The 5 Major Scale Positions, Connected With CAGED (A Complete Guide)
If you only learn one scale in your life, make it the major scale.
I think 95% of us know it’s the single most important thing you can learn as a musician (not just a guitarist) because everything else comes from it.
Your chords, formulas, intervals, and pretty much everything about music is traced back to this one scale.
This guide walks through all five positions of the major scale in G, the way I taught them across my video series. We’re staying in G major the whole way, so you’ll have plenty of room to roam without changing keys.
By the end you’ll have five connected shapes, you’ll see exactly how each one maps to a CAGED chord shape, and you’ll understand why that matters when you go to play.
Position 1: The Foundation (The E Shape)
We’re in G major, and position one lives across the second, third, fourth, and fifth frets.
The big thing here is the “one finger per fret” approach. Your index finger owns the second fret, middle owns the third, ring owns the fourth, and your pinky owns the fifth.
Assign each finger to a fret and you stop shifting around/losing your spot. Your root note is G, the third fret of the low E string with your middle finger.
Run it all the way up: G, A, B, C, D, E, F#, G, A, B, C, D, E, F#, G. And bam, that’s the whole pattern.
So learn the notes, but as a guitar player it’s even more important to learn the intervals.
The root is your 1, the next note is the 2. Then the 3, and that note is huge, because the third is what dictates whether a chord is major or minor. 4, 5 (another important one), 6, 7, back to the root.
How to practice it
Play the pattern slowly, say the interval number out loud for each note, not just the letter name.
Position 2: Connecting Up the Neck (The D Shape)
Position two picks up where position one ends. We steal the root note from the third fret of the low E, then slide up. Our next root note is way up there on the 10th fret of the A string, so we’ve got some ground to cover.
Same idea with the fingers remember.. designate fingers to frets so you’re not constantly shifting and losing your place.
The “aha” in this video is about your root notes acting like road markers. You’ve got G at the third fret of the low E, G at the fifth fret of the D string, and G at the eighth fret of the B string. They’re close enough together that you’re not hunting all over the neck for home base.
The other big takeaway is instead of staying boxed into position one, a lot of players (especially the speedier ones) like to combine position one and two into a three notes per string approach.
Instead of two notes on a string, you play three on every string from octave to octave. It’s smoother overall.
How to practice it
Find all three of the G root notes and bounce between them. Then try linking position one and two with three notes per string instead of staying in the box.
Position 3: The Comfortable One (The C Shape)
This is a position I really enjoy, and there are two ways into it. You can trek up to it from the third fret root, or, better, you can just start inside it, because this shape has a root note built in at the 10th fret of the A string.
There’s another root waiting at the eighth fret of the B string, too.
On the CAGED map, this is the C shape. The neat thing is that the C shape conveniently contains the D shape inside it. That’s why I don’t usually bother playing the D shape on its own because it’s already sitting right there in the C shape.
CAGED shows you where your chord tones live, specifically the 1, the 3, and the 5, and that changes how you solo. When you’re noodling over a G major chord and you go to end a phrase, you want to land on one of those chord tones (the 1, 3, or 5) to really solidify it.
Why? Well because the 2 and the 4 are suspensions and they want to resolve. When you land on the 2 or the 4, the ear is waiting for you to finish. The 6 is a bit of a culprit there, too.
The 7 is one of the few non-chord-tones that’s okay to land on, because the 7 extends the chord into a major 7, and a major 7 is really just an extension of a major chord.
How to practice it
Play the C shape G chord and identify each note as 1, 3, or 5. Then improvise in the shape and consciously end your phrases on chord tones. Pay attention to the difference when you land on a 2 or 4 instead.
Position 4: Intervals on a Single String (The A Shape)
Position four starts on a root note again, the 10th fret of the A string, and that makes it nice to get into.
The cool quirk here is that this position only has two notes on the A string, meaning you end up playing most of the scale on a single string. That’s a handy thing to know how to do, because it lays out all your interval distances in a straight line. If that’s your 1, here’s the half step, here’s the whole step, and so on.
On every string, find whatever scale you’re in and play it on just that one string. It’s how a lot of slide players work, and it gives you that very vocal quality, because instead of jumping all over the neck you’re making small adjustments within the scale the way the human voice does.
On the CAGED side, position four is the A shape.
A quick recap of the whole map so far:
- Position one was E
- Position two was D
- Position three was C
- Position four is A.
And the thing I really want you to take from CAGED is learning what interval each note in the chord is. Take a regular open G: run through it and you get 1, 3, 5, 1, 3, 1.
Major chords are just stacks of ones, threes, and fives. Once you see that, triads start making sense, because you know exactly which note to pull out when you want to add another.
How to practice it
Pick one string and play the full G major scale up it, naming the half steps and whole steps as you go. Then map a basic open chord by interval (1, 3, 5) instead of by note name.
Position 5: Closing the Loop (The G Shape)
This is the final shape, and it sits in a slightly awkward spot because of where the root note falls, but once you bring in the three notes per string approach it all comes together.
The root we use is the G octave up at the 15th fret of the low E.
Since we started in G and this position gives us the G shape, that means we’ve now crossed over every single CAGED shape.
The arpeggio for this shape outlines a regular open G chord. I like to throw in the “rock and roll G” by dropping the ring finger on the third fret of the B string, which adds another fifth and sounds great rolling through the arpeggio.
The bigger lesson in this video is the mindset shift. I don’t really think in these boxed scale patterns much anymore.
Instead, I view the fretboard in terms of three note per string shapes, cruising root to root, and coming down through arpeggios that link into the next shape. This particular three notes per string shape combines position four and position five, and it crosses three octaves in one scale shape while priming you to slide right into the next one.
A quick warning.. when you run a three notes per string shape, keep track of which fingers you use going up, because the biggest stumble I see is players using a different finger on the way back down. When you stay consistent, you trip over yourself wayy less.
How to practice it
Learn the position five box, then learn the three notes per string shape that links position four and five. Run it up and down and pay attention to your fingering on the descent.
Putting It All Together
Don’t try to memorize all five in a day.
Instead, get position one solid, then add the next. Then start connecting them, first with the shared root notes, then with the three notes per string shapes that link one position into the next.
The goal here isn’t five separate boxes (remember the mindset shift I mentioned above). It’s really about connecting the fretboard where you always know where your root, third, and fifth are sitting.
From there, take it off the page. Solo over a G chord and practice landing on chord tones. Then, play the scale on a single string, Then map your open chords by interval.
