About the B♭ Major Scale

The B♭ Major scale follows the major scale formula (W–W–H–W–W–W–H), producing seven diatonic chords. Major chords (I, IV, V) provide brightness and resolution; minor chords (ii, iii, vi) add color and tension; the diminished chord (vii°) creates strong pull toward the tonic.
