If your child moved smoothly through AMEB Grades 1 to 3 theory, Grade 4 can come as a genuine shock — and not for the reason most families expect. It isn't that any single topic is impossibly hard. It's that Grade 4 is the first grade that stops testing skills one at a time and starts asking students to combine them. Up to Grade 3, the exam rewards students who have learned their scales, their intervals, and their rhythm rules as separate boxes to tick. At Grade 4, those boxes start merging into one demanding skill: writing music.This is the grade where harmonisation appears for the first time. It's where modulation, augmented and diminished intervals, the alto clef, and an entire new body of general knowledge all arrive at once. If you understand what changes here — and prepare for it deliberately — Grade 4 is very manageable. If you treat it like "Grade 3 but harder," it has a way of catching students out.This guide breaks down exactly what AMEB Theory of Music Grade 4 tests, how the marks are distributed, what's brand new at this grade, and where students most often lose points.<img src="https://ezycourse.b-cdn.net/2442/cmqrkg76hj7j8j6pld1ro7mgg.jpeg" alt="image" containerstyle="position: relative; width: 205px; height: auto; cursor: pointer;" wrapperstyle="display: flex;"><hr><h2 id="bdd5a275-17dd-46b2-a16a-7bd0af1dbe50" data-toc-id="bdd5a275-17dd-46b2-a16a-7bd0af1dbe50" style="text-align: left; font-size: 24px; line-height: 1.2;">What Is AMEB Music Theory Grade 4?</h2>AMEB Music Theory is a written examination offered by the Australian Music Examinations Board. The theory ladder runs from Grade 1 through Grade 6 and beyond. Grade 4 sits squarely in the middle — the bridge between the foundational grades and the senior theory of Grade 5.The exam is sat online through the AMEB SCORE portal. There are no fixed exam dates and no exam season: students enrol whenever they choose and receive twelve months of unlimited access to practice exams. When a student feels ready, they begin the official exam from within their SCORE account. For families studying AMEB Grade 4 music theory online, this structure is a real advantage — the deadline is the student's own readiness, not a term-based cut-off forcing a premature sitting.Grade 4 is a 100-mark, computer-based exam. Its shape is noticeably different from Grade 3, and understanding that shape is the first step in preparing for it.MusoLearn is not affiliated with AMEB, ABRSM, or Trinity Guildhall.<hr><h2 id="562aea80-7acc-45e8-bc5a-30713816395a" data-toc-id="562aea80-7acc-45e8-bc5a-30713816395a" style="text-align: left; font-size: 24px; line-height: 1.2;">What the Exam Actually Tests</h2>Here is the full mark allocation for AMEB Theory of Music Grade 4:<table style="min-width: 50px;"><colgroup><col><col></colgroup><tbody><tr><th colspan="1" rowspan="1">Topic area</th><th colspan="1" rowspan="1">Marks</th></tr><tr><td colspan="1" rowspan="1">Harmony (writing, cadences + harmonisation)</td><td colspan="1" rowspan="1">22</td></tr><tr><td colspan="1" rowspan="1">Keys and scales</td><td colspan="1" rowspan="1">12</td></tr><tr><td colspan="1" rowspan="1">Time and rhythm</td><td colspan="1" rowspan="1">11</td></tr><tr><td colspan="1" rowspan="1">Intervals (including inversions)</td><td colspan="1" rowspan="1">10</td></tr><tr><td colspan="1" rowspan="1">Creative melody writing</td><td colspan="1" rowspan="1">10</td></tr><tr><td colspan="1" rowspan="1">Transposition</td><td colspan="1" rowspan="1">10</td></tr><tr><td colspan="1" rowspan="1">General knowledge — Baroque suite</td><td colspan="1" rowspan="1">9</td></tr><tr><td colspan="1" rowspan="1">General knowledge — string instruments</td><td colspan="1" rowspan="1">9</td></tr><tr><td colspan="1" rowspan="1">Modulation and terminology</td><td colspan="1" rowspan="1">7</td></tr><tr><td colspan="1" rowspan="1">Total</td><td colspan="1" rowspan="1">100</td></tr></tbody></table>Two things stand out the moment you see this laid out.Harmony is the single largest block — nearly a quarter of the exam. At Grade 3, chords and cadences were worth 18 marks, but the writing task stopped at individual cadences. At Grade 4 the harmony block grows to 22 marks and now includes a full melody to harmonise. We'll come back to this section, because it's where the most marks are won and lost.General knowledge has exploded. At Grade 3, general knowledge was worth just 4 marks. At Grade 4 it is 18 — the Baroque dance suite (9 marks) and string instruments (9 marks), both entirely new. That is more than a fourfold jump, and it represents the most learnable marks in the whole paper.Everything else — scales, rhythm, intervals, melody writing, transposition — carries forward from earlier grades but with harder content layered on top.<hr><h2 id="7c82456d-4643-44f1-99c1-af3e65b974a1" data-toc-id="7c82456d-4643-44f1-99c1-af3e65b974a1" style="text-align: left; font-size: 24px; line-height: 1.2;">What's New at Grade 4 — The Tipping Point</h2>This is the part most students and parents underestimate. A surprising amount of Grade 4 content has never appeared in any earlier AMEB theory exam. Here's what arrives for the first time:<ul><li>Harmonisation — writing four-part harmony to a given melody, not just naming or completing single chords. This is the headline new skill of Grade 4.</li><li>Modulation — recognising when a passage changes key (to the dominant or relative keys) and identifying the new key.