Brazilian cavaquinho tuning
The common Brazilian setup is D4 G4 B4 D5, with a high D completing the compact open voicing. The Portuguese natural setup raises that last string to E5.
Because GDAE uses a wider range and different intervals, confirm that the installed string set is suitable before choosing that preset.
Four clear steps
How to tune accurately
- 1Start with D4 and use a clean single-string pluck.
- 2Continue through G4 and B4 while muting sympathetic strings.
- 3Finish at D5 for Brazilian or E5 for Portuguese tuning.
- 4Recheck all four strings after playing a few chords.
Reference: A4 = 440 Hz
