How this tuning changes the guitar

The open strings spell D-G-D-G-B-D, forming a G major chord with the fifth in the bass. Relative to standard tuning, the first, fifth, and sixth strings are lowered to D, G, and D.

Fretboard and chord implications

A straight barre moves the major harmony, while strings 5 through 1 contain the compact G-D-G-B-D layout often used for rhythm and slide. The low sixth-string D can function as a fifth or be omitted when a root-position bass is needed.

Common uses

Practice this tuning

  1. Tune from low to high as D G D G B D, then play each open string while saying its note name and string number aloud.
  2. Map G roots on strings 5 and 3, then connect them with B thirds and D fifths in three neighboring positions.
  3. Play a G-C-D progression with full barres, then create a second version using only strings 5 through 1 and open-string drones.
