Guitar Tuning Guide
Standard Tuning (E-A-D-G-B-E)
Standard tuning is used in most guitar music. From lowest to highest, the strings are tuned to E2 (82.41 Hz), A2 (110 Hz), D3 (146.83 Hz), G3 (196 Hz), B3 (246.94 Hz), and E4 (329.63 Hz). This tuning provides the widest range and works for most musical styles.
Popular Alternate Tunings
| Tuning | Notes (Low to High) | Best For |
|---|---|---|
| Drop D | D-A-D-G-B-E | Rock, metal, easier power chords |
| DADGAD | D-A-D-G-A-D | Celtic, folk, open chord voicings |
| Open G | D-G-D-G-B-D | Blues, slide guitar, Rolling Stones style |
| Half Step Down | Eb-Ab-Db-Gb-Bb-Eb | Easier on vocals, warmer tone |
How to Get Accurate Tuning
- Tune in a quiet environment – Background noise can interfere with pitch detection
- Pluck strings individually – Let each note ring clearly before adjusting
- Use harmonics for fine-tuning – 12th fret harmonics help verify tuning accuracy
- Stretch new strings – New strings go out of tune quickly; pull and retune several times
- Check tuning after playing – Temperature changes and playing can affect tuning stability
When Your Guitar Won't Stay in Tune
If your guitar constantly goes out of tune, check these common issues:
- Worn or old strings need replacement
- Tuning pegs may be loose and need tightening
- Nut slots might be too wide or binding
- Intonation needs adjustment at the bridge
- Temperature and humidity changes affect wood and string tension
Drop D Tuning Tips
Drop D is the most common alternate tuning. Only the low E string changes to D (one whole step down). This creates a heavier sound and makes power chords playable with one finger. To tune: play the open D string (4th string), then match your low E string to sound one octave lower.
