Master CAGED shapes through Triads.
Every CAGED shape maps the same chord to a different neck region. Guitar Triads drills all five until the whole neck opens up.
See a voicing — name the shape, inversion, quality. Hear the name — find the frets. Two-way drilling builds real fretboard fluency.
Lock to a blues progression. Practice triads as they actually move through a song — not as isolated shapes in a vacuum.
