Pentatonic Scale Inside The Major Scale On Guitar

This article post is about the Pentatonic Scale inside the Major Scale on guitar. The biggest confusion is what key am I really playing in.  When working with Seven note Major Scale Versus 5 note Pentatonic Scales. You need to know how do they interact and relate to each other.  In a live improvisation playing situations where your not sure of what key your playing in. The first thing your usually going to do by ear is find that common Minor Pentatonic Scale Box and see what chord changes are being played. You usually are not going to try playing any major scale 1/2 step notes until you are absolutely sure what major scale key your playing in.
Blues and Rock players on the other hand relate the key to the Minor Pentatonic Scale (The bordered notes shown in the fingering on the first row). Blues players usually stay in Pentatonic and Blues Scales and the diatonic major scale is not used much.
Here is the big kicker, three different Pentatonic Scale Keys can be super imposed on the major scale. The Minor Pentatonic Scale can be super imposed on the three minor modes of the major scale – (vi) Aeolian Mode or Natural Minor Scale, (ii) Dorian Scale, (iii) Phrygian Scale (1st row of the fingering diagrams). The chord progression order of the chords being played is what’s going to rule this relationship. The (G Major Triad Chord Scale Chart) shown below shows the major chord scale order and what relates to the scale fingerings below.
The (Diagram – Fret 5 A Dorian Scale Mode/ A Minor Pentatonic Scale) is the most common relationship found and it’s usually when the IV chord is Major. This one is common in a lot of I, IV, V. Blues & Rock Progressions. The next commonly found relationship is the Aeolian Scale/ Minor Pentatonic Scale. This usually is when the IV chord is minor.
The least common relationship is the (Diagram –  B Phrygian Scale Mode / B Minor Pentatonic Scale). This can happen if the IV Chord is Minor b6. The simplest overview of all of this technical jargon is to analyze the IV chords that is being played within the Minor Pentatonic Scale fingering. This gives you a clue to the notes of the major scale mode and what major scale key your playing in.
If a guitar player with a good ear has practiced both types of scales, they can usually find their way around both scales relationships easier. You can never stop getting better at scales. The more you practice and apply yourself to play each of these scale relationships in your solos. The better your is ear is going to become in adapting playing to different types of chord progressions.
