Section 3.4 of the ABRSM Grade 5 Music Theory exam tests your ability to complete a melodic minor scale.
You’ll be given a question like this: “Tick one box for X and one box for Y to show which notes are needed to complete the scale of A sharp melodic minor.”
To answer these questions, you need to know how melodic minor scales work – and when to raise the 6th and 7th notes.
Here’s everything you need to know.
Quick Revision: Major and Minor Scales
Major Scales
Simply follow the given key signature – no additional accidentals.
Example: C major
- Key signature: none
- Scale: C – D – E – F – G – A – B – C
Harmonic Minor Scales
Follow the key signature, but raise the 7th note by one semitone (both ascending and descending).
Example: C minor harmonic
- Key signature: B♭, E♭, A♭
- Scale: C – D – E♭ – F – G – A♭ – B♮ – C
Melodic Minor Scales
| Direction | Rule |
|---|---|
| Ascending | Raise the 6th and 7th notes by one semitone |
| Descending | Do not raise anything – follow the key signature |
Example: C minor melodic (ascending)
- C – D – E♭ – F – G – A♮ – B♮ – C
Example: C minor melodic (descending)
- C – B♭ – A♭ – G – F – E♭ – D – C
Using the Key Signature Table
To answer Section 3.4 questions, you need to:
- Find the key in your key signature table
- Identify the accidentals in that key
- Apply the melodic minor rules (raise 6th and 7th for ascending, nothing for descending)
Worked Example 1: A♯ Melodic Minor (Ascending)
The question: Complete the scale of A♯ melodic minor going up.
Step 1: Find A♯ minor in the key signature table
A♯ minor is in column 7 (all sharps).
The key signature has:
- F♯, C♯, G♯, D♯, A♯, E♯, B♯
Step 2: Identify the 6th and 7th notes
In A♯ minor:
- 6th note = F♯
- 7th note = G♯
Step 3: Apply the melodic minor rule (ascending)
For an ascending melodic minor scale, raise the 6th and 7th notes by one semitone:
- F♯ → F𝄪 (F double sharp)
- G♯ → G𝄪 (G double sharp)
Answer
The missing notes are F double sharp and G double sharp.
Worked Example 2: A♯ Melodic Minor (Descending)
The question: Complete the scale of A♯ melodic minor going down.
Step 1: Find A♯ minor in the key signature table
Same as above – column 7 with all sharps.
Step 2: Apply the melodic minor rule (descending)
For a descending melodic minor scale, do not raise anything.
The 6th and 7th notes follow the original key signature:
- 6th note = F♯
- 7th note = G♯
Answer
The missing notes are F sharp and G sharp.
Summary Table: A♯ Melodic Minor
| Scale Direction | 6th Note | 7th Note |
|---|---|---|
| Ascending | F𝄪 (F double sharp) | G𝄪 (G double sharp) |
| Descending | F♯ | G♯ |
Quick Reference: Minor Scale Rules
| Scale Type | Rule |
|---|---|
| Natural Minor | Follow the key signature only |
| Harmonic Minor | Raise the 7th note (both directions) |
| Melodic Minor (ascending) | Raise the 6th and 7th notes |
| Melodic Minor (descending) | Follow the key signature (no raises) |
Common Pitfalls to Avoid
- Raising notes in a descending melodic minor scale. Descending melodic minor follows the key signature – no raises!
- Forgetting to raise both the 6th and 7th in ascending melodic minor. Both need to be raised, not just the 7th.
- Using the wrong key signature. Always check your key signature table carefully.
How to Use the Key Signature Table for This Section
| Step | Action |
|---|---|
| 1 | Find the key in your table (e.g., A♯ minor = column 7) |
| 2 | Note the accidentals in that key |
| 3 | Identify the 6th and 7th notes by letter name |
| 4 | Apply the harmonic/melodic minor rule |
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 melodic minor 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.
