Section 3.5 of the ABRSM Grade 5 Music Theory exam tests your ability to identify the correct clef for a minor scale.
You’ll be given a question like this: “Circle one clef for each scale to form minor scales.”
You’ll see a scale written without a clef. Your job is to try each clef one by one until you find the correct one.
To answer these questions, you need:
- A good understanding of key signatures
- Knowledge of minor scales (harmonic and melodic)
- The ability to read all four clefs
Here’s everything you need to know.
The Method
- Try each clef one by one
- Identify the key based on the first note
- Check the key signature using your table
- Look for raised notes (6th/7th in melodic, 7th in harmonic)
- Eliminate wrong options and select the correct clef
Worked Example 1: B♭ Harmonic Minor (Bass Clef)
The question: A scale is written without a clef. Determine which clef makes it a correct minor scale.
Step 1: Try the treble clef
If we put a treble clef, the first note is G♭.
Is there a G♭ minor key in the key signature table?
No – G♭ minor doesn’t exist as a standard key.
Result: ❌ Treble clef ruled out.
Step 2: Try the bass clef
If we put a bass clef, the first note is B♭.
This makes it potentially a B♭ minor scale.
Check the key signature table:
- B♭ minor = column 5 (B♭, E♭, A♭, D♭, G♭)
Now check the scale:
| Accidental | Present? | Notes |
|---|---|---|
| B♭ | ✅ Yes | |
| E♭ | ✅ Yes | |
| A♭ | ❌ No | But this is the 7th note – in harmonic minor it can be raised! |
| D♭ | ✅ Yes | |
| G♭ | ✅ Yes |
The A♭ is raised to A♮ – this is correct for harmonic minor (7th note raised).
Result: ✅ Bass clef is correct.
Answer: Bass clef (B♭ harmonic minor)
Worked Example 2: A Melodic Minor (Alto Clef)
The question: A scale is written without a clef. Determine which clef makes it a correct minor scale.
Step 1: Try the treble clef
First note = G → G minor?
Check key signature table:
- G minor = column 2 (B♭, E♭)
Does the scale have B♭ and E♭? No – it has sharps.
Result: ❌ Treble clef ruled out.
Step 2: Try the bass clef
First note = B → B minor?
Check key signature table:
- B minor = column 2 (F♯, C♯)
Does the scale have F♯ and C♯? No – it has G♯ and A♯.
Result: ❌ Bass clef ruled out.
Step 3: Try the alto clef
First note = A → A minor?
Check key signature table:
- A minor = column 0 (no sharps or flats)
The scale has F♯ and G♯.
In an ascending melodic minor scale, the 6th and 7th notes are raised.
A minor melodic ascending:
- A – B – C – D – E – F♯ – G♯ – A
This matches exactly!
Result: ✅ Alto clef is correct.
Answer: Alto clef (A melodic minor ascending)
Worked Example 3: G Harmonic Minor (Tenor Clef)
The question: A scale is written without a clef. Determine which clef makes it a correct minor scale.
Step 1: Try the treble clef
First note = A → A minor?
A minor has no sharps or flats. But the scale has flats.
Result: ❌ Treble clef ruled out.
Step 2: Try the bass clef
First note = C → C minor?
Check key signature table:
- C minor = column 3 (B♭, E♭, A♭)
The scale has B♭ and E♭, but also has a B♯ (which doesn’t fit – B♯ is enharmonic to C).
Result: ❌ Bass clef ruled out.
Step 3: Try the alto clef
First note = B → B minor?
Check key signature table:
- B minor = column 2 (F♯, C♯)
The scale has flats, so this doesn’t match.
Result: ❌ Alto clef ruled out.
Step 4: Try the tenor clef
First note = G → G minor?
Check key signature table:
- G minor = column 2 (B♭, E♭)
Check the scale:
| Accidental | Present? | Notes |
|---|---|---|
| B♭ | ✅ Yes | |
| E♭ | ✅ Yes | |
| F♯ | ✅ Yes | Raised 7th in harmonic minor |
G minor harmonic:
- G – A – B♭ – C – D – E♭ – F♯ – G
This matches exactly!
Result: ✅ Tenor clef is correct.
Answer: Tenor clef (G harmonic minor)
Summary Table
| Example | Clef | Key | Scale Type | Reason |
|---|---|---|---|---|
| 1 | Bass | B♭ minor | Harmonic | 7th note raised (A♭ → A♮) |
| 2 | Alto | A minor | Melodic ascending | 6th and 7th raised (F♯, G♯) |
| 3 | Tenor | G minor | Harmonic | 7th note raised (F♯) |
The Process (Step-by-Step)
- Try each clef one by one (treble → bass → alto → tenor)
- Identify the key from the first note
- Check the key signature table for the correct accidentals
- Look for raised notes – these indicate harmonic or melodic minor
- Eliminate clefs that don’t match the key signature or scale type
- Select the correct clef
Common Pitfalls to Avoid
- Forgetting about minor scales. The key might be minor, not major!
- Ignoring raised 6th/7th notes. These are clues for melodic/harmonic minor.
- Not using the key signature table. It’s your best friend in these questions.
- Misreading clefs. Make sure you know where middle C is in each clef.
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 minor scale identification 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.
