How does the Charango Scale Harmonizer work?

The charango is an Andean instrument with 10 strings arranged in 5 double courses. Its standard tuning is G-C-E-A-E (GCEAE), with the third course tuned in re-entrant octaves.

Select a root note and a scale to see all diatonic chords — triads and sevenths — with chord diagrams for every position on the charango fretboard.

Use the interactive fretboard diagram to visualize the full scale. Adjust tuning and fret count with the controls below.
