The Major Scale, Step by Step

By Tissimo Team

Published October 18, 2026

Play every white key from middle C up to the next C, one at a time, and you have played a major scale. If you know "Joy to the World," you have sung one too: the carol opens by walking straight down a major scale, all eight notes, before it turns around. Every major scale is built the same way, from one fixed pattern of whole steps and half steps.

This guide builds that pattern the way a teacher would at the piano: the two sizes of step, the recipe that puts them in order and the same recipe moved to G, F and any other key. Then come the numbers and names of the scale's seven notes, and the three of them, 1, 4 and 5, that carry the most weight in harmony. Each section links the free worksheets that go with it, and a ten-minute daily routine closes the lesson.

Half steps and whole steps

The black keys come in groups of two and three up the whole piano (only the lowest one stands alone), and The piano keyboard shows how to find every letter from them. Now count every key, black and white. A half step is the move from one key to its nearest neighbor, with nothing in between: C to C♯, or C♯ to D. A sharp raises a note one half step and a flat lowers it one half step. A half step is the smallest step the piano can take. Most half steps join a white key to a black one, but two pairs of white keys have no black key between them, E–F and B–C, so those are half steps too.

A whole step is two half steps: skip exactly one key. Going up from C, D, F, G or A, the key you skip is black, so C–D, D–E, F–G, G–A and A–B are whole steps. From E or B the next key up is already white, so the whole step skips a white key and lands on a black one: E to F♯, B to C♯. Our Half steps & whole steps sheet warns about the look-alike: C–D and E–F both look like next-door white keys, but a black key hides between C and D, so C–D is a whole step and E–F only a half. Count keys, not white keys.

Four drawn keyboards from C to C. Top row, half steps: C to C-sharp, with C-sharp numbered 1; E to F and B to C, with F and the top C numbered 1. Bottom row, whole steps: C to D, with the skipped black key C-sharp outlined and numbered 1 and D numbered 2; E to F-sharp, with the skipped white key F outlined and numbered 1 and F-sharp numbered 2

Five steps counted key by key. A half step goes to the very next key (C to C♯; E to F and B to C). A whole step skips one key, a black one (C to D, past C♯) or a white one (E to F♯, past F).

On the staff, a step to the next letter moves from a line to the next space, or from a space to the next line. Between neighboring letters, a whole step is called a major 2nd and a half step a minor 2nd; the "2nd" comes from counting letters, C as 1 and D as 2 (Major & minor 2nds and 3rds). A half step can also keep its letter and add a sharp or a flat, as F to F♯ does: the same size, but not a 2nd. In a major scale every step moves to the next letter, so all of its steps are 2nds: major ones for W, minor ones for H.

Four short treble staves, each with two whole notes and a label: C to D, a whole step to the next letter, a major 2nd; E to F-sharp, a whole step to the next letter, a major 2nd; E to F, a half step to the next letter, a minor 2nd; F to F-sharp, a half step on the same letter, not a 2nd

Four steps from our Half steps & whole steps sheet. C–D and E–F♯ are whole steps (major 2nds), E–F is a half step to the next letter (a minor 2nd), and F–F♯ is a half step on the same letter, which is not a 2nd.

Whole step or half step? gives you 30 to work out, first on the keyboard, then on the staff, then by writing the note yourself.

The recipe: W-W-H-W-W-W-H

Play C, D, E, F, G, A, B and C, and measure each move. Seven moves join the eight notes, and they come in this order: whole, whole, half, whole, whole, whole, half, or W-W-H-W-W-W-H for short. That order is what makes a scale major. On the white keys from C, the two half steps land exactly on E–F and B–C, between notes 3 and 4 and between notes 7 and 8. That is why C major needs no sharp or flat; start anywhere else and the recipe needs at least one, as the next section shows.

The C major scale in whole notes on a treble staff, with the letters C D E F G A B C under the notes, a W or H badge between each pair of letters, reading W W H W W W H, and the numbers 1 to 8 below; underneath, a drawn keyboard from C to C with the same eight white keys shaded and numbered and the same seven badges under the gaps between them

C major on the staff and on the keys. The badges between the notes are the seven steps. The two half steps (H) fall between notes 3 and 4 (E–F) and between 7 and 8 (B–C), the two places where no black key sits between neighboring white keys.

Three details matter. Each of the seven letters appears once, in order, before the top C starts them again: nothing skipped, nothing doubled. The two halves of the scale match, since C–D–E–F and G–A–B–C both go whole, whole, half, with the whole step F–G joining them. And the first five notes, C to G, are the C five-finger position: whole, whole, half, whole, the pattern our 5-Finger Positions in Every Key chart prints over its twelve major positions. Listen closely to the last step: B rising to C is "the 7 leaning home to 8," in the words of The major scale sheet.

