CAGED Trainer
Learn the neck, one shape at a time. Five shapes, every key, same system — and the schedule that makes it stick.
60 seconds, then play
1. Pick up the guitar.
2. Tap the answer you think is right. Guessing is how it sticks.
3. Stop at 10 minutes. Come back tomorrow when shapes are due.

Today's practice circuit
Four focused stops. Scored answers count automatically; guitar exercises log self-rated practice. Recommendations use your last 20 scored answers per skill (after at least five). You can mark stops manually. Completion is not proof of mastery.
A focused mix of five fretboard targets and three ear questions. The weaker recent skill goes first; the other stays in rotation. Answers are scored in their original labs.
Ready to build your session.
Unlock the fretboard
No note knowledge required. First discover three landmarks on one string, then find them from memory. More strings unlock as you learn.
Let the app hear your note
Choose a target above, tap Start listening, then pluck one clear note. The microphone is used only for live pitch detection; nothing is recorded or uploaded. Requires HTTPS and microphone permission.
Microphone off.
Bring your own song
Load an audio file from your device. It stays on your device: no upload or online account. Mark a chorus or riff, loop it, slow playback, and write down the chord movement you discover.
No song loaded. MP3, M4A, WAV, or other browser-supported audio.
Notes and section markers save locally for this browser. Audio files are not stored; reselect your file after reopening. Browser playback-rate processing may change sound quality.
C shape in C
Amber dots are roots. Tap any dot to hear that note — that's ear training built in: hear it, see where it lives, then find it again.
Amber = root; blue = other chord tones. Filled circles are notes in the selected playable voicing. Full neck is an overview; slide view keeps finger targets large.
10 minutes a day beats an hour on Sunday
One shape at a time. Quiz first, then check.
Come back when it's due. Rusty is good — that effort is the learning.
Play a real song that uses the shape. The shape is the map; the song is the reason.

Scales & arpeggios
Explore a scale or chord-tone arpeggio in any key. Highlight a CAGED position, hear notes in order, and practice finding them. Positions are windows, not invented fingerings.
No patterns practiced yet.
Major ↔ minor CAGED
Compare the same root in major and minor. The third changes by one semitone. Every displayed dot belongs to a specific chord voicing; muted strings stay muted. Some C and G forms are challenging or partial.
R = root · 3 = major third · ♭3 = minor third · 5 = fifth. This lab explores voicings, not prescribed fingerings. Keep the first fret reachable when you play.
Position Bridge
One root and one CAGED area, three connected views: chord voicing, arpeggio and pentatonic scale. The highlighted area is a practice window, not a prescribed fingering.
Find the root on the neck, then check your answer.
Guided Position Journey
Play a chord, find its tones, add pentatonic notes, then connect to the next CAGED shape. Practice is self-assessed.
Ready to begin.
From Note to Music
Turn a fretboard target into a playable idea: locate it, hear its role in a chord, then play a short phrase. A weak recall target is suggested when your practice history supports one.
Build an exercise to begin.
Metronome stopped. Start it to practice with a steady four-beat pulse.
Rhythm Challenge
Hear four count-in beats, then tap the five note attacks in time. The timeline marks attacks (●) and space (—); this tests tapping, not guitar audio.
Choose a rhythm, then start.
Choose a rhythm and tempo, then listen for the rests.
Voice Leading Lab
Move between two chords with minimal finger travel. These are playable three-note triad inversions on adjacent strings—not full six-string CAGED shapes.
Voice-Leading Progression
Play a complete progression using adjacent-string triads near one position. Amber marks the current chord; blue shows the next chord. Shared tones stay close while the other voices move.
Build a route to begin.
Fretboard Recall Lab
Find the requested note on the indicated string. Tap a fret to answer; answers are scored automatically. Choose 0–5, 0–12 or 0–24 frets. The target is a pitch class, so octave equivalents count.
Adaptive practice starts balanced and prioritizes weak areas as you answer.
Press New question to begin.
Choose a fret to answer. No microphone required.
Interval ear training
Hear two notes, identify the distance, then reveal the answer. Start with three choices and expand to the full set when ready. Your quiz accuracy is tracked separately from physical guitar practice.
Press New question to begin.

Mastered means 3 correct retrievals on 3 different days. A miss brings the shape back tomorrow.
What is improving?
Recent accuracy is not a mastery grade. Trend compares the newest answers with the preceding answers when both groups have enough data.
