Fretboard Reference

A public reference for the guitar and bass fretboard views used by the Barely Harris practice tools. The interactive trainers use this shared layer for labels, dots, protected answers, and playback behavior.

Guitar Reference The suite uses the shared fretboard layer to show voicings, roots, intervals, ghost notes, and answer targets on six-string guitar.

Bass Reference The same layout rules support lower-register string sets when a tool needs bass-oriented note and interval patterns.
