01
Progression generation
Creates a fresh four-chord guitar progression quickly so you can start with something playable instead of building harmony from scratch.
StrumForge
Feature guide
Every major feature, explained in plain guitar-player terms.
StrumForge is built around fast progression generation, clear fretboard context, and enough control to keep the result musical. This page breaks down what each major feature does and why it matters once the guitar is in your hands.
- Generation and harmony controls
- Playback and practice tools
- Visual, layout, and accessibility features
Generation and harmony
Features that shape the progression itself.
02
Key control
Lets you lock a key when you want a specific tonal center or randomize it when you want the app to push you somewhere less familiar.
03
Mode selection
Lets you narrow the harmonic lane by choosing one or several modes, which changes the character of the generated progression and the matching scale view.
04
Shape filters
Limits the progression to open chords, barre chords, triads, or power chords so the result fits the kind of practice or writing you want to do.
05
Chord color options
Adds sevenths, suspended chords, and add9 voicings when you want more texture than straight major and minor harmony.
06
Chord locks and manual overrides
Keeps a chord you like in place or lets you replace one chord directly when the generated progression is close but not finished.
Playback and practice
Features that help you hear the progression and stay with it in time.
07
Groove playback
Runs the progression against a built-in groove so the chords feel rhythmic and musical instead of like isolated labels on a screen.
08
Tempo control
Slows the loop down for cleaner transitions or speeds it up when you want a tighter practice challenge or a more urgent writing feel.
09
Chord highlight timing
Highlights the active chord card while the loop runs so you can track the form visually and stay locked to the same pulse.
10
Guitar tone selection
Lets you hear the loop through different guitar voices when you want the playback to feel closer to the playing context you have in mind.
Visual and layout tools
Features that connect the harmony to the fretboard.
11
Chord diagrams
Shows each chord as a playable diagram so the progression stays tied to finger placement, not just chord-name recall.
12
Scale views
Displays mode and pentatonic scale shapes that fit the current progression when the session turns from rhythm work into soloing or melodic ideas.
13
Key-to-chord view
Lets you swipe from the scale panel to the chords inside the current key or mode so the relationship between theory and the progression is easier to see.
14
Move diagram positions
Lets you reposition chord cards when a different layout helps you read the progression more clearly or prepares your eye for the next change.
15
Landscape orientation
Opens up more horizontal room for progression tracking, playback context, and lower-panel theory views when you want a broader practice workspace.
16
Left-handed diagrams
Flips the visual layout for left-handed players so the on-screen diagrams match the way they approach the instrument.
17
Quick reset
Clears the current setup fast when the progression has drifted too far from what you want and it is faster to restart than keep patching it.
Why it works together
The value is not one feature by itself. It is the combined workflow.
StrumForge is most useful when generation, playback, diagrams, and scale context stay visible together. That is what makes it more than a random chord picker or a static chart viewer. It gives you something to hear, something to follow, and something to change without leaving the session.
