Banjo tuning notes
The five-string open-G preset is G4, D3, G3, B3, D4. The short fifth string is the high G4 drone; the four full-length strings run D3, G3, B3, D4.
| Target | Note | Frequency |
|---|---|---|
| 1 | G4 | 392.00 Hz |
| 2 | D3 | 146.83 Hz |
| 3 | G3 | 196.00 Hz |
| 4 | B3 | 246.94 Hz |
| 5 | D4 | 293.66 Hz |
Targets are listed in preset order. Frequencies above use A4 = 440 Hz; changing Reference A4 adjusts the live tuner targets.
How to tune your banjo
Check the short drone string separately, then pluck each full-length string. Keep the remaining strings muted so the banjo’s resonant head does not confuse the pitch reading.
Does this banjo tuner work for tenor banjo or double C?
Choose Chromatic for tenor, plectrum, double-C, or other banjo tunings. The preset is specifically five-string open G.
What do flat, sharp, and cents mean?
Flat means your pitch is below the target; sharp means it is above it. A cent is one hundredth of a semitone. Move toward 0 cents using small adjustments. For strings, tighten to raise pitch and loosen to lower it.
Can I change the reference pitch?
Reference A4 defaults to 440 Hz and accepts 400–480 Hz. Match your ensemble’s reference before tuning. The selected preset keeps its note names while its target frequencies adjust.
