How does the Cuatro Venezolano Scale Harmonizer work?
The Venezuelan cuatro is a four-string instrument with re-entrant tuning: A-D-F#-B (ADF#B). The first string sounds lower than the second, giving it its characteristic bright timbre.
Select a root note and a scale to see all diatonic chords — triads and seventh chords — with chord diagrams for every position on the cuatro fretboard.
Use the interactive fretboard diagram to explore the full scale. Adjust tuning and fret range with the controls below.
