Played open, the strings sound C-G – from C4 at the bottom to G4 at the top, a span of 7 semitones. Step by step across the neck the intervals are a fifth, and that is what decides how chord shapes fall under the hand.
Strummed open, the strings spell C5 – root and fifth with no third, so the tuning stays neutral between major and minor.
