Played open, the strings sound F-A-C-G-C-E – from F2 at the bottom to E4 at the top, a span of 1 octave and 11 semitones. Step by step across the neck the intervals are a major third, a minor third, a fifth, a fourth, a major third, and that is what decides how chord shapes fall under the hand.

The drop is small enough that a standard set handles it. If the lowest string starts to rattle against the frets, one step up in gauge fixes it.
