-First try playing the minor pentatonic scale over this track to get a cool, dark, bluesy sound.  (The notes in WHITE BOXES on the even-numbered Blues key pages of any Complete Edition). 

-Next, try the Major pentatonic scale with the same track & you'll completely change the feel to sound warmer & more country-like. (All underlined notes in Complete & Essential Editions).

-Great blues players use both scales, often in the same song!

(underlined notes, pp. 9-10)

G minor pentatonic: GBb, C, DF (notes in white boxes, p. 10)

The whole goal of Fretboard Toolboxes is not to memorize all of the notes of each key, scale, and chord -- it's to help you build mental & visual maps of the common shapes you'll use for chords & scales, which leads to strong ear and muscle memory!

If you think of this progression as a V-IV-I in C Major, and play the C Major pentatonic scale, it sounds warm.  But if you think of it as a I-bVII-IV in G Major, you can play the G minor pentatonic (sounds dark) OR G Major pent. (also sounds warm)!

 Flat-7 chords (bVII) get used lots in all kinds of music including bluesy-rock, bluegrass, country, and more.  They're used WAY more often than the "real" 7 chord, called a "diminished" chord. 

Experiment with the G minor pentatonic, and then the G Major pentatonic (adding in some C & F notes) for different sounds!

 IMPORTANT: In Fretboard Toolboxes, any time you see a chord or a note in italics, it means that something is outside of the key. 

 Each "rule-breaking" note or chord has it's own sound.  When you recognize a rule is being broken, try to figure out how it's being broken & learn the unique soundof each "rule-breaker"!

This progression is another one that shows the power of scales to change the songs feel.  If you play the G Major pentatonic scale with this progression, it sounds warm & sweet.  However, if you play the G minor pentatonic scale, it sounds super dark! Try mixing and matching them and see what you come up with!

Noodle around with the minor pentatonic scale while this track is being played, and then notice which notes sound best over which chord.  The best sounding notes are most often part of the chord that's currently being played.  It's like this in all keys!
