How the key of B major works
B Major carries five sharps (F#, C#, G#, D# and A#). The scale runs B–C#–D#–E–F#–G#–A#, and stacking every other note of that scale builds the seven chords above — every chord tone comes from those same seven notes.
G# Minor is the relative minor: identical key signature, identical seven chords. A song that treats G#m — the vi chord here — as home base is in G# minor, even though its chord inventory matches this page exactly.
The parallel minor, B Minor, keeps the same root but flattens the third, sixth, and seventh — its signature shifts to two sharps (F# and C#). Borrowing chords across that line is where a lot of songwriting color comes from.
