How to Practice Bb Augmented Triads

Play the shapes on one string set from the nut up: root position at fret 2 first, then the next inversion, then the next — say the inversion out loud as you land on it. Then lock one fret region and switch between string sets instead. When the shapes come without thinking, test yourself in the trainer: it will flash Bb Augmented voicings for you to name, or name them for you to find.
