Major Scales: How to Use the Most Important Music Scale

Major scales are an essential building block of all western music. It’s one of the most commonly used musical scales.

While sitting down and practicing the major scale isn’t anyone’s idea of fun, the payoff in the future is rewarding.

By knowing your major scales inside and out, you’ll be able to navigate through all aspects of music theory.

In this article I’ll explain what major scales are, and how you can begin to understand them and use them in your music.

What is the major scale?

The major scale is a seven note scale that consists of a series of whole steps and half steps. The half steps exist between the third and fourth, and seventh and eighth scale degrees.

Another name for the major scale is the diatonic scale. This simply means that the half steps in the scale are spread out as much as possible.



If this sounds confusing, don’t worry! We’re going to break down all the whole steps, half steps and scale degrees in this article.

Let’s get started.

How to build major scales

Looking at the piano is the easiest way to begin understanding the major scale.

If you look at all the white keys on the piano, you’re looking at the C major scale.

The C major scale starts on the white key that comes before the two black keys. This is the first scale degree.

Before we start building the major scale, it’s important for you to know about whole steps and half steps.

One half step is the distance from one note directly to the next one. One whole step is equal to two half steps.

half step and whole step

Now look at the piano. Find a C, and use the following formula to play a C major scale: whole step, whole step, half step, whole step, whole step, whole step, half step.

As you play the scale according to the whole steps and half steps, you’ll also be playing each scale degree from one to seven.

Congratulations! You just played a C major scale. This scale tells you the musical key of C major: no sharps or flats.

Building major scales in other keys

You’ll be able to build a scale starting on any note if you can do it in the key of C major.

When you build major scales in other keys, you’ll start to use the black keys on the piano to fit the major scale formula.

Let’s take a look at the major scale in D major.

Start on D, and use the major scale formula
D whole step to E, whole step to F#, half step to G, whole step to A, whole step to B, whole step to C#, half step to D.

You’ll also notice that the key signature of D major is F# and C#.

This might take a bit to get used to once you start practicing it. You’ll begin to get more comfortable with it as time passes.

After a while you’ll feel it start to become more natural. Applying this information to other areas of music will come quicker and easier to you.

Don’t be afraid to take this formula through the circle of fifths and practice every musical key.

Modes of the major scale

The major scale is also used to build the musical modes. The modes contain the relative minor scale, as well as other frequently used scales.


The modes are all based on the major scale formula.

The modes are all based on the major scale formula.

We call the major scale the Ionian mode, because it starts on the first scale degree. The other six scale degrees in the major scale will give you different modes.

For example, starting the C major scale on the second note D, will give you D Dorian mode: D E F G A B C D.

Continue this pattern by starting the C major scale on any note. This will give you different modes of the major scale, and you’ll start to hear the different tonal qualities as you play them.

Major scales in music

The major scale is considered the basic scale in western music. It’s the bright, stable sound we associate with happy-sounding music.


The major scale is the backbone of functional harmony in music. Remember the tone-semitone pattern I talked about before?

The position of the semitone intervals is what produces the sense of tension and release in progressions of chords built with the notes in the major scale.

That might sound a bit theoretical, but it’s the reason why the major scale can be found absolutely everywhere in music.

With such a fundamental scale, it’s pretty hard to say how best to use it. The best advice is to follow your ears and let your own creativity be your guide.

It’s major for a reason

Don’t forget the major scale in your practice routine. Practice it in all 12 keys. Use it to create new melodies and harmony.

Once this scale you have this scale in your ears, you’ll be a natural when you go to create your next song.
