## Solution - 2 parts

### 1. B-flat harmonic minor scale

This step shows the ascending B-flat harmonic minor scale on the piano, treble clef and bass clef. It also shows the scale degree names for all 8 notes.

The B-flat harmonic minor scale has 4 flats.

This harmonic minor scale is based on the natural minor scale with the same key / tonic note - Bb natural minor scale.

Since the natural minor key is itself on the Circle of 5ths - Bb minor on circle of 5ths, this means that this is a commonly used harmonic minor scale key.

This scale sounds the same as the A# harmonic minor scale, which is also a commonly used scale. The same notes are played in the same order in each scale - they sound identical. Only the names of the individual notes are different.

B-flat harmonic minor scale note names
Note no.Note intervalNote name
1tonicThe 1st note of the B-flat harmonic minor scale is Bb
2Bb-maj-2ndThe 2nd note of the B-flat harmonic minor scale is C
3Bb-min-3rdThe 3rd note of the B-flat harmonic minor scale is Db
4Bb-perf-4thThe 4th note of the B-flat harmonic minor scale is Eb
5Bb-perf-5thThe 5th note of the B-flat harmonic minor scale is F
6Bb-min-6thThe 6th note of the B-flat harmonic minor scale is Gb
7Bb-maj-7thThe 7th note of the B-flat harmonic minor scale is A
8Bb-perf-8thThe 8th note of the B-flat harmonic minor scale is Bb

Middle C (midi note 60) is shown with an orange line under the 2nd note on the piano diagram.

These note names are shown below on the treble clef followed by the bass clef.

The stave diagrams above show the scale notes without a key signature, with the sharp / flat adjustments inserted before each note on the staff.

For the key signature of this scale, showing the symbols grouped correctly next to the bass or treble clef symbol at the beginning, have a look at the Bb harmonic minor key signature.

B-flat harmonic minor scale degrees
Note no.Degree name
1Bb is the tonic of the B-flat harmonic minor scale
2C is the supertonic of the B-flat harmonic minor scale
3Db is the mediant of the B-flat harmonic minor scale
4Eb is the subdominant of the B-flat harmonic minor scale
5F is the dominant of the B-flat harmonic minor scale
6Gb is the submediant of the B-flat harmonic minor scale
7A is the leading tone of the B-flat harmonic minor scale
8Bb is the octave of the B-flat harmonic minor scale

The difference between the B-flat harmonic minor scale and the Bb natural minor scale is that the 7th note position of the minor scale is raised by one half-tone / semitone.

So whereas the Bb natural minor scale has note Ab for the 7th note, this note is raised to arrive at note A for this harmonic minor scale.

This step shows the descending B-flat harmonic minor scale on the piano, treble clef and bass clef.

## Lesson steps

### 1. Piano key note names

This step shows the white and black note names on a piano keyboard so that the note names are familiar for later steps, and to show that the note names start repeating themselves after 12 notes.

The white keys are named using the alphabetic letters A, B, C, D, E, F, and G, which is a pattern that repeats up the piano keyboard.

Every white or black key could have a flat(b) or sharp(#) accidental name, depending on how that note is used. In a later step, if sharp or flat notes are used, the exact accidental names will be chosen.

The audio files below play every note shown on the piano above, so middle C (marked with an orange line at the bottom) is the 2nd note heard.

### 2. B-flat tonic note and one octave of notes

This step shows an octave of notes in the key of B-flat, to identify the start and end notes of the scale.

The numbered notes are those that might be used when building this note scale.

But since this is a scale in the key of Bb, it is certain that notes 1 and 13 will be used in the scale.

Note 1 is the tonic note - the starting note - Bb, and note 13 is the same note name but one octave higher.

 No. Note 1 2 3 4 5 6 7 8 9 10 11 12 13 Bb B C C# / Db D D# / Eb E F F# / Gb G G# / Ab A Bb

### 3. B-flat harmonic minor scale note interval positions

This step applies the harmonic minor scale note interval pattern starting from B-flat, so that the correct piano keys and note pitches can be identified.

The harmonic minor scale uses the  W-H-W-W-H-W½-H  note counting rule to identify the scale note positions.

To count up a Whole tone, count up by two physical piano keys, either white or black.

To count up a Half-tone (semitone), count up from the last note up by one physical piano key, either white or black.

To count up a tone (whole-tone and a half), count up from the last note by 3 half-tones / semitones - shown as 3 on the piano below.

The tonic note (shown as *) is the starting point and is always the 1st note in the harmonic minor scale.

Again, the final 8th note is the octave note, having the same name as the tonic note.
 No. Note 1 2 3 4 5 6 7 8 Bb C C# / Db D# / Eb F F# / Gb A Bb

What is the difference between the B-flat harmonic minor scale and the Bb natural minor scale ?

The 7th note position (or scale degree) of the minor scale is raised by one half-tone / semitone to arrive at the harmonic minor scale note positions shown above, leaving a noticeably large interval of 3 half-tones / semitones between the 6th and 7th note positions for this scale.

### 4. B-flat harmonic minor scale notes

This step tries to assign note names to the piano keys identified in the previous step, so that they can be written on a note staff in the Solution section.

The 7 unique notes in a scale need to be named such that each letter from A to G is used once only, so each note name is either a natural white name(A.. G) , a sharp(eg. F#) or a flat(eg. Gb).

This is needed to ensure that when it comes to writing the scale notes on a musical staff (eg. a treble clef), there is no possibility of having 2 G-type notes, for example, with one of the notes needing an accidental next to it on the staff (a sharp, flat or natural symbol).

To apply this rule, firstly list the white key names starting from the tonic, which are shown the White column below.

Then list the 7 notes in the scale so far, shown in the next column.

For each of the 7 notes, look across and try to find the White note name in the Scale note name.

If the natural white note can be found in the scale note, the scale note is written in the Match? column.

The 8th note - the octave note, will have the same name as the first note, the tonic note.

For this harmonic minor scale, all notes have a match, and so the Match? column shows the harmonic minor scale note names.

### 5. B-flat harmonic minor scale descending

This step shows the notes when descending the B-flat harmonic minor scale, going from the highest note sound back to the starting note.

For harmonic minor scales, the notes names when descending are just the reverse of the ascending names.

So assuming octave note 8 has been played in the step above, the notes now descend back to the tonic.

 No. Note 1 2 3 4 5 6 7 A Gb F Eb Db C Bb

### 6. B-flat harmonic minor scale degrees

This step shows the B-flat harmonic minor scale degrees - tonic, supertonic, mediant, subdominant, dominant, submediant, leading note / tone, and octave.
In music theory, each note in this scale has what is called a scale degree name, which describes the relationship of that note to the tonic(1st) note.

Scale degree names 1,2,3,4,5,6, and 8 below are always the same for all major and minor scales (ie. 1st note is always tonic, 2nd is supertonic etc.) , but obviously the note names will be different for each scale / key combination.

In the harmonic minor scale, the 7th note is called the leading note or leading tone because the sound of the 7th note feels like it wants to resolve and finish at the octave note, when all scale notes are played in sequence.

It does this because in this scale, the 7th note is only 1 half-tone / semitone away from the 8th note - the octave note. The Bb major scale and Bb melodic minor scale scales share the same property - they both have only one half-tone / semitone between the 7th and 8th notes.

In contrast, the Bb natural minor scale has a whole tone (two half-tones / semitones, two notes on the piano keyboard) between the 7th and 8th notes, and the 7th note does not lean towards the 8th note in the same way. In this case, the 7th note is called the subtonic.
