Section 3.6 of the ABRSM Grade 5 Music Theory exam tests your knowledge of chromatic scales.
You’ll be given a question like this: “Circle true or false for each statement. This is the correctly written chromatic scale beginning on D.”
A chromatic scale is simply a scale that covers every semitone within an octave. But there are specific rules about how it should be written.
Here’s everything you need to know.
What Is a Chromatic Scale?
A chromatic scale is a scale that includes all 12 semitones within an octave.
On a keyboard, this means playing every single key – both white and black – between a note and its octave.
Example: Chromatic scale starting on D (ascending)
D – D♯ – E – F – F♯ – G – G♯ – A – A♯ – B – C – C♯ – D
This covers every semitone in the octave.
The Three Rules of Chromatic Scales
When checking if a chromatic scale is correctly written, you need to apply these three rules:
Rule 1: No Enharmonic Equivalents
A correctly written chromatic scale should not use enharmonic equivalents.
Wrong: E♯ followed by F (they’re the same pitch)
Right: E♯ followed by F♯ (different pitches)
Rule 2: Start and End on the Same Note
A chromatic scale must start and end on the same note name.
Wrong: Starts on E♯, ends on F (enharmonic equivalent)
Right: Starts on E♯, ends on E♯
Rule 3: No Three Letter Names in a Row
You should never have three consecutive notes with the same letter name.
Wrong: A – A♯ – A𝄪 (three A’s in a row)
Right: A – A♯ – B (different letter names)
Quick Reference: The Three Rules
| Rule | Explanation |
|---|---|
| 1 | No enharmonic equivalents |
| 2 | Start and end on the same note |
| 3 | No three letter names in a row |
Worked Example 1: Chromatic Scale on D (Correct)
The question: Is this a correctly written chromatic scale starting on D?
The scale: D – D♯ – E – F – F♯ – G – G♯ – A – A♯ – B – C – C♯ – D
Check the Rules
| Rule | Check | Verdict |
|---|---|---|
| 1. No enharmonic equivalents | All notes are distinct pitches | ✅ Pass |
| 2. Start and end on same note | Starts on D, ends on D | ✅ Pass |
| 3. No three letter names in a row | No three same letter names consecutively | ✅ Pass |
Answer: True ✅
Worked Example 2: Chromatic Scale on E♯ (Incorrect)
The scale: E♯ – F – F♯ – G♭ – G♯ – A – A♯ – A𝄪 – B♯ – C♯ – D – E – F
Check the Rules
| Rule | Check | Verdict |
|---|---|---|
| 1. No enharmonic equivalents | E♯ → F (same pitch!) | ❌ Fail |
| 1. No enharmonic equivalents | F♯ → G♭ (same pitch!) | ❌ Fail |
| 1. No enharmonic equivalents | A𝄪 → B♯ (same pitch!) | ❌ Fail |
| 1. No enharmonic equivalents | E♯ → F (start and end are enharmonic!) | ❌ Fail |
| 2. Start and end on same note | Starts on E♯, ends on F (different note name) | ❌ Fail |
| 3. No three letter names in a row | A – A♯ – A𝄪 (three A’s in a row!) | ❌ Fail |
| Missing semitones | Skips notes between G♯ and A, and D and E | ❌ Fail |
Answer: False ❌
Common Mistakes in Chromatic Scales
| Mistake | Example | Why It’s Wrong |
|---|---|---|
| Enharmonic equivalents | E♯ → F | Same pitch, wrong notation |
| Wrong start/end note | E♯ → F | Should start and end on E♯ |
| Three same letter names | A – A♯ – A𝄪 | Violates Rule 3 |
| Missing semitones | D → E (no black note) | Doesn’t cover all semitones |
How to Check a Chromatic Scale
- Start at the beginning and check every interval
- Count the semitones – there should be 12 in an octave
- Check for enharmonic equivalents (same pitch, different name)
- Check the start and end notes – they must be the same letter name
- Check for three letter names in a row
- Make sure no semitones are skipped
Quick Tip: The Keyboard Is Your Friend
The easiest way to check a chromatic scale is to use a keyboard:
- Place a finger on the starting note
- Move up one key at a time
- Check that every single key between the start and octave is included
- Check that the note names follow the rules
Practice Makes Perfect
Understanding the theory is one thing, but exam success comes from repeated, focused practice. That’s why my interactive practice site (app.owenmusictheory.com) can make all the difference in your preparation.
Here’s how the two practice modes work:
Drill Mode: Master One Section at a Time
Drill Mode is designed for targeted practice. You get access to all the questions organised section by section, just like the real exam. This means you can:
- Focus specifically on chromatic scales until it feels second nature
- Skip the sections you’re already confident in and spend your time where it matters most
- Practise the same question type repeatedly with virtually unlimited questions – you’ll never run out of fresh material
With instant feedback on every answer, you’ll learn from your mistakes immediately and reinforce correct answers right away.
Exam Mode: Simulate the Real Thing
When you’re ready to put it all together, Exam Mode gives you the full experience:
- Full-length papers in the exact format of the ABRSM exam
- Randomised questions each time you take a test – no two papers are the same
- A 2-hour time limit to help you build speed and stamina
- A final score and detailed feedback at the end, so you know exactly where you stand
This mode is invaluable for reducing exam-day anxiety. The more you practise under real conditions, the more confident you’ll feel when it counts.
