Change three strings from standard
From EADGBE, lower the sixth string E2 to D2, lower the fifth string A2 to G2, keep D3, G3 and B3, then lower the first string E4 to D4. The resulting D2 G2 D3 G3 B3 D4 notes spell a G major harmony across the open strings.
- Lower strings 6, 5 and 1
- Keep strings 4, 3 and 2
- Use the preset to avoid octave mistakes
Recheck before playing with a slide
Several lowered strings can pull the other strings slightly sharp, so repeat the tuning pass after a few strums. Open G supports movable major shapes and slide playing, but accurate intonation still depends on stable open-string tuning. GuitarTool shows cents, frequency, input strength and stability together.
- Make a second pass after strumming
- Watch stability before accepting a note
- A4 calibration supports 430–446 Hz
