Chord Extensions (Simple Explanation):

Chord extensions are extra notes added to basic triads (3-note chords) to make them sound richer or more colorful.

---

Basic Triad (3 notes):

Root + 3rd + 5th
Example: C major = C + E + G

---

Adding Extensions:

1. 7th – adds the 7th note from the scale

Cmaj7 = C + E + G + B

C7 (dominant) = C + E + G + Bb

2. 9th – adds the 9th (same as 2nd note, but higher)

C9 = C + E + G + Bb + D

3. 11th – adds the 11th (same as 4th)

C11 = C + E + G + Bb + D + F

4. 13th – adds the 13th (same as 6th)

C13 = C + E + G + Bb + D + F + A

---

Important Notes:

Extensions are usually built on dominant, major, or minor 7th chords.

Some notes may be left out to avoid a muddy sound (especially on piano).

Not all extensions are used at once; sometimes just the 7th or 9th is added.

---

Summary:

Chord extensions add flavor. The more you add (7th, 9th, 11th, 13th), the richer the harmony becomes.

1. What is a Key Signature?

A key signature is a set of sharp (♯) or flat (♭) symbols placed at the beginning of the staff, right after the clef. It tells us which notes are consistently sharped or flatted throughout a piece, thus indicating the tonal center (key) of the music.

For example:

If you see one sharp (F♯), you’re in the key of G major or E minor.

If you see three flats (B♭, E♭, A♭), you're in E♭ major or C minor.

2. Major and Relative Minor Keys

Each major key has a relative minor that shares the same key signature.

Major Key Relative Minor Key Signature

C Major A Minor No sharps/flats
G Major E Minor 1 sharp (F♯)
D Major B Minor 2 sharps (F♯, C♯)
A Major F♯ Minor 3 sharps
E Major C♯ Minor 4 sharps
B Major G♯ Minor 5 sharps
F♯ Major D♯ Minor 6 sharps
C♯ Major A♯ Minor 7 sharps
F Major D Minor 1 flat (B♭)
B♭ Major G Minor 2 flats
E♭ Major C Minor 3 flats
A♭ Major F Minor 4 flats
D♭ Major B♭ Minor 5 flats
G♭ Major E♭ Minor 6 flats
C♭ Major A♭ Minor 7 flats

3. The Circle of Fifths (Memory Tool)

The Circle of Fifths helps you memorize key signatures in order of increasing sharps or flats.

Sharps (Clockwise): C → G → D → A → E → B → F♯ → C♯
(Add a sharp each time)

Flats (Counterclockwise): C → F → B♭ → E♭ → A♭ → D♭ → G♭ → C♭
(Add a flat each time)

TIP: The order of sharps is F♯, C♯, G♯, D♯, A♯, E♯, B♯
The order of flats is B♭, E♭, A♭, D♭, G♭, C♭, F♭

4. How to Read and Apply Key Signatures

When reading a piece:

Look at the key signature on the staff.

Determine if it's a major or minor key (context or tonic note usually tells you).

Apply the sharps or flats to every note on the corresponding pitch unless overridden by accidentals.

Example:

If the key signature has 2 sharps, every F and C is sharped unless notated otherwise.

---

Practice Exercise:

1. What key has 3 flats?
→ E♭ Major / C Minor

2. What is the relative minor of G Major?
→ E Minor

3. Name the sharps in the key of B Major.
→ F♯, C♯, G♯, D♯, A♯
