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:


\header { tagline = ##f }
scale = \relative c' { \key bes \minor \omit Score.TimeSignature
  bes^"Natural minor scale" c des es f ges aes bes aes ges f es des c bes2 \clef F \key bes \minor }
\score { { << \cadenzaOn \scale \context NoteNames \scale >> } \layout { } \midi { } }

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:


\header { tagline = ##f }
scale = \relative c' { \key bes \minor \omit Score.TimeSignature
  bes^"Harmonic minor scale" c des es f ges a bes a ges f es des c bes2 }
\score { { << \cadenzaOn \scale \context NoteNames \scale >> } \layout { } \midi { } }

\header { tagline = ##f }
scale = \relative c' { \key bes \minor \omit Score.TimeSignature
  bes^"Melodic minor scale (ascending and descending)" c des es f g a bes aes! ges! f es des c bes2 }
\score { { << \cadenzaOn \scale \context NoteNames \scale >> } \layout { } \midi { } }

Characteristics

[edit]

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]
