Every scale on this site is one the app actually drills, charted with the exact dots and
the fret window it puts under your hand. Each shape fits a six-fret window: four fingers
over the middle four frets, the index and the pinky sliding out to the two on the ends. The
hand stays put and only the fingering changes.
The Chromatic Box
Every scale you will ever play fits inside one six-fret window: four fingers over the middle four frets, index and pinky sliding out to the ones on the ends. These two exercises park your hand in that window and teach the discipline itself — first low on the neck where the open strings help, then anywhere you like.
The major scale — do-re-mi under your fingers, the reference every other scale and mode is heard against. One shape walks all twelve keys a fret at a time, then a second shape does it again, until any key is yours two slide-free ways.
