Learning about A major scale? In this post, we’ve put together a complete guide to everything you need to know when learning about the scale.
We’ll be looking at the notes of A major scale, what it looks like in the treble, bass, alto, and tenor clefs, the degrees of the scale, its key signature, and lots more. Let’s get started.
Notes in A Major Scale
The A major scale is made up of seven notes starting on A (which is known as the keynote). It then follows the major scale formula of whole and half steps.
Those notes are: A B C# D E F# G#
As you can see, it has three sharp notes: F#, C# and G#.
A Major in the Treble Clef
Here are all the notes of A major scale in the treble clef, ascending and descending.
A Major in the Bass Clef
Next, we have all the notes of A major scale in the bass clef, ascending and descending.
A Major in the Alto Clef
Here are all the notes of A major scale in the alto clef, ascending and descending.
A Major in the Tenor Clef
And last of the clefs, here are all the notes of A major scale in the tenor clef, ascending and descending.
A Major Scale Formula
Like every major scale, A major follows a certain formula of whole and half steps which is:
Whole step, whole step, half step, whole step, whole step, whole step, half step.
This is abbreviated to W W H W W W H.
Using the British terminology of tones and semitones, this would be:
Tone, tone, semitone, tone, tone, tone, semitone
Which gets abbreviated to T T S T T T S.
A Major Scale Degrees and Technical Names
In music theory, we can refer to each note of a scale by numbers which we call the degrees of a scale.
The first note is the 1st degree, the second is the 2nd degree, the third note is the 3rd degree, etc.
But, each scale degree has another name which is called the technical names of the scale.
Here are the technical names and scale degrees of A major scale.
- 1st – Tonic – A
- 2nd – Supertonic – B
- 3rd – Mediant – C#
- 4th – Subdominant – D
- 5th – Dominant – E
- 6th – Submediant – F#
- 7th – Leading tone – G#
A Major Key Signature
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.
A major has three sharps in its key signature: F#, C# and G#.
Here’s the key signature for A major in the treble, alto, tenor, and bass clefs.
What is the Relative Minor of A Major?
Every major key has a relative minor key. What makes them related is that they both share the same key signature.
The relative minor key of A major is F-Sharp Minor.
Here is F-Sharp natural minor scale, which uses all the same notes as A major but starts on F-Sharp, which is its keynote: F# G# A B C# D E
But how do we know that F-Sharp minor is the relative minor of A major? Well, to work out the relative minor key of a major one, all we have to do is go down three half steps (semitones).
So from A, we go down one half step to G#, a second half step to G, and a third half step to F#: A > G# > G > F#
That’s it for the scale of A major! We hope it helped make a bit more sense of everything.
