Sawmill / Mountain Modal (gDGCD) is re-entrant: the strings do not rise steadily in pitch, so the string nearest your thumb is not the lowest note available. That is deliberate, and it is a large part of why the instrument sounds the way it does.

Strummed open, with nothing fretted, the strings spell Gsus4. That is what makes a tuning like this useful for slide playing and drones – a full chord is one straight barre away at any fret. See Gsus4 shapes in this tuning →

Sawmill, also called mountain modal or G modal, raises one string of Open G so the open chord becomes suspended rather than major. The banjo stops sounding a definite major chord and starts sounding modal – which is what the older Appalachian repertoire wants.

Tunes like "Shady Grove" and "Cluck Old Hen" live here. It is the tuning that most clearly separates old-time banjo from bluegrass banjo.
