B flat Harmonic Minor Intervals
The harmonic minor scale is the same as the natural minor, except for a raised 7th degree by a semitone. In terms of intervals, this changes the major 2nd interval between 6th and 7th notes to an augmented 2nd.
You can see the intervals in the B flat Harmonic Minor scale below. It’s worth remembering that these intervals will be the same for all harmonic minor scales.
The Harmonic Minor Formula
The harmonic minor scale is based on the natural minor scale but with a sharpened 7th degree. The tone and semitone pattern of the scale is shown below.

B flat Harmonic Minor Modes
The natural minor scale is the same as the Aeolian mode, so this means that if we raise the 7th of the Aeolian we will get the harmonic minor scale. This is written as Aeolian #7. The great thing about the modes is that they all link together, A Aeolian has the same notes as B Locrian, except that B Locrian starts on a B. And C Ionian has the same notes too, except it starts and ends on a C. If the is news to you, check out our guide to modes for more detail.
As the modes link together we can create modes for B flat Harmonic Minor using this approach. The mode names and notes are set out below.
