ONE FRETBOARD. TWO WAYS TO EXPLORE IT.
See the Relationships — Not Just the Shapes
Scales and chords are often learned as separate subjects.
But they are built from the same notes and interval relationships.
FretLab lets you explore both sides of that connection — so instead of memorising another isolated scale shape or chord grip, you can begin seeing what the shape actually represents.
NOTES → INTERVALS → SCALES → CHORDS → MUSIC
