Pick a key. Every note of the scale appears on the fretboard — nothing to click through, nothing to read. It sits on your music stand and stays quiet while your hands do the learning.
root scale note chord tone · that's the entire legend
The exact app that ships to desktop, running right here. Pick a key on the circle of fifths, set your tuning — drop C welcome — and cycle chords with ← →.
It remembers your key, scale, tuning, and layout between visits.
There is deliberately no text on the neck. You see intervals and positions the way your hands find them — as shapes anchored to red roots. Twelve scales, every key, chosen on a circle of fifths that shows you how keys relate instead of listing them alphabetically. And it's your neck: any number of strings, each tuned however you like — standard, drop C, 8-string, bass, or something only you play.
Pick any diatonic chord and every one of its tones lights up green across the entire neck — inside the scale you're practicing, not in an isolated chord box. Cycle I through vii° with the arrow keys and watch the harmony move while your hands stay on the guitar.
One keystroke collapses everything to just the neck. Zoom the whole UI until it reads from across the room. No navigation, no accounts, no streaks — it opens in your key from last time and waits. Desktop, browser, or phone in landscape.
