Why the piano makes theory visible
Every octave looks identical, half steps are always neighbors, and the black-key islands mark the map. What takes months to see on a fretboard is simply there on the keys — which is why theory is traditionally taught at the piano.
Fingering mode
For major scales, switch the display to Fingering for the standard right- and left-hand patterns — the thumb-under moments are where the numbers restart at 1. Drill the motion itself in the Technique room.
