Major Scale Explained: Formula and Notes in All 12 Keys
Share
The major scale is the starting point for almost all music theory. Know this one scale and chords, minor keys, modes and the circle of fifths suddenly make a lot more sense. Best part: you build it with one simple pattern that is the same in every key.
In this guide you will learn how the major scale is built, the notes in all 12 keys, how many sharps or flats each key has, and how to use it for a melody in your beat or a hook you sing yourself.
What is the major scale?
A scale is a row of notes you pull your melodies and chords from. The major scale has seven different notes. The eighth note is the root again, one octave higher. Major sounds bright and open, which is why it is the foundation of so much pop, house, afro, gospel and summery hooks.
What makes a scale major is not which notes you pick, but the distance between them. For that we use two step sizes:
- Half step (H): one key up on the piano, black keys included. E to F is a half step.
- Whole step (W): two keys up. C to D is a whole step, because C# sits in between.
The formula: W, W, H, W, W, W, H
Every major scale follows exactly the same pattern from the root:
Whole, whole, half, whole, whole, whole, half.
In C major it looks like this:
- C to D: whole step
- D to E: whole step
- E to F: half step
- F to G: whole step
- G to A: whole step
- A to B: whole step
- B to C: half step
That gives you C, D, E, F, G, A, B: white keys only. That is why C major is where everyone starts. Start on a different note and you need black keys to keep the pattern intact. Start on G, for example, and the seventh note has to be F# instead of F, otherwise the last half step does not work out.
Easy way to remember it: think of two groups. W, W, H and then W, W, W, H, with one whole step joining them. Want to dig deeper into the distance between notes? Read music intervals explained.
The major scale in all 12 keys
Below are the notes of every major scale, with the number of sharps (#) or flats (b). The order of the table is not random: each row moves up a fifth, and every step adds one sharp or removes one flat. That is exactly how the circle of fifths works.
| Key | Notes | Key signature |
|---|---|---|
| C major | C, D, E, F, G, A, B | none |
| G major | G, A, B, C, D, E, F# | 1 sharp |
| D major | D, E, F#, G, A, B, C# | 2 sharps |
| A major | A, B, C#, D, E, F#, G# | 3 sharps |
| E major | E, F#, G#, A, B, C#, D# | 4 sharps |
| B major | B, C#, D#, E, F#, G#, A# | 5 sharps |
| F# major | F#, G#, A#, B, C#, D#, E# | 6 sharps |
| Db major | Db, Eb, F, Gb, Ab, Bb, C | 5 flats |
| Ab major | Ab, Bb, C, Db, Eb, F, G | 4 flats |
| Eb major | Eb, F, G, Ab, Bb, C, D | 3 flats |
| Bb major | Bb, C, D, Eb, F, G, A | 2 flats |
| F major | F, G, A, Bb, C, D, E | 1 flat |
Why is there an E# in F# major? A scale uses every letter exactly once. In F# major the seventh note is the same key as F, but since F# is already taken, you write it as E#. In your DAW it makes no difference: it is the same key. F# major is also known as Gb major, with exactly the same keys.
Db or C#? Same key again. Producers and DAWs use both names. Beat Lab or your DAW might say C# major while a chord book says Db major. Same notes, different name.
Sharps and flats: which ones, and in what order?
Sharps and flats are always added in a fixed order. That is handy if you read sheet music or just want to know quickly which black keys you need.
- Sharps: F#, C#, G#, D#, A#, E#, B#. G major only has the first one (F#), D major the first two (F# and C#), and so on.
- Flats: Bb, Eb, Ab, Db, Gb, Cb, Fb. F major only has Bb, Bb major has Bb and Eb, and so on. It is the order of the sharps, just backwards.
Two tricks to name the key from the key signature:
- With sharps: take the last sharp and go up a half step. Three sharps (F#, C#, G#)? A half step above G# is A, so A major.
- With flats: the second to last flat is the key. Three flats (Bb, Eb, Ab)? The second to last is Eb, so Eb major. This does not work with one flat: that is F major.
