FREE INTERACTIVE GUITAR TOOL
Explore scales, chords, intervals and note relationships across the guitar neck. See what the shapes actually represent, how they relate and how the same musical information connects across the fretboard.
Free to use • No signup required
Choose a root note and scale type, then use the finder to explore what that scale contains and how it is organised across the fretboard.
Select the note you want to use as the tonal centre.
Select the scale or mode you want to investigate.
Compare the notes, interval formula and fretboard layout.
Don't stop at memorising the shape. Look for the pattern behind the pattern — the interval relationships that make the scale transferable across the entire neck.

WHY THIS MATTERS
Many guitarists learn useful shapes and patterns without ever being shown clearly how the information inside those shapes connects. The shapes work — but they can become limiting if the underlying notes and interval relationships remain invisible.
THE AGS APPROACH
Once you can see the notes and intervals inside a shape, that information can move to different keys, positions, scales and musical situations. That is where memorised information begins becoming usable understanding.
Connect the information. Create with understanding. Transcend the limitations of isolated shapes.
SEE WHAT THE SHAPE CONTAINS
The fingering may change depending on where you play it, but the interval structure of the scale stays the same. That structure is what makes the scale recognisable in any key.
EXAMPLE
That formula remains the same whether the root is A, C, E or any other note.
THE IMPORTANT PART
Once you recognise the interval formula inside a scale, the fretboard becomes easier to transpose, connect and understand. The pattern stops being the destination and becomes a way of expressing the underlying structure.
FROM INFORMATION TO APPLICATION
Notes, intervals and patterns are not separate pieces of information. Once you begin seeing how they relate, the fretboard becomes easier to navigate, transpose and use creatively.
Recognise the same notes and interval relationships in more than one position instead of being locked into a single box.
Change the root while keeping the same interval structure, making transposition far more logical.
Use the relationships intentionally for phrasing, improvisation, melody and chord-scale connection.
Shapes are useful visual and physical reference points. The goal is to understand what they contain so you are no longer dependent on the shape itself.
READY TO GO DEEPER?
The Scale & Chord Finder lets you explore the relationships. The AGS Fretboard Mastery Course gives you the structured training to recognise, connect and apply them across the entire neck.
