Beginner Music Theory

Sixteen lessons, from the musical alphabet to enharmonic spelling.

Follows the Beginner Theory packet, page for page.

Part One

Pitch and the Staff

Packet pages 1–2

Lesson 1 · Page 1

The Musical Alphabet

A
B
C
D
E
F
G
A

Above G, start again at A. Below A, continue down to G. The pattern never changes.

Eight letters from A up to the next A is an octave — the same letter, higher.

Practice · Page 1

Now try it

Fill in the missing letters, then answer the five questions using the alphabet grid.

AB__DE__GA

Worked example: D is 3 letters higher than A. Count up — A, B, C, D.

Lesson 2 · Page 2

The Musical Staff

Five lines and four spaces. Each one stands for a piano key and gives a note its letter name.

5 1
line note space note

Lines are numbered from the bottom up: line 1 is the lowest.

Practice · Page 2

Now try it

The Musical Staff is made up of __ lines and __ spaces.
The Musical Staff gives _______ their letter names.
The Musical Staff represents the keys of the _______.

Then connect the dots to build your own staff — five lines, evenly spaced.

Part Two

Reading Notes

Packet pages 3–7

Lesson 3 · Page 3

Clefs, Notes, and Their Names

A clef sets the starting letter of the staff. Your instrument decides which one you read.

𝄞
Treble clef
Flute, Oboe, Clarinet, Saxophone, Trumpet, Horn, Percussion
𝄢
Bass clef
Bassoon, Trombone, Euphonium, Tuba
Lesson 3 · Page 3

Lines and Spaces by Name

Treble spaces
F A C E
Remember: FACE
Treble lines
E G B D F
Every Good Boy Does Fine
Bass spaces
A C E G
All Cows Eat Grass
Bass lines
G B D F A
Good Boys Do Fine Always

Both mnemonics read bottom to top.

Practice · Page 4

Naming Notes on the Staff

Draw your clef sign, then write the letter name under each note. Space notes first, then line notes.

𝄞
F A C E

Worked example in treble clef — the four spaces spell FACE.

Lesson 5 · Page 5

Expanding the Staff

When notes run past the top or bottom, ledger lines add more lines and spaces. The letters keep marching in order.

𝄞

C
A
C
Practice · Page 5

Now try it

Draw your clef sign and name each note, including the ones on ledger lines.

Strategy: find the nearest line note you know by heart, then step letter by letter to the note in question.

Practice · Page 6

Notes In and Out of the Staff

Seven rows, mixing notes on the staff with notes on ledger lines. Draw your clef, then name every note.

Say the letter out loud before you write it.
Work left to right. Do not skip the hard ones.
Lesson 7 · Page 7

Drawing Notes and Stems

Third line and above
Stem down, on the left side.
Third line and below
Stem up, on the right side.
Practice · Page 7

Now try it

Draw your clef, then draw the correct note above each letter name. Note heads first, stems second.

Check yourself: is the note head centered on its line, or filling its space?

Part Three

Accidentals and Key Signatures

Packet pages 8–11

Lesson 8 · Page 8

Accidentals

A
B
C
D
E
F
G
A
B
B♭A♯
D♭C♯
E♭D♯
G♭F♯
A♭G♯
B♭A♯
Sharp raises a note to the very next key.
Flat lowers a note to the very next key.
Natural cancels an accidental.
Lesson 8 · Page 8

Where the Sign Goes

On the staff
♯ before the note
The sign is drawn to the left of the note head.
In writing
F♯ after the letter
Read aloud as letter name, then accidental.

Say "F sharp" — never "sharp F".

Practice · Page 8

Now try it

Name each note with its accidental, then draw notes with accidentals above the given names.

G♯D♮E♭B♭A♯C♮F♯D♭C♯B♮D♯A♭

Draw the sign to the left of the note head, on the same line or space.

Practice · Page 9

Notes and Accidentals

Seven rows of mixed notes — on the staff, on ledger lines, with and without accidentals.

Name the letter first. Add the accidental second.
A natural sign means the plain letter — no sharp, no flat.
Lesson 10 · Page 10

How Long an Accidental Lasts

Once written, an accidental holds for every note on that same line or space — until the barline, or until a natural cancels it.

After the barline, it has to be written again.

𝄞
B♭ B♭ B♭
B — the flat is gone after the barline
Lesson 10 · Page 10

Collecting Accidentals

When music uses the same accidentals over and over, they move to the front of the line. That collection is a key signature.

One flat on the B line — every B is played B flat.
♭♭
Two flats — every B and every E is flat.

High or low, every note of that letter is affected.

Practice · Page 10

Now try it

Write the letter and accidental under every note. Watch what carries through the measure and what resets at the barline.

The second note of a measure often carries an accidental you cannot see — it was written on the first.

Practice · Page 11

Reading Key Signatures

For each key signature, name every letter the accidentals affect. One flat, then two, all the way to seven — then the same for sharps.

♭    All of my ___ are flat
♭♭    All of my ___ and ___ are flat
♯    All of my ___ are sharp
Part Four

Major Scales

Packet pages 12–15

Lesson 12 · Page 12

Half Steps and Whole Steps

A
B
C
D
E
F
G
A
Half step
Two keys right next to each other. B to C, E to F, A to A♯.
Whole step
Two half steps, with one key in between. A to B, D to E, F to G.
Lesson 12 · Page 12

Building a Major Scale

Eight notes in alphabetical order, spaced by one fixed pattern of steps.

C
whole
D
whole
E
half
F
whole
G
whole
A
whole
B
half
C

Whole, whole, half — whole, whole, whole, half.

Practice · Page 12

Now try it

Complete each major scale. The key signature has already spaced the steps for you.

G   ___ ___ ___ ___ ___ ___   G
C   ___ ___ ___ ___ ___ ___   C
F   ___ ___ ___ ___ ___ ___   F
B♭   ___ ___ ___ ___ ___ ___   B♭
Lesson 13 · Page 13

The Order of Sharps and Flats

Sharps
F C G D A E B
Fat Cats Go Down Alleys Eating Birds
Flats
B E A D G C F
BEAD Greatest Common Factor

The flats are the sharps in reverse.

Practice · Page 13

Now try it

Draw your clef, then draw the key signature for each scale. Sharps and flats must go in the correct order.

ADGFB♭E♭

A sharp in the wrong position is a wrong key signature.

Lesson 14 · Page 14

Naming a Scale From Its Key Signature

The C rule
C♭, C, and C♯ are all-or-nothing — seven flats, none, or seven sharps.
The last sharp
In sharp keys, go one half step up from the last sharp. F♯ up to G.
Second to last flat
In flat keys, the second-to-last flat names the scale. F major is the exception.

Memorizing the key signatures is still the fastest route. These are the backup.

Practice · Page 14

Now try it

Write the name of the scale for each key signature.

no sharps or flats    ___ Major
♯♯♯♯    ___ Major
♭♭♭    ___ Major

A♭ Major has ___ flats in its key signature.
Part Five

Enharmonic Notes

Packet page 16

Lesson 16 · Page 16

One Sound, Two Names

When a pitch can be called by more than one letter name, those names are enharmonic.

A♯ = B♭D♯ = E♭F♯ = G♭C♯ = D♭

B and C have no key between them, and neither do E and F. So B♯ sounds like C, and C♭ sounds like B.

E♯ sounds like F, and F♭ sounds like E. Which spelling you use is decided by the key.

Practice · Page 16

Now try it

Name each note and its enharmonic spelling, then complete the pairs.

C♯ and ___     D♯ and ___     E♯ and ___
C♭ and ___     D♭ and ___     E♭ and ___
