Master 3 Notes Per String Scale Shapes Across the Entire Fretboard

If you’re feeling limited by the CAGED system when it comes to speed, legato, and moving fluently across the fretboard, 3 Notes Per String (3NPS) shapes are the answer.

In this lesson, we break down how 3NPS scale shapes work and share a simple formula to help you memorize and map out all 7 shapes across the entire neck – without having to memorize 7 completely different patterns from scratch.

We’ll cover:
๐ŸŽธ How interval sets repeat across the fretboard
๐ŸŽธ The “Go Back 2 Sets” rule for instant visualization
๐ŸŽธ How 3NPS shapes relate to the 7 modes and chord contexts
๐ŸŽธ Practical 2-string combination exercises to break free from box patterns

Memorize The Guitar Fretboard Using These 2 Shapes

Do you only know the notes on the low E and A strings, while the rest of the fretboard feels a bit foggy? Or maybe you’ve tried memorizing it string-by-string, and it just never stuck?

In this lesson, we’re going to fix that. You’ll learn a highly effective, visual method to unlock the entire fretboard using just two simple triangle shapes.

Instead of memorizing blindly, this method forces your visual memory to work for you by making smart leaps across the neck. It’s a complete game-changer for your soloing, chord building, and overall confidence on the guitar.

Keep in mind: even though it’s a straightforward visual method, it’s not magic! You’ll still need to invest just a few minutes of consistent daily practice to let it truly sink in.
Stick around until the end of the video, where I’ll share a powerful metronome routine to help you fully internalize this and achieve true fretboard mastery.

Guitar Triads Crash Course: Master Fretboard Visualization

Triads are the ultimate guitar tool.
Think of them as lean, 3-note chords that enable you to move across the neck with zero effort.
They are the secret outlines behind legendary solos, from the melodic lines in “Sultans of Swing” to the epic phrasing of “Comfortably Numb”.

In this crash course, we break down the exact logic of Major and Minor triads, and jump straight into 3 practical case studies with TABS on screen so you can start playing them today.

The Logic Behind the B.B. King Box: Mixing Major & Minor Pentatonic

In this lesson, weโ€™re breaking down the logic behind one of the most iconic shapes in blues history: The B.B. King Box.

A lot of you liked the B.B. King solo I shared a while back and asked how it works, so I decided to go deep into the theory and fretboard logic behind it. Weโ€™ll explore how this “Box” acts as a perfect hybrid between the Major and Minor pentatonic scales, and why itโ€™s a “guaranteed recipe” for a professional-sounding blues solo.

What weโ€™ll cover:
โœ… The difference between Major and Minor pentatonic flavors
โœ… How to visualize the B.B. King Box using anchor points
โœ… Why this shape works over all three chords of a 12-bar blues (A7, D7, E7)
โœ… The “Secret Sauce”: Adding chromatic approach notes for more expression
โœ… How to transpose the box to any key

The 7 Guitar Modes: From Brightest to Darkest (Fretboard Logic)

Stop memorizing finger patterns and start choosing a musical palette. ๐ŸŽจ

If you’ve struggled to use the guitar modes in your solos, it’s probably because you’ve been looking at them in the wrong order.
Instead of introducing the modes by how they appear in the scale, we’re going to look at them through their color and mood.

In this lesson, we map out the 7 modes from the brightest and most uplifting (Lydian) to the darkest and most tense (Locrian). By understanding the “brightness scale,” you can choose the exact mood you want to project over any chord.

What we cover in this video:
๐ŸŽธ Why modes are like a color palette for your improvisation.
๐ŸŽธ The difference between Major-type and Minor-type modes.
๐ŸŽธ Detailed breakdown and examples for Lydian, Ionian, Mixolydian, Dorian, Aeolian, Phrygian, and Locrian.
๐ŸŽธ The ‘Drone Challenge’ to help you master these sounds.
๐ŸŽธ The Brightness Scale (Top to Bottom):
Lydian (#4), Ionian (Natural Major), Mixolydian (b7), Dorian (Natural 6), Aeolian (Natural Minor), Phrygian (b2), Locrian (b2, b5)

Stop Memorizing Modes! Use the Parent Scale Method

If youโ€™ve struggled to memorize endless neck diagrams and charts for the 7 modes, youโ€™re not alone.
In this video, Iโ€™m showing you a much simpler way: The Parent Scale Method.

The core idea is simple: You already know all 7 modes because they are simply hiding within the major scale patterns you already play.
By shifting your perspective and finding the parent major scale, you can unlock all 7 modes across the entire fretboard using just Major shapes.

In this lesson we talk about the biggest mistake guitarists make when learning modes, the relationship between the Major scale and the modes, and learn a practical way to play all 7 modes derived from the Major scale: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, and Locrian.
