Minor Key Chords
Let’s find all the chords for the key of A sharp minor on the piano. We can use these chords to create chord progressions and play creatively in that key!
How to Find Chords for the Key of A Sharp Minor
To find chords for the key of A sharp minor, we’ll first need to build an A sharp minor scale.
There are different kinds of minor scales, so let’s start with the natural minor scale. Natural minor scales each have a relative major scale on the piano. This means these two scales use the same notes to build their scales, but start and end on different notes.
A sharp minor is relative to C sharp major, so these two scales use the same notes to build their scales, but start and end on different notes. Since the notes in a scale are used to build the chords for that key, these two scales also share the same chords, just in a different order.
Here are the notes for an A sharp natural minor scale:
A♯ – B♯ – C♯ – D♯ – E♯ – F♯ – G♯ – A♯
Now we’ll start building a “1 – 3 – 5” chord off each note of the scale, using only the notes of the scale to build the chords.
We’ll start on A♯ and build a “1 – 3 – 5” chord, using only the notes of the scale. When we do, we get: A♯ – C♯ – E♯
Then we’ll start on B♯ and build another “1 – 3 – 5” chord, using the notes of the scale. When we do, we get: B♯ – D♯ – F♯
Next we’ll start on C♯ and build another “1 – 3 – 5” chord, using the notes of the scale. When we do, we get: C♯ – E♯ – G♯
We can continue following this pattern, building a “1 – 3 – 5” chord (also called a “triad”) off each note of the scale, and using only the notes of the scale to build the chords.
Chords for the Key of A Sharp Minor
Here are the chords for the key of A sharp minor:
A♯ – C♯ – E♯ = A♯ minor chord
B♯ – D♯ – F♯ = B♯ diminished chord
C♯ – E♯ – G♯ = C♯ major chord
D♯ – F♯ – A♯ = D♯ minor chord
E♯ – G♯ – B♯ = E♯ minor chord
F♯ – A♯ – C♯ = F♯ major chord
G♯ – B♯ – D♯ = G♯ major chord
How Do We Label the Chords?
You may be wondering how we can tell the difference between major, minor, and diminished chords. It all depends on the intervals used to build the chords (learn about intervals here).
But to summarize, there are actually four types of “1 – 3 – 5” chords, or triads:
Major chords are built with the first, third and fifth notes of the matching major scale.
Minor chords are built with the first, third and fifth notes of the matching major scale, but the middle note is lowered 1/2 step.
Augmented chords are built with the first, third and fifth notes of the matching major scale, but the third and fifth notes are raised 1/2 step.
Diminished chords are built with the first, third and fifth notes of the matching major scale, but the third and fifth notes are lowered 1/2 step.
When we build a “1 – 3 – 5” chord off each note of a natural minor scale, using only the notes of the scale to build the chords, we’ll always get these chord types in this order:
Minor
Diminished
Major
Minor
Minor
Major
Major
We can use this pattern to find the chords for other minor keys!
Primary Chords for A Sharp Minor
Each minor key has three “primary” chords built off the first, fourth and fifth notes of the scale. Primary chords are used frequently in songs.
The primary chords for the key of A sharp minor are:
A♯ minor
D♯ minor
E♯ minor
Enharmonic Keys
Some keys are considered “enharmonic”. This means they use the same notes on the piano, but can go by two different names.
The key of A sharp minor is enharmonic with B flat minor, because these two keys use the same notes on the piano, but are labeled differently.
There are six total enharmonic minor keys:
A sharp minor and B flat minor
D sharp minor and E flat minor
G sharp minor and A flat minor
How to Find Chords for A Sharp Minor Using the Harmonic Minor Scale
Now let’s find chords for A sharp minor using the harmonic minor scale.
Harmonic minor scales are similar to natural minor scales, except the seventh note is raised 1/2 step.
Here are the notes for an A sharp harmonic minor scale:
A♯ – B♯ – C♯ – D♯ – E♯ – F♯ – G♯♯ – A♯
If you’re wondering why we label one of the notes G♯♯, it’s because scales must progress in alphabetical order. Since the note before the G♯♯ is an F♯, the note that follows must be some sort of G.
Now we’ll build a “1 – 3 – 5” chord off each note of the harmonic minor scale, using only the notes of the scale to build the chords as before.
Chords for A Sharp Minor Using the Harmonic Minor Scale
Here are the chords for A sharp minor when we use the harmonic minor scale:
A♯ – C♯ – E♯ = A♯ minor chord
B♯ – D♯ – F♯ = B♯ diminished chord
C♯ – E♯ – G♯♯ = C♯ augmented chord
D♯ – F♯ – A♯ = D♯ minor chord
E♯ – G♯♯ – B♯ = E♯ major chord
F♯ – A♯ – C♯ = F♯ major chord
G♯♯ – B♯ – D♯ = G♯♯ diminished chord
Labeling the Chords
When we build a “1 – 3 – 5” chord off each note of a harmonic minor scale, we’ll always get these chord types in this order:
Minor
Diminished
Augmented
Minor
Major
Major
Diminished
Primary Chords for A Sharp Minor Using the Harmonic Minor Scale
The primary chords for A sharp minor, using the harmonic minor scale to build the chords, are:
A♯ minor
D♯ minor
E♯ major
When we use the harmonic minor scale instead of the natural minor scale to build the chords, the third primary chord becomes major instead of minor, creating some nice contrast.