The seven scale degrees: names and chords
Every note of the scale has a number (degree) and a name. You mostly hear the names in music class. As a producer you will use the numbers more, for example in chord progressions like I, V, vi, IV.
| Degree | Name | In C | Chord |
|---|---|---|---|
| 1 | Tonic (root) | C | C (I) |
| 2 | Supertonic | D | Dm (ii) |
| 3 | Mediant | E | Em (iii) |
| 4 | Subdominant | F | F (IV) |
| 5 | Dominant | G | G (V) |
| 6 | Submediant | A | Am (vi) |
| 7 | Leading tone | B | Bdim (vii°) |
The chord pattern is the same in every major key: major, minor, minor, major, major, minor, diminished. So once you know the scale, you also know the seven chords that naturally fit with it. The chords by key page has them written out for every key, and Roman numeral chords explained shows you how to read progressions like I, V, vi, IV.
More of a singer? You might know the major scale as do, re, mi, fa, sol, la, ti, do. That is exactly the same scale, with do on the root.
Major and its relative minor
Start on the sixth note of C major (A) and play the same white keys, and you get A minor. That is called the relative minor: same notes, different home. Every major key has one, three half steps lower. G major goes with E minor, F major with D minor.
That makes this table useful for minor key beats too. If your beat is in E minor, use the notes of G major, just let your melody land on E. All pairs are listed in the relative minor chart. Want to hear the difference clearly first? Read major vs minor explained.
How to use the major scale in your beat
- Check the key. Working with a sample, loop or beat you already have? Drop it into the free Beat Lab to see the BPM and key. If Beat Lab says "D Maj", grab the D major row from the table.
- Lay down chords. Pick two to four chords from the key. With the free chord progression generator you choose a mood, set it to major, listen in your browser and download the MIDI for your DAW.
- Turn on the scale in your piano roll. Most DAWs can highlight the notes of a scale in the piano roll. Pick the root and "major", and you see right away which keys belong to the scale.
- Land on chord tones. On the first beat of a bar, a note from the chord underneath sounds strongest. In between, move freely through the scale.
- Watch the 4th and 7th notes. In C those are F and B. They sit a half step away from another scale note, so they create the most tension. Use them as passing notes, or leave them out and play pentatonic. Here is how that works: the pentatonic scale explained.
- Repeat and vary. A short one or two bar phrase that comes back sticks better than a long melody. More tips in how to make a melody for your beat.
For rappers and singers: hooks and Auto-Tune
Writing a melodic hook over a beat in a major key? It helps to know which seven notes are "safe". Hum your hook, find the notes on your keyboard or in a piano app and check whether they are in the row for your key. If you are just off somewhere, you know straight away which way to move.
If you use Auto-Tune or another pitch correction plugin, you set the key and scale there. Pick the root of the beat and "Major". If the beat is in minor, choose the minor of that root, or its relative major: those are the same notes. If the hook sits too high or too low for your voice, transpose the beat to a key that fits you better.
Common mistakes
- Making every step a whole step. There is a half step between the 3rd and 4th notes and between the 7th and 8th. Skip those and you no longer have a major scale.
- Counting keys without the black keys. A whole step is two keys, black keys included. Between E and F and between B and C there is no black key, so one step there is already a half step.
- The wrong root. C major and A minor share the same notes. If your melody never seems to get "home", check where it lands.
- Running up and down the scale and calling it a melody. A scale is your toolbox, not a song. Rhythm, repetition and silence turn it into a melody.

FAQ
How many notes are in a major scale?
Seven different notes. The eighth note is the root one octave higher, which is why you often see the scale written out with eight notes.
What is the major scale formula?
Whole, whole, half, whole, whole, whole, half. Short: W, W, H, W, W, W, H. The pattern is the same in every key.
Which major scale has no sharps or flats?
Only C major. It uses the white keys only: C, D, E, F, G, A, B.
How many sharps are in D major?
Two: F# and C#. The notes are D, E, F#, G, A, B, C#.
How many flats are in Bb major?
Two: Bb and Eb. The notes are Bb, C, D, Eb, F, G, A.
What is the difference between the major and minor scale?
Compared with major on the same root, the natural minor scale has a lowered 3rd, 6th and 7th. That makes it sound darker. The natural minor formula is W, H, W, W, H, W, W.
