Major Scales in All 12 Keys

Updated: 2026-10-23

Every major scale has seven different notes and the same pattern of steps between them. Learn that pattern once and you can build the scale on any of the 12 notes. Learn the order of the keys around the circle of fifths and you will know, without looking anything up, that A major has three sharps and E♭ major has three flats.

This guide covers the formula, the circle of fifths, a quick way to work out the key signature, the full list of notes for all 12 keys, and a practice plan for piano and guitar.

The formula: W W H W W W H

On a piano, a half step (H) is the distance from one key to the very next key, black or white. A whole step (W) is two half steps. The major scale is this sequence of steps from the root:

W W H W W W H

Start on C and follow it on the white keys: C to D is a whole step, D to E whole, E to F half (there is no black key between them), F to G whole, G to A whole, A to B whole, B to C half. That gives C D E F G A B C, the only major scale with no sharps or flats.

Now start on G. G to A is W, A to B is W, B to C is H, C to D is W, D to E is W. The next step must be W, but E to F is only a half step, so you need F♯. Then F♯ to G is H. G major is G A B C D E F♯ G: one sharp.

Two rules keep the spelling clean. First, each letter from A to G appears exactly once. That is why F major is F G A B♭ C D E and not F G A A♯ C D E: A is already used, so the 4th note has to be a B of some kind. Second, a major scale uses only sharps or only flats, never both.

On a guitar the formula is visible as fret distances along one string: a whole step is 2 frets and a half step is 1 fret. On the A string, start open and play frets 0, 2, 4, 5, 7, 9, 11, 12. Those are the notes A B C♯ D E F♯ G♯ A: A major, using the steps 2 2 1 2 2 2 1.

The circle of fifths

The 12 major keys can be arranged so each one adds a single sharp or flat to the last. Go up a perfect 5th (7 half steps) from C and you reach G, with one sharp. Up another 5th: D, two sharps. Then A with three, E with four, B with five, F♯ with six and C♯ with seven.

Go the other way, down a 5th (or up a 4th), and you add flats: F has one flat, B♭ two, E♭ three, A♭ four, D♭ five, G♭ six and C♭ seven.

Written as a circle, the keys run clockwise C, G, D, A, E, B, F♯ and counterclockwise C, F, B♭, E♭, A♭, D♭, G♭. The two sides meet at the bottom, where three pairs of keys sound the same on the piano: B and C♭, F♯ and G♭, C♯ and D♭. That is why there are 15 key signatures but only 12 different major scales.

The sharps are added in a fixed order: F♯ C♯ G♯ D♯ A♯ E♯ B♯. A common memory aid is “Father Charles Goes Down And Ends Battle”. The flats are added in the reverse order: B♭ E♭ A♭ D♭ G♭ C♭ F♭, or “Battle Ends And Down Goes Charles' Father”. D major, with two sharps, takes the first two from the list: F♯ and C♯. A♭ major, with four flats, takes the first four: B♭, E♭, A♭ and D♭.

Find the key from the key signature

Two shortcuts turn a key signature into a key name in a second:

• Sharp keys: look at the last sharp in the signature and go up one half step. Last sharp G♯? The key is A major. Last sharp E♯? The key is F♯ major.
• Flat keys: the second-to-last flat is the name of the key. Flats B♭ E♭ A♭? The second-to-last is E♭, so the key is E♭ major. The only key you must memorize is F major, which has a single flat, B♭.

Each major key also shares its key signature with a minor key, its relative minor, which starts on the 6th note of the major scale. C major and A minor both have no sharps or flats; G major and E minor both have one sharp. When a piece has one sharp and keeps landing on E, it is probably in E minor.

All 12 major scales

The table lists the keys in circle-of-fifths order: the sharp keys first, from C to F♯, then the flat keys from F to D♭. D♭ major (five flats) uses the same piano keys as C♯ major (seven sharps). Most music is written in D♭, because five flats are easier to read than seven sharps: D♭ E♭ F G♭ A♭ B♭ C.

Read each row from left to right and check it against the formula. You will see every letter exactly once and either sharps or flats, never both. You will also see the circle at work: every key a 5th up from the last keeps six notes and raises one by a half step. G major is C major with F raised to F♯; D major is G major with C raised to C♯.

The chords inside a major scale

Stack every other note of the scale on each degree and you get the seven chords of the key. In C major they are:

Every major key follows the same pattern: major, minor, minor, major, major, minor, diminished. So in D major the chords are D, Em, F♯m, G, A, Bm and C♯dim. Practicing a scale and then its seven chords is the fastest way to understand why songs in a key use the chords they do. The I, IV and V chords (C, F and G in C major) carry most folk, country and early rock songs.

How to practice major scales on piano

The difficulty on piano is the fingering, not the notes. Right hand, one octave, for C, G, D, A and E major: 1 2 3 1 2 3 4 5, where 1 is the thumb. The thumb passes under after the 3rd finger. The left hand plays the same scales going up as 5 4 3 2 1 3 2 1: the 3rd finger crosses over the thumb.

Some keys change this pattern. F major in the right hand is 1 2 3 4 1 2 3 4, because the thumb should not land on B♭. In scales with many black keys, such as D♭, G♭ and B, the thumbs go on white keys and the long fingers take the black keys. D♭ major in the right hand, for example, is 2 3 1 2 3 4 1 2, with the thumb on F and C.

1. Hands separately first. One octave, quarter notes, metronome at 60 BPM. Every note even in volume and length.
2. Check the thumb crossing. The hand should glide, not jump. If the arm twists or the wrist lifts, slow down.
3. Two octaves, then hands together. Start with C, G and D major, where both hands are easy, before moving to keys with more black keys.
4. Eighth notes at 60 BPM, then raise the tempo by 4–8 BPM when the scale is clean three times in a row.
5. Follow the circle of fifths. Learn one new key per week, each with one more sharp or flat than the last.

How to practice major scales on guitar

On guitar the fingering is a matter of shapes. A good first pattern is a one-octave scale with the root on the 6th string. For G major, put your second finger on the 6th string at the 3rd fret:

• 6th string: fret 3 (G, finger 2), fret 5 (A, finger 4).
• 5th string: fret 2 (B, finger 1), fret 3 (C, finger 2), fret 5 (D, finger 4).
• 4th string: fret 2 (E, finger 1), fret 4 (F♯, finger 3), fret 5 (G, finger 4).

That shape is movable. There are no open strings in it, so sliding it up two frets gives A major (root on the 5th fret), and sliding it to the 8th fret gives C major. One shape, 12 keys. Learn the note names on the 6th string (E at the open string, G at fret 3, A at fret 5, C at fret 8) and you can start any major scale there.

Then play the same scale along a single string, using the 2 2 1 2 2 2 1 fret pattern, to see how the notes lie along the neck. Saying the note names out loud while you play helps you connect the shapes to the theory.

For timing, use the same method as piano: one note per click at a slow tempo, then eighth notes, alternate picking down-up, and raise the tempo in small steps. A clean, even scale at 80 BPM is worth more than a fast one with uneven notes.
