Interleaving
Mix topics in one session — don’t block them.
What the Research Says
Most students revise by blocking — an hour on one set work, an hour on another. It feels productive and the topic seems clear by the end. Interleaving is the opposite: you jump between set works or question types inside a single session. It feels worse at the time, and you’ll make more mistakes. But when the real exam arrives, you will be dramatically better at knowing which set work a listening extract belongs to — and that is usually the hardest part of the unseen listening questions.
Evidence Base
| Study | Finding | Impact |
|---|---|---|
| Rohrer & Taylor (2007) | Students who interleaved topics scored 43% higher on delayed tests than blocked-practice students. | Same time spent — huge difference in exam performance. |
| Birnbaum et al. (2013) | Interleaved learners felt LESS confident during practice but performed BETTER in the test. | If revision feels too easy, interleave. |
| Bjork & Bjork (2011) | Desirable difficulties — including interleaving — create durable long-term learning at the cost of short-term performance. | Short-term struggle is the price of long-term gain. |
| Taylor & Rohrer (2010) | Benefit was largest when topics looked superficially similar — students learnt to DISTINGUISH them. | Most useful where students confuse similar techniques. |
Step-by-Step Method
- 1Pick 3–5 related set works — works that appear on the same paper or share a genre. Similar enough that students might confuse them.
- 2Make a mixed question set — 10–15 questions drawn randomly from all the works. Don’t label which work each question belongs to.
- 3Attempt each question cold — first step is identifying which work is being asked about. That identification is the skill you’re training.
- 4Mark after every question — note which work each one was. Pay attention to mis-identifications — those are the highest-value gaps.
- 5Rebuild a new mixed set tomorrow — same works, different questions, different order. Over time, mis-identifications drop.
- 6Expect to feel worse than blocked practice — that’s the right feeling. Your exam self will thank you.
Write 15 questions mixing details from Haydn Symphony No.94 ‘Surprise’, Movement 2 (Western Classical L4), Mozart Clarinet Concerto K.622, Movement 3 (Western Classical L3), and Chopin: Nocturne in E-flat major, Op.9 No.2 (Western Classical L6). Shuffle them and attempt cold — forcing yourself to recall which composer, which genre, and which structural features belong to each.
In a single 30-minute session, alternate between score-reading questions (time signatures, clef identification) and set-work recall questions about Verdi: Requiem ‘Dies Irae’ (Western Classical L8). The switch between analytical reading and aural recall trains your brain to manage both question types in the same exam paper.
Common Pitfalls
- Random, not related. Interleaving Music with Maths is just subject-switching. Interleave WITHIN Music — related works or question types that students confuse.
- Giving up when it feels hard. The discomfort is the signal that it’s working. Don’t revert to blocked practice because interleaving feels slow.
- Labelling the set work at the top of each question. Defeats the point — the identification IS the training.
- Using it too early in learning. You need baseline familiarity with each work first. Interleaving is for consolidation, not first exposure.
When to Use This
Once you’ve covered a handful of related set works — usually partway through a term — start weaving them into mixed practice sessions. Very useful in the final 8–10 weeks before exams when you’re moving from learning to applying. Full past papers are the ultimate interleaving exercise, because they force you to switch between listening, score-reading, and set-work questions cold.
