B Tuning (F#BD#G#) 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.
Left open, the strings together spell B6. That is a by-product of how the intervals are laid out rather than the point of the tuning, but it does mean some chords need very few fingers here. See B6 shapes in this tuning →
