Guitar tunings explained
A tuning names the open pitch of each string. Check both the string order and octave where supplied, then tune the instrument to match the selected arrangement.
Read tuning from low string to high string
Most guitar tuning labels are written from the thickest string to the thinnest. Standard six-string tuning is E–A–D–G–B–E in that order. The octave number distinguishes pitch: standard tuning is E2–A2–D3–G3–B3–E4 in scientific pitch notation. A label without octave numbers gives note names but less pitch detail.
Standard: E2 A2 D3 G3 B3 E4 Drop D: D2 A2 D3 G3 B3 E4 7-string standard: B1 E2 A2 D3 G3 B3 E4
- Drop D changes only the lowest string, from E2 down to D2.
- A seven-string guitar adds a lower string; do not read that tuning as though it had six strings.
- Player data may store strings in a different internal order. Follow the displayed tuning label and the arrangement instructions rather than inferring order from software internals.
Drop D and DADGAD
Drop D lowers only the sixth string from E to D. It can make low D notes and some power-chord shapes easier to reach. Browse arrangements in the Drop D collection and check the tuning for the version you choose.
DADGAD changes several strings and creates open-string sonorities used in many styles. Standard-tuning chord shapes will not keep their usual pitch relationships.
- Retune gradually and check each string again after the others settle.
- Use an electronic tuner or a reliable reference pitch.
- Recheck the tuning whenever you switch arrangements.
Open tunings
An open tuning forms a chord when the open strings are strummed. Open G and Open D are common examples. Labels can omit octaves, and instruments may use different string counts, so use the arrangement’s complete tuning information when it is available.
Frequently asked questions
- What is standard guitar tuning?
- From the lowest string to the highest, standard tuning is E–A–D–G–B–E. It is the reference point for most tabs and chord diagrams.
- What is Drop D tuning?
- Drop D lowers only the sixth string from E to D. It adds a low tonic note and lets you play power chords with one finger, which suits heavier riffs and wider fingerstyle bass lines.
- Do I need to retune for every tab?
- Check the tuning printed for the selected arrangement. Two versions of one song can use different tunings.
- What is an open tuning?
- An open tuning forms a complete chord when you strum all strings without fretting anything. Open G and Open D are common for slide guitar and droning accompaniment.
