Follow one note at a time
Hear the scale and follow the active note on the fretboard. Start slowly enough to place each finger cleanly, then repeat the shape without rushing the string changes.

Learn guitar scales across the fretboard
Go beyond memorizing a scale diagram. Follow the notes, understand the intervals, and connect familiar shapes across the neck.
Give the notes a name
Switch between Intervals, Notes, and Fingers. Learn where the root sits, recognize the scale degrees around it, and connect the pattern to the notes you hear.
Move beyond one position
Explore modes, pentatonic and blues scales, and CAGED shapes. Repeat a single shape or use the All playback option to work through the positions.
Explore the fretboard
See more in every scale shape
Change how notes are highlighted to focus on the sounds and relationships you want to learn.
Compare pentatonic scale shapes
Select multiple CAGED shapes to see their notes together across the fretboard. Here, the E and A shapes show two positions of G minor pentatonic.
See the triad inside the scale
Highlight the root, third, and fifth to see how a chord relates to the scale around it.
Find the notes that give a mode its character
Turn on modal color notes to highlight characteristic intervals in applicable modes, such as the natural sixth in D Dorian.

How to practice guitar scales with StrumForge
Choose a small target
Open StrumForge and choose a scale in the Scale controls. Start with G major and one CAGED shape. Keep interval labels on so you can find the root.
Set a comfortable pulse
With Pro, choose a slow playback tempo and quarter notes. Follow the highlighted note through the shape. Keep each note clear before increasing the pace.
Repeat, then change the view
Loop the shape until the route feels familiar. Switch to note names, or move to the next position and find the same root notes again.
Make it your session
Take the pattern back to the music.
Once you know a shape, give it a musical job. Open a chord progression in the same key and use a few scale notes to make short phrases. Leave space, repeat an idea, and listen to how the notes sit over each chord.

A few things to know
Does the guitar scale trainer play the notes?
Yes. With StrumForge Pro, scale-shape playback sounds the notes and highlights the current note on the diagram. You can adjust the tempo, choose rhythmic note values, and repeat a shape or work through positions.
Which guitar scales can I practice?
StrumForge includes modes, pentatonic and blues scales, and CAGED scale shapes. Choose a key and scale, then switch between interval, note-name, and fingering labels.
Does it listen to my guitar or score my playing?
No. The scale trainer provides diagrams, audio playback, and visual guidance. You judge your own note clarity and timing as you play along.
Can I use it on my phone?
Yes. StrumForge is available on iPhone, iPad, Android, and the web. The app is free to start; interactive scale practice and playback require Pro.
