This etude builds foundational fretboard fluency by combining a major scale shape with a thirds interval pattern, reinforcing both horizontal and vertical navigation on the bass. By moving systematically through the Circle of Fifths, students not only practice transposing but also internalize intervallic relationships and key centers across the neck. The focus on clean tone, consistent muting, and calling out root notes or fretted pitches enhances muscle memory, ear training, and theoretical awareness simultaneously. It's a high-leverage exercise designed to train technique, theory, and aural skills all in one integrated routine.
