Section 1.5 of the ABRSM Grade 5 Music Theory exam tests your knowledge of grouping rests. You’ll be given a piece of music with rests and asked to tick or cross each box to show whether the rests are correct or incorrect.
At first glance, these questions can seem tricky. But once you understand a few key principles, they become much easier to tackle.
Here’s everything you need to know.
What Do Section 1.5 Questions Look Like?
You’ll see a short piece of music in a given time signature, with rests marked in certain bars. Your job is to decide whether each rest is grouped correctly.
The key principle: rests should reflect the underlying beat structure of the time signature.
General Principle 1: Show the Beat Subdivision
When grouping rests within a beat, always show the subdivision based on the given time signature.
Example 1: 4/4 Time
In 4/4 time, we expect four crotchet beats per bar.
Let’s look at a bar where something is wrong.
The Problem: A dotted quaver + two demisemiquavers takes up one crotchet beat. But instead of combining the rest into a single semiquaver rest, the rest has been subdivided unnecessarily.
The Rule: Rests should be as close to the original beat unit (a crotchet) as possible. It’s unnecessary to subdivide the rest further.
Verdict: ❌ Cross (incorrect)
Example 2: Triplet in 4/4
Now let’s look at a bar containing a triplet.
The Situation: A triplet beat takes up one crotchet but is divided into three quavers.
The Rule: When dealing with triplets, think of it like compound time – the notes are divided into three. The rest should reflect this subdivision.
Why This Works: The quaver rest reflects the subdivision of quavers within the triplet group.
Verdict: ✅ Tick (correct)
The Triplet Exception
There’s an exception to the general principle. For triplets, the first two beats can commonly be grouped into one rest.
In the example, a more common/modern way of grouping would be to combine the two quaver rests into one crotchet rest.
Important: This only applies if the first two beats are silent. If the last two beats are silent, you can’t apply this exception.
Example 3: Wrong Order of Rests
Now let’s look at a bar with a semiquaver note, a quaver rest, and a semiquaver rest.
The Problem: The order is wrong.
The Rule: Work out the largest subdivision of the beat first. In 4/4, the largest subdivision of a crotchet is a quaver.
So:
- Complete the first quaver: semiquaver note + semiquaver rest
- Then complete the crotchet beat: quaver rest
The Correct Grouping: Semiquaver rest first, followed by quaver rest.
Verdict: ❌ Cross (incorrect)
General Principle 2: Fill Half a Bar with One Rest
In duple or quadruple time, if half the bar is silent, you can group the rests into one combined rest.
Example: 12/8 Time
In 12/8, we expect four dotted crotchets per bar.
The Situation: The first two dotted crotchets are completely silent.
The Rule: If either half of the bar is empty in duple or quadruple time, use one combined rest.
The Solution: Two dotted crotchet rests can be grouped into one dotted minim rest.
Quick Tip: Working with Dotted Rests
If you find dotted rests tricky, here’s a simple way to think about it.
Two Crotchets = One Minim
- Add a dot to each crotchet → you get a dotted minim
- Both add up to three crotchets long
Two Quavers = One Crotchet
- Add a dot to each quaver → you get a dotted crotchet
- Both add up to three quavers long
Two Semiquavers = One Quaver
- Add a dot to each semiquaver → you get a dotted quaver
- Both add up to three semiquavers long
Applying This: Two dotted crotchets = one dotted minim rest (the correct answer for half a bar of silence in 12/8).
Common Pitfalls to Avoid
- Subdividing rests unnecessarily. Rests should be as close to the beat unit as possible.
- Getting the order wrong. Always complete the largest subdivision first.
- Forgetting the triplet exception. Triplets are special – the first two beats can be combined.
- Not grouping half-bar silences. In duple/quadruple time, half a bar of silence = one combined rest.
How Many Marks Is This Worth?
The grouping of rests section is worth only 3 marks out of 75 in the exam. While it’s important to get these marks, don’t stress too much if you find it challenging. The more exercises you do, the more familiar you’ll become with the topic.
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 rest grouping 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.
