Most fretboard systems ask you to memorise five, seven, or even more separate shapes — one for each scale degree — before you feel fluent. This system takes a different approach: learn just two one-octave shapes for any scale, understand where the intervals sit within them, and you can play freely in any direction from any root on the entire neck.
What you’ll get out of this lesson
You’ll learn the Two-Point Intervallic System — two complementary major-scale shapes that, once internalised, let you navigate every key across the full fretboard. You’ll also understand how to tweak those shapes to convert them into any other scale or mode you need.
The Core Idea: Two Points, Full Coverage
The system gets its name from the two “points” — two positions in the hand — from which every scale shape can be built. Shape 1 places the root on the first finger and ascends the fretboard (uses frets the same or higher than the starting fret). Shape 2 places the root on the little finger and moves back down the fretboard (uses frets behind the starting fret). As the transcript puts it:
All you need to do, or you can get complete freedom from just knowing two shapes. Two general shapes, and then you can learn how to change them for every scale.
Those two shapes cover the full neck because every time you finish Shape 1, the hand naturally lands in position to begin Shape 2, and vice versa. Connecting them creates a seamless, scalable system rather than a collection of isolated boxes.
Shape 1: Root on the First Finger, Ascending
To understand Shape 1, place an A note on the 7th fret of the D string:
Build the major scale upward from that A with the root low in the hand (first finger). You get a three-note-per-string shape that travels forward and upward across the fretboard — visually, it has a forward diagonal quality, like a forward slash (/).
This same shape can then be used to descend from the original A as well. Note that where the shape crosses the G–B string pair, it shifts slightly — the G–B interval is a major third rather than a perfect fourth, so a small adjustment is needed. This is true for both shapes and is simply something to memorise per string set.
Between the ascending and descending versions, Shape 1 already covers a large sweep of the fretboard — travelling North-East (up and in) and South-West (down and back) from any root:
Spend some time with Shape 1 before moving on. Practise it with the interval numbers in mind (root = 1, major second = 2, major third = 3, and so on) — that knowledge is what allows you later to tweak the shape for any mode or scale.
Shape 2: Root on the Little Finger, Descending
Shape 2 begins with the root on the fourth finger (pinky) and uses the frets behind the starting point. It mirrors the diagonal direction of Shape 1, resembling a backslash (\) and travelling North-West and South-East from the root.
Here is Shape 2 used to descend. Notice that the shape completes after four strings, so you won’t have enough strings below for a full descending run in the same position:
For reference, here is Shape 2 starting on the A note on the 3rd string, showing how it sits on the lower four strings:
Again, practise Shape 2 with the interval numbers, and listen carefully to the sound of each degree of the scale as you play it.
Connecting the Shapes Across the Fretboard
The magic of the system is in the connection. Every time you finish Shape 1, your hand naturally lands in a position where the root is high in the hand — exactly the starting point for Shape 2. And every time you finish Shape 2, your hand is low in the hand, ready to start Shape 1 again. By chaining them together, you can travel fluently in any direction from any root note:
The practical approach is simple: find your root notes across the neck, then ask yourself — “can I build Shape 1 (ascending) from here, or Shape 2 (descending)?” Knowing both options for every root gives you complete coverage without ever memorising a third shape.
Shape Reference: All String Sets
Below are both shapes shown starting on every string set, so you can see how the G–B string adjustment affects each position. Study these carefully and refer back to them during practice.
Shape 1 starting on every string:
Shape 2 on every string set:
Taking it further
Once you’re comfortable with the major scale versions of both shapes, you can convert them into any mode or scale by tweaking individual intervals. For example, flattening the 3rd and 7th gives you Dorian; flattening the 2nd, 3rd, 6th, and 7th gives you Phrygian. Because you already know where every interval sits within the shape, these adjustments are logical rather than requiring you to learn an entirely new shape from scratch. This is the real power of thinking intervallically rather than shape-by-shape.
Your homework
Choose one key — A is a great starting point as there are clear reference notes across the neck. Find every A on the fretboard and practise building Shape 1 upward from each one. Then do the same with Shape 2 descending. Finally, try connecting the two: start with Shape 1, and when you reach the next root, switch to Shape 2. Work slowly, name the intervals as you play, and practise this daily for a week before moving to a new key.