Moving the recipe: G major and F major

Now start on G and play only white keys: G, A, B, C, D, E, F, G. The first five steps follow the recipe, but the last two come out backward. E to F is a half step where the recipe wants a whole step, and F to G is a whole step where it wants a half. One change fixes both: raise F to F♯. Now E–F♯ is a whole step, F♯–G a half step, and the recipe is back. The G 5-Finger Scale covers its first five notes.

Two treble staves of whole notes from G to G with letters and step badges under them. White keys only: G A B C D E F G, steps W W H W W H W, with the sixth and seventh badges circled and labeled should be W and should be H. G major: the same notes with F-sharp, steps W W H W W W H

Starting on G. On the white keys alone, steps 6 and 7 come out half, whole (circled). Raising F to F♯ makes them whole, half, as the recipe needs (the changed letter is underlined).

Start on F and the trouble comes earlier. A to B is a whole step where step 3 should be a half, and B to C a half step where step 4 should be a whole. Lower B to B♭ and both come right. Our F 5-Finger Scale sheet has you play F–G–A–B–C with a plain B on purpose, then with B♭. One-Octave Scales: G, F & D gives the three scales with fingering, and Scales in Every Key has G and F major over two octaves, with audio.

Two treble staves of whole notes from F to F with letters and step badges under them. White keys only: F G A B C D E F, steps W W W H W W H, with the third and fourth badges circled and labeled should be H and should be W. F major: the same notes with B-flat, steps W W H W W W H

Starting on F. On the white keys alone, steps 3 and 4 come out whole, half (circled). Lowering B to B♭ makes them half, whole (the changed letter is underlined).

That is what sharps and flats do in a major scale: they keep the recipe intact on a new starting note. F♯ is G major's 7th note and B♭ is F major's 4th, and the pattern continues. Going on from C through G, D, A, E, B, F♯ and C♯, each key adds one sharp, and the new sharp is its 7th note (D major adds C♯). Through F, B♭, E♭, A♭, D♭, G♭ and C♭, each key adds one flat, and the new flat is its 4th note (B♭ major adds E♭).

Work out any major scale in three steps

You can build any major scale on paper before you play it:

Write the letters from the starting note up to the same letter, every letter once, in order: D E F G A B C D.
Check each step against W-W-H-W-W-W-H, counting keys.
Working up from the starting note, fix each wrong step by adding a sharp or a flat to its upper note, never by changing a letter.

Infographic titled Build any major scale with three numbered cards joined by arrows: 1, Write the letters, Tonic to tonic, each letter once, with a pencil icon; 2, Check every step, W W H W W W H, with a magnifying glass icon; 3, Fix the wrong steps, Add a sharp or a flat, with a wrench icon

The three steps on one card.

From D, E–F is a half step where the recipe wants a whole, so F becomes F♯; later B–C is too small as well, so C becomes C♯. From B♭, D–E is a whole step where the recipe wants a half, so E becomes E♭. For all 15 major keys on our Key Signatures: Major & Minor chart, the method gives the standard scale, and none of them mixes sharps with flats. Write the scales has D, B♭ and E major to try, plus three minor scales, with the answers printed upside down.

Two staves of whole notes with letters and step badges under them: D major in the treble clef, D E F-sharp G A B C-sharp D, with slurs joining F-sharp to G and C-sharp to D; B-flat major in the bass clef, B-flat C D E-flat F G A B-flat, with slurs joining D to E-flat and A to B-flat; both read W W H W W W H

D major and B♭ major as on the answer key of our Write the scales sheet, where a slur joins each half step: F♯–G and C♯–D in D major, D–E♭ and A–B♭ in B♭ major.

From scale to key signature

Writing F♯ in front of every F soon gets tiring, so music in G major prints the sharp once, at the start of every line: the key signature. A signature simply lists its scale's sharps or flats, always in the same order: sharps F C G D A E B, flats the reverse, B E A D G C F. Name the Key Signatures gives you eight to read, each with its relative minor (the minor key that shares the signature), and Write the key signatures twelve to write.

Scale degrees: a number and a name for every note

Each note of a scale has a number, counted up from the starting note: its scale degree. The starting note is the tonic, degree 1, and the scale takes its name from it. Degrees run from 1 to 7, and the top note is the tonic again, numbered 1 or, when you count up through the octave, 8. The numbers move with the key: degree 5 is G in C major and D in G major.

Each degree has a name as well (Scale Degree Names): 1 tonic, 2 supertonic, 3 mediant, 4 subdominant, 5 dominant, 6 submediant and 7 leading tone. The names describe positions. The supertonic sits just above the tonic. The dominant sits a 5th above the tonic, and the subdominant the same distance below it, which is why F, a 5th below C (count down C, B, A, G, F, with C as 1), is C major's subdominant even though it is the 4th note up. The mediant lies halfway from the tonic up to the dominant, and the submediant halfway down to the subdominant. The leading tone sits a half step below the tonic and leads up into it.

