How it helps
Use it for a focused task
Pick two scales, see them on matching fretboard grids, tap notes to hear them, and switch between note names, intervals, or scale degrees. Presets cover common pairings like pentatonic vs.
blues. A chord-tone overlay shows which notes fit a given chord.
Choose a root note and scale type for the left panel, then do the same for the right. The fretboards update instantly.
