Unlock the entire fretboard with interactive drills for every shape, position, and inversion.
Stop being limited to open chords. Every CAGED shape plays the same chord in a different fret region. Learn all five shapes and the entire fretboard becomes playable. Go from one position to anywhere on the neck.
Forget bulky barre chords that kill your hand. Triads are just three notes on three strings—tiny, moveable, efficient. Drill recognition (see a triad, name it) and recall (hear a name, find it) until theory clicks. No confusion, just muscle memory.
Stay in one fret region and switch between three different voicings. Learn smooth transitions with minimal hand movement. Drill chord changes until your fingers know where to go without thinking.
Drill them in two directions: see a shape and name it (recognition), then hear a name and find it on the fretboard (recall). This trainer has both modes built in. Start with single chord drills in one key, then expand to all triads mode which randomizes across major, minor, augmented, and diminished qualities. A built-in hint system helps when you're stuck.
Learn all five CAGED shapes for the same chord. Each shape places the triad in a different fret region. The trainer's CAGED shape mode locks one shape at a time and challenges you to find every voicing it contains across all four string sets — then you move to the next shape until the whole neck is covered.
Use the progression lock mode. It drills I–IV–V changes in your selected key, picking close voicings so you switch chords with minimal hand movement. Instead of jumping across the neck, you stay in one fret region and learn the transitions that working guitarists actually use when comping in a band.
Start with strings 1-2-3 (the highest three) — they're the most common for rhythm and comping. The trainer covers all four sets: 1-2-3, 2-3-4, 3-4-5, and 4-5-6. You can toggle individual strings on or off to focus on the ones you find hardest. Each set gives the same chord a different tone — bright on top strings, warm on the lower ones.
No. The trainer has a 30-second interactive tutorial that walks you through triads, inversions, and CAGED shapes with examples on the fretboard. Theory clicks naturally through repetition — after a few dozen drills you'll recognize shapes by sight without thinking about intervals.
