Pick a key, a position, and a scale. Tap every fret that holds a matching note before the board is cleared — get one wrong and it flashes red. It's the fastest way to actually memorize where scales live.
A minor, 5th position, pentatonic — or any key, any of the scales guitarists actually use. The board resets to that shape.
Tap frets across all six strings. Each correct tap lights up and counts down from the total; a wrong one flashes red and stays wrong.
When every note is found, your results are summarized so the shape sticks — not just the score.
Learn where scale shapes actually live on the neck, one fret at a time, without a teacher standing over your shoulder.
Drill positions you already "sort of" know until your hands find them without thinking.
Hand it to a student as a five-minute warm-up, or use it yourself between lessons.
