Five diagrams to memorize
Useful positions, but the relationship between them can be hard to see.
See the pattern
A guitar scale finder that turns the whole neck into fewer patterns.
Stop memorizing disconnected boxes. Choose any scale, mode, or tuning and Fret Prism reveals the repeating shapes that connect across your fretboard.

The core idea
Learn the connection, not another collection of boxes.
Most scale charts stop at separate positions. Fret Prism looks for what repeats, so you can understand how the same musical shape travels across the neck.

2 repeating shapes in this example
See where each shape returns and how it joins the next one across the fretboard.

How it works
From a scale name to the whole neck.
Start visually. Turn on note or interval labels when you want to understand the theory underneath.
Step 01
Choose your sound
Select a root, a scale or mode, and the tuning on your guitar.
Step 02
Reveal the repeat
Fret Prism analyzes the notes and finds a reduced set of recurring shapes.
Step 03
Practise the connection
Follow the shapes across the neck, listen to the scale, and explore its chords and arpeggios.
Popular starting points
Pick a sound you already know.
Jump into a familiar scale, then explore how its patterns repeat beyond the position you normally play.

More than a diagram
One musical idea, seen from every angle.
Connect scales to harmony
Explore chords and arpeggios formed from your selected scale. The example below is a real solver-verified fingering, not a decorative chart.
Change the lens
Switch between note names, intervals, and scale degrees as your understanding grows.
Use your tuning
Patterns are recalculated for alternate tunings instead of pretending the standard shapes still fit.
Connect the fretboard
Move beyond one familiar box by seeing where recurring shapes return and overlap.
Hear and practise
Listen to the result and turn a visual pattern into a musical habit with built-in practice tools.

Where are you stuck?
Fret Prism meets you at the problem you are trying to solve, not at a prescribed theory level.

Questions
Before you start.
The short version: choose a sound, look for the repeat, and start playing.
What is a guitar scale finder?
It is an interactive tool that maps the notes of a chosen scale onto the guitar fretboard. Fret Prism goes further by showing the recurring shapes that connect those notes across the neck.
How is this different from a scale chart?
A static chart usually presents one key, tuning, or position. Fret Prism calculates the result for your choices and helps expose the relationship between positions.
Does it work with alternate tunings?
Yes. The fretboard patterns are recalculated for the selected tuning rather than simply moving a standard-tuning picture.
Do I need to know music theory?
No. You can start with visual shapes and note labels, then switch to intervals and scale degrees when you want to understand more.
