B-flat minor is a minor scale based on B♭, consisting of the pitches B♭, C, D♭, E♭, F, G♭, and A♭. Its key signature has five flats. Its relative major is D-flat major and its parallel major is B-flat major. Its enharmonic equivalent, A-sharp minor, which would contain seven sharps, is not normally used.

The B-flat natural minor scale is:

Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The B-flat harmonic minor and melodic minor scales are:

${ \omit Score.TimeSignature \relative c' { \key bes \minor \time 7/4 bes^"Harmonic minor scale" c des es f ges a bes a ges f es des c bes2 } }$

${ \omit Score.TimeSignature \relative c' { \key bes \minor \time 7/4 bes^"Melodic minor scale (ascending and descending)" c des es f g a bes aes! ges! f es des c bes2 } }$

Characteristics

B-flat minor is traditionally a 'dark' key.^[1]

The old valveless horn was barely capable of playing in B-flat minor: the only example found in 18th-century music is a modulation that occurs in the first minuet of Franz Krommer's Concertino in D major, Op. 80.^[2]
