About the guitar practice app
Know your fretboard. Find your next idea.
StrumForge brings songwriting and guitar practice together. Create chord progressions, explore triads and arpeggios, and hear how scales connect to the music you play. Add sampled drum grooves to your chord loops for a steady play-along backing.
- Turn a blank page into a playable progression.
- Connect chord shapes, intervals, and melodies across the neck.
- Keep your practice tools together, from tuning up to playing in time.
Why StrumForge
Make the connection between knowing a shape and making music.
A chord diagram tells you where to put your fingers. The next step is hearing where that chord can go, finding its notes elsewhere on the neck, and playing it with confidence. StrumForge puts those steps within reach in one app.
Theory you can see and hear
Pair fretboard diagrams with playback. Open Rhythm with the drum-kit button to choose a groove; with Pro, simplify the kit and lower Guitar volume to play your own part over the drums. Connect a triad inversion or arpeggio pattern to its sound, then use it in your own playing.
Less switching, more practice
Move between progressions, trainers, scales, metronome, and tuner without assembling a separate collection of practice apps.
The toolkit
Six ways to move your playing forward.
Guitar chord progression generator
Explore keys, modes, styles, and voicings with instant playback and drum grooves. Lock your favorite chords and refine the rest to start a song or build a practice loop.
Triad trainer
Learn major, minor, diminished, and augmented triad inversions across string sets. Find compact voicings for smoother rhythm parts and a clearer view of the fretboard.
Arpeggio trainer
Practice CAGED shapes and seventh-chord arpeggios with fingerings, TAB, and timed playback. Follow the same highlighted note on the fretboard and TAB. Learn to target chord tones when building a solo or melody.
Interactive scale tools
Explore scale diagrams, note names, and intervals with playback. See how patterns and chord tones relate so you can move beyond memorizing a single box.
Full-featured metronome
Shape your practice with time signatures, beat accents, subdivisions, and swing. Work slowly on accuracy, then build control as you raise the tempo.
Guitar tuner & alternate tunings
Tune up in standard tuning or explore presets such as Drop D, DADGAD, and Open G. Use reference tones and adjustable reference pitch to get ready to play.
Where it fits
A practice companion for the music you want to make.
Tab libraries help you learn existing songs. Guided lesson apps give your learning structure. StrumForge gives you a flexible space to apply those skills: create your own harmony, explore the fretboard, and practice at your pace.
After a lesson
Take a new triad, scale, or arpeggio into another key and hear it in action. Turn something you have just learned into something you can use.
When writing a song
Find a progression, compare chord shapes, and experiment with the groove. Let playback carry the harmony while you try a vocal line or guitar part.
When practicing lead guitar
Loop a progression and connect scale phrases to the changing chords. Use the trainers to find new places to land across the neck.
Make room for daily practice
Open it where you play.
