ONE FRETBOARD. ONE CONNECTED SYSTEM.
See the Relationships — Not Just the Shapes
Scales and chords are often taught as separate subjects. On the fretboard, they are built from the same notes and interval relationships.
FretLab lets you move between those perspectives and see what is actually happening inside the shapes you already know.
Instead of treating a scale box as one piece of information and a chord grip as another, you can begin recognising the notes and intervals they share — and how those relationships continue across the neck.
THE IDEA BEHIND FRETLAB
Shapes Give You a Starting Point. Understanding Gives You Options.
The goal is not to stop using shapes. It is to understand what those shapes represent so you can move, adapt and connect them more freely.
NOTES → INTERVALS → SCALES → CHORDS → MUSIC
EXPLORE FRETLAB
Start With a Root. Follow the Relationships.
Choose a root note, then explore scales or chords from that same musical starting point.
Switch between notes and intervals, compare fretboard positions and voicings, and use the audio controls to hear the information as well as see it.
01

TAKE THE NEXT STEP
FretLab Helps You See It. Fretboard Universe Helps You Train It.
FretLab gives you a way to explore the notes, intervals, scales and chords that live across the fretboard.
Fretboard Universe is being built around what comes next — turning that understanding into structured practice, internalised knowledge and musical application.
01
FRETLAB
See It
Explore notes, intervals, scales, chords and fretboard relationships in one connected workspace.
02
FRETBOARD UNIVERSE
Train It
Move into structured practice, rhythm, timing, ear training, progression and the wider AGS learning environment.
03
MUSICAL APPLICATION
Use It
Internalise what you have learned so the information becomes something you can actually use when you play.
SEE IT → UNDERSTAND IT → TRAIN IT → INTERNALISE IT → EXPRESS IT

INSIDE FRETBOARD UNIVERSE
More Than a Fretboard Reference. A Place to Actually Train.
FretLab gives you the freedom to investigate the fretboard. Fretboard Universe is being built around the next stage: developing that knowledge through practice.
Rather than collecting more disconnected exercises and information, the aim is to bring fretboard knowledge, rhythm, ear training, practice tools and progression into one connected AGS environment.
01
PRACTICE
Structured Training
Move beyond looking at information and work with it through focused exercises, guided practice and deliberate repetition.
02
FRETBOARD
Scale & Chord Training
Take the relationships you explore in FretLab and begin practising scales, chords, positions and movement across the neck.
03
TIME
Rhythm & Timing
Work with tempo, pulse, rhythm and timing so fretboard knowledge develops inside real musical time rather than remaining a static diagram.
04
LISTEN
Ear Training
Strengthen the connection between what you see, what you hear and what you recognise before your fingers ever reach for a shape.
05
PRECISION LABS
Tools Where You Need Them
Precision Labs brings practical tools such as the tuner, metronome and tabs into the wider training environment as the system is completed and tested.
06
PROGRESSION
A Journey You Can See
Progression, achievements and the wider Fretboard Universe journey are designed to make development visible without losing sight of the music itself.
THE DESTINATION ISN'T MORE INFORMATION
The Goal Is to Remove What Gets Between You and the Music.
Notes, intervals, scales, chords, technique and ear training all matter. But they are tools. The deeper aim is to internalise them until they stop getting in the way of what you want to hear, feel and express through the guitar.
BE WITH IT → INTERNALISE IT → OWN IT → EXPRESS IT
Fretboard Universe is currently in development. Features will be introduced as they are completed, tested and ready to become part of the wider AGS experience.
