complete DVD set and fretboard theory book. I practice now more then ever and of course try to incorporate these principles and ideas into my playing. My friends are amazed when I show them concepts I have and am learning. They are too buying up Desi Serna Material. Enjoy and learn..

I was a guitar player a long time ago (almost 40 years) and I learned it all the WRONG way because I was also a keyboard player who practiced endless scales etc. So when I picked up the guitar again at age 55, I was thinking in terms of a linear keyboard. Desi's book made everyhting relate to the fretboard and the grid system. I still have to practice and the fingers are rusty, but the book helps me over all of those hurdles. It makes sense! His support materials are also excellent and he really does answer his emails!!! A Must Buy!!!
Start paying attention to this guy and you'll be a better player in no time .... it still takes practice, but you'll be working on songs and you'll understand why!
Just as a side comment, my son is 19 and he saw me playing my old guitar and he STOPPED Guitar Hero and now plays for real ... also using Fretboard Theory ... so you folks who worry about your kids doing too much video gaming, here's an answer ...FretBoard Theory and a real guitar
