The natural minor key signature of the bass or treble clef is used, with the differences between the two scales shown as adjustments next to the note names on the staff, not in the key signature itself.The harmonic minor scale raises the 7th note of the natural minor scale by a half step and has the following scale formula: W – H – W – W – H – W+H – H (Learn how to build minor scales here. B-flat harmonic minor key signature adjustments No

The 7th note of the natural minor scale needs to be raised by one half-tone / semitone, which will result in adjustment action on the existing natural minor note name. This step shows the B-flat harmonic minor key signature on a treble and bass clef, together with a table showing the note adjustments that need to be made relative to the natural minor scale.īelow is a table showing the note name adjustments that describe the difference between this harmonic scale note and the natural minor scale, whose key signature it uses. To understand why the B-flat harmonic minor scale has 4 flats, have a look at the Bb harmonic minor scale page, which shows the music theory rules for identifying the note positions and names for this scale. Now compare this to the next step showing the natural minor scale (specifically the 7th note). However, harmonic minor key signatures use the natural minor key signature of the same key (in this case - Bb natural minor key signature) next to the treble clef, and then the differences between the two scales are shown as adjustments next to the note names on the staff.įirstly, in this step, the harmonic minor scale is shown on a piano keyboard. Chords in natural minor keys follow the pattern, minor diminished major minor minor major major. Just put the correct number of sharp or flat symbols next to the treble clef. The notes of the B flat minor natural scale are: Bb C Db Eb F Gb Ab. This step shows the number of sharps or flats in this harmonic minor scale so that the number of symbols needed for the key signature can be identified.įor the major and natural minor scales, no more information is needed to write the key signature.
