Key of B♭ major
The key of B♭ major has two flats — B♭ and E♭. Its scale runs B♭ C D E♭ F G A, and building a triad on each of those seven notes — stacking thirds from the scale itself — produces the key's seven chords.
That gives three major chords, three minor chords and one diminished chord. The majors — B♭ (I), E♭ (IV) and F (V) — are the workhorses that carry most songs in the key; the minors Cm (ii), Dm (iii) and Gm (vi) supply the softer colors, and A° (vii°) appears mostly as a passing chord.
Relative minor: G minor — the same seven chords, with Gm as home base.