The C major scale in whole notes on a treble staff with four rows of labels under the notes: the letters C D E F G A B C; the degree numbers 1 to 7 and 1 again; the names Tonic, Supertonic, Mediant, Subdominant, Dominant, Submediant, Leading tone, Tonic; and the syllables do re mi fa sol la ti do

The degrees of C major: under each note, its letter, degree number, degree name and movable-do syllable. The top C is the tonic again.

If you have sung do-re-mi, you have already sung the degrees in order. In movable do, do is always the tonic of a major key, re is degree 2, and so on up to ti, degree 7. The hand signs that go with the syllables are named after the 19th-century English music teacher John Curwen, and the Kodály method still uses them.

A printed page from 1884 headed Mental effects and manual signs of tones in key, showing seven drawn hands, each labeled with a sol-fa syllable and a short description, beside a table that pairs each syllable with its degree number and the name on the page, from doh, 1, the Major Tonic, to te, 7, the Major Leading Tone

Page viii of John Curwen's Standard Course (seventh edition, London, 1884): a hand sign for each tonic sol-fa syllable, with the degree name Curwen gives it (transcribed at right, with degree numbers added). The same page calls doh, me and soh "the Tonic Chord," fah, lah and doh "the Subdominant Chord," and soh, te and ray "the Dominant Chord." Image: public domain, via the Internet Archive.

Name the scale degrees gives you 20 questions in eight major keys and four minor ones.

Tonic, subdominant and dominant

Build a triad (three notes a 3rd apart, on every other letter) on degrees 1, 4 and 5 and you get the primary chords, written in roman numerals as I, IV and V. In C major they are C–E–G, F–A–C and G–B–D, all three major chords. Between them they hold every note of the scale, which is one reason three chords can accompany so many simple melodies. Tonic & dominant starts with I and V, The primary chords: I, IV & V adds IV, and The Primary Chords in Every Key gives all three in every key, with audio.

Three treble staves with one chord each, labeled I tonic C E G, IV subdominant F A C, and V dominant G B D; below them seven boxes for the notes C to B, each showing the chords that contain it: C in I and IV, D in V, E in I, F in IV, G in I and V, A in IV, B in V

The primary chords of C major, from our Primary Chords in Every Key sheet. Every note of the scale belongs to at least one of them: C to I and IV, G to I and V, and each of the others to just one.

Each chord has its own job. I is home: stable and at rest, and in music from Bach to Brahms most pieces begin and end on it. V is away, and it pulls back toward home. It holds degree 7, the leading tone, a half step below the tonic, and V is the only primary chord that contains it. With a 7th added (G7: G–B–D–F), V also holds F, which leans down to E. IV is the gentle away: less settled than I, less restless than V, and often the chord that leads on to V. To feel V7 pull home under your hand, try the left-hand slide from C–E–G to B–F–G and back on Tonic & dominant harmonies.

Two-chord endings such as V7–I are called cadences. V–I is the authentic cadence, music's full stop. IV–I is the plagal cadence, nicknamed the "Amen" cadence because hymns so often set that word to it. A phrase that stops on V ends in a half cadence, which sounds unfinished. Cadences has all three, with audio.

Three treble staves, each with two chords and chord symbols above: G7 then C, labeled V7 to I, authentic cadence, B rises to C, F falls to E; F then C, labeled IV to I, plagal Amen cadence, F falls to E, A to G; C then G, labeled I to V, half cadence, the phrase stops on V

The three cadences of our Cadences sheet, in the shapes it uses. Authentic: G7 as B–F–G, then C–E–G, with B rising to C and F falling to E. Plagal: F as C–F–A, then C–E–G. Half: C–E–G, then G as B–D–G.

Beyond classical music, the chords of a typical "three-chord song" are I, IV and V, and the basic 12-bar blues runs mainly on the same three.

A ten-minute daily routine

Give each step two minutes a day, and add one new key a week, in the order of Your Daily Technique Routine: C, then one step clockwise round the circle of fifths (G, D, A and on).

Steps. From any key, play a half step up and back, then a whole step, naming each one. Then work through one part of Whole step or half step?.
Recipe. Play C major slowly, as on The major scale, and say the steps as you go: whole, whole, half… Then play this week's scale the same way.
New key. Write this week's scale with the three steps above, play it, and check it on Scales in Every Key.
Degrees. Play 1 to 7 and stop, the test on Scale Degree Names. Let the leading tone hang, then play the tonic. Sing the degrees as numbers or as do-re-mi.
Chords. Play I–IV–V–I in this week's key, then V–I and IV–I (The Primary Chords in Every Key).

Infographic titled Ten minutes a day with five numbered cards: 1, Steps, Half or whole?; 2, Recipe, Say every step; 3, New key, Write it, then play it; 4, Degrees, Stop on 7, then home; 5, Chords, I, IV, V, I; with the line About two minutes each

The routine on one card, about two minutes a step.
