B♭ Harmonic minor Scale

– – – – – – –

Summary

B♭ Harmonic minor contains 7 notes: B♭, C, D♭, E♭, F, G♭, A. It has 4 flats: B♭, D♭, E♭, G♭. The step pattern is W–H–W–W–H–W+H–H.

Harmonic minor takes the natural minor scale and raises the 7th note by a half step. This gives it a dramatic, exotic sound with a distinctive "gap" between the 6th and 7th notes that you can instantly recognize.

Theory

Built as 1 - 2 - b3 - 4 - 5 - b6 - 7, harmonic minor differs from natural minor by a single note: the raised 7th. This creates a leading tone that pulls strongly to the tonic, enabling a major V chord to resolve to a minor i chord. The trade-off is a 3-semitone augmented 2nd interval between b6 and 7, which gives the scale its signature classical and Middle Eastern flavor. The tonic chord is a min(maj7).

On the guitar

Learn this scale using 3-notes-per-string shapes or CAGED patterns rooted on the 6th and 5th strings. The augmented 2nd gap between b6 and 7 creates a natural stretch on the fretboard that feels awkward at first but becomes a signature sound. Focus on using this scale over V7 and viio7 chords in minor progressions to heighten tension before resolution.

Advanced

Harmonic minor generates seven modes, each with unique applications. The scale is the backbone of classical minor-key harmony and a favorite of neoclassical shredders. Its augmented 2nd interval can be exploited for dramatic runs and sequences that sound both technical and emotional.
