Minor scales have a dark and mysterious sound that is used to create tension and emotion in music. They’re essential scales to learn for composers and musicians, but they can be a bit confusing as there are three different types.
In this post, we’re going to be exploring the natural, melodic, and harmonic forms of B-Flat minor scale. So, if you’re ready to dive into the key of B-Flat minor, let’s get started!
Table of Contents
B-Flat Natural Minor Scale
The first form of B-Flat minor that we will look at is the natural minor scale.
It’s made up of seven notes starting on Bb (which is known as the keynote). It then follows the natural minor scale formula of whole and half steps.
This gives us the notes: Bb C Db Eb F Gb Ab
As you can see, it has five flat notes: Bb, Eb, Ab, Db and Gb
B-Flat Natural Minor Scale in the Treble Clef
Here are all the notes of B-Flat natural minor scale in the treble clef, ascending and descending.
B-Flat Natural Minor Scale in the Bass Clef
Next up, we have B-Flat natural minor scale in the bass clef, ascending and descending.
B-Flat Natural Minor Scale in the Alto Clef
The least common of all the clefs, here we have B-Flat natural minor scale in the Alto clef, ascending and descending.
B-Flat Natural Minor Scale in the Tenor Clef
And finally, here are all the notes of B-Flat natural minor scale in the tenor clef, ascending and descending.
Natural Minor Scale Formula
The natural minor scale, like every other type of scale, is constructed by using a certain combination of intervals between each note.
The formula, using whole steps and half steps, is:
Whole step, half step, whole step, whole step, half step, whole step, whole step.
This is abbreviated toW W H W W W H.
Using the British terminology of tones and semitones, this would be:
Tone, semitone, tone, tone, semitone, tone, tone.
Which gets abbreviated toT S T T S T T.
B-Flat Harmonic Minor Scale
The next form of B-Flat minor scale we’ll look at is the B-Flat harmonic minor, which is slightly different from the natural minor in that it has a raised 7th note.
So, the notes in B-Flat harmonic minor are: Bb C Db Eb F Gb A
Like B-Flat natural minor, it also has a Bb, Eb, Db and Gb but, notice that the seventh note is no longer an Ab but has been raised a half step to A natural.
B-Flat Harmonic Minor Scale in the Treble Clef
First, let’s look at B-Flat harmonic minor scale in the treble clef, ascending and descending.
B-Flat Harmonic Minor Scale in the Bass Clef
Next, we have B-Flat harmonic minor ascending and descending in the bass clef.
B-Flat Harmonic Minor Scale in the Alto Clef
The least common of all the clefs, here we have B-Flat harmonic minor ascending and descending in the alto clef.
B-Flat Harmonic Minor Scale in the Tenor Clef
And now we have B-Flat harmonic minor in the tenor clef, ascending and descending.
Hamonic Minor Scale Formula
The natural minor scale, like every other type of scale, is constructed by using a certain combination of intervals between each note.
The formula, using whole steps and half steps, is:
Whole step, half step, whole step, whole step, half step, whole and a half step, half step.
This is abbreviated toW H W W H WH H.
Using the British terminology of tones and semitones, this would be:
Tone, semitone, tone, tone, semitone, tone and a semitone, semitone.
Which gets abbreviated toT S T T S TS S.
B-Flat Melodic Minor Scale
And the last type of minor scale we’ll look at is B-Flat melodic minor scale. This one is a bit different from the others, though.
When it’s ascending, it’s different from the natural in that its 6th and 7th notes are raised.
This gives us the notes: Bb C Db Eb F G A
But, when descending, the 6th and 7th notes are flattened.
This means that it’s the same as the natural minor scale when descending, giving us the notes: Ab Gb F Eb Db C Bb
B-Flat Melodic Minor Scale in the Treble Clef
Let’s take a look at B-Flat melodic minor scale in the treble clef, ascending and descending.
B-Flat Minor Scale in the Bass Clef
Next up, let’s take a look at B-Flat melodic minor scale ascending and descending in the bass clef.
B-Flat Melodic Minor Scale in the Alto Clef
Now we have B-Flat melodic minor scale in the alto clef, ascending and descending.
B-Flat Melodic Minor Scale in the Tenor Clef
And here’s B-Flat melodic minor scale in the tenor clef, ascending and descending.
What is the Key Signature of B-Flat Minor?
To make playing in a certain key easier for the musician to read, we can use a key signature.
This helps us know to play certain notes sharp or flat without having to read an accidental each time.
B-Flat minor has the same key signature as Db major, which has five flats in its key signature: Bb, Eb. Ab, Db and Gb
Here’s the key signature for B-Flat minor in the treble, alto, tenor, and bass clefs.
What is the Relative Major Scale of B-Flat Minor?
Every minor scale has a relative major scale, and every major one has a relative minor one. But what is the relative major scale of B-Flat minor?
The relative major scale of Bb minor is Db major.
Here is Db major scale, which uses all the same notes as B-Flat natural minor but starts on Db, which is its keynote: Db Eb F Gb Ab Bb C
But how do we know that Db major is the relative major scale of B-Flat minor?
Well, to work out the relative major key of a minor one, all we have to do is go up three half steps (semitones).
So from B-Flat, we go up one half step to B, a second half step to C, and a third half step to Db: Bb > B > C > Db