</li><li>Augmented and diminished intervals, plus interval inversions — intervals are no longer just major, minor, and perfect.</li><li>Imperfect and interrupted cadences — perfect and plagal cadences were covered at Grade 3; Grade 4 adds the imperfect (ending on chord V) and interrupted (V to VI) cadences.</li><li>The alto clef — a third clef, centred on middle C, used nowhere else in the MusoLearn levels.</li><li>Double sharps and double flats, and major scales up to six sharps.</li><li>Syncopation and hemiola — rhythmic devices that deliberately push against the underlying beat.</li><li>The Baroque dance suite and the string family — two substantial new general-knowledge topics.</li></ul>The alto clef is a good example of why Grade 4 trips students up. It looks unfamiliar because it is unfamiliar — middle C sits on the centre line rather than below or above the staff, and students who have only ever read treble and bass clef have to retrain their eyes.<img src="https://ezycourse.b-cdn.net/2442/cmqrkhjfnj9ysn2pg8aty5aai.png" alt="image" containerstyle="width: 100%; height: auto; cursor: pointer; " wrapperstyle="display: flex">The alto clef — new at Grade 4, with middle C on the centre line. A C major scale, ascending.None of these topics is unreasonable on its own. The challenge is the sheer breadth: a student preparing for Grade 4 is learning more genuinely new material than at any grade since they started.<hr><h2 id="9d664cea-f908-47c4-bff7-925815dfbfa4" data-toc-id="9d664cea-f908-47c4-bff7-925815dfbfa4" style="text-align: left; font-size: 24px; line-height: 1.2;">Harmony — 22 Marks, and Why It Decides the Grade</h2>The harmony block is the defining section of Grade 4, and it comes in three parts:<ul><li>Naming the key, chord, or cadence (2 marks) — identifying what's happening in a given passage.</li><li>Writing the cadence (8 marks across two cadences) — supplying the chords for a cadence point, now including the new imperfect and interrupted cadences.</li><li>Harmonising the melody (12 marks) — the big one. Students are given a melody and must write three lower voices beneath it to create complete four-part harmony.</li></ul>That 12-mark harmonisation question is the highest-value single question in the entire Grade 4 paper. It's also, consistently, the hardest chapter for students at this level — more so than cadences, intervals, or scales.<img src="https://ezycourse.b-cdn.net/2442/cmqrki6z3k1tq32pm6oe1cvuk.png" alt="image" containerstyle="width: 100%; height: auto; cursor: pointer; " wrapperstyle="display: flex">A worked Grade 4 harmonisation in four-part vocal style — the melody harmonised with three lower voices and analysed with Roman numerals.At Grade 4, harmonisation is written in four-part vocal style only — soprano, alto, tenor, and bass voices, with no piano-style option. (Piano style doesn't enter the picture until Grade 5, and even then only for specific cadence questions.) The marking is unforgiving in a particular way: choosing the right chords isn't enough. Voice-leading faults — parallel fifths, parallel octaves, incorrect doubling, an unresolved leading note — cost marks chord by chord, even when the harmonic choices are correct. A student who writes the right progression with poor voice leading will still bleed marks across the question.Because of that, harmonisation rewards a step-by-step method over guesswork: identify the implied chords first, choose your cadences, then write the inner voices while watching for parallels. We cover the full approach in our dedicated guide to <a target="_blank" href="https://www.musolearn.com/en/blog/ameb-music-theory-harmonisation-a-step-by-step-guide-for-grades-4-and-5/">AMEB music theory harmonisation</a>, which applies to both Grade 4 and Grade 5.<hr><h2 id="85466808-98ba-4542-81bf-20a940eed353" data-toc-id="85466808-98ba-4542-81bf-20a940eed353" style="text-align: left; font-size: 24px; line-height: 1.2;">The General Knowledge Surprise — 18 Marks</h2>If harmony is where students lose marks, general knowledge is where they should be banking them — and too many leave it until the last week.At Grade 4, general knowledge jumps from 4 marks to 18, split evenly between two new topics:The Baroque dance suite (9 marks). Students need to know the standard dances of a Baroque suite, their characteristic tempo, metre, and mood, and the ornamentation typical of the period. Questions ask students to identify dance types, describe their character, and recognise their rhythmic and metrical features.String instruments (9 marks). The orchestral string family — violin, viola, cello, and double bass — including their ranges, how they are tuned, the clefs they read, and the technical terms associated with string playing.Here's the important point: this content is factual. There is no voice leading to get wrong, no melody to compose. A student who studies the Baroque suite and the string family methodically can score close to full marks on 18% of the exam. Leaving it to a single revision session in the final week is one of the most common — and most avoidable — Grade 4 mistakes.<hr><h2 id="d2d050bb-1d06-40a5-a705-0477987d907a" data-toc-id="d2d050bb-1d06-40a5-a705-0477987d907a" style="text-align: left; font-size: 24px; line-height: 1.2;">Where Students Lose Marks at Grade 4</h2>A handful of patterns account for most lost marks:<ul><li>Harmonisation voice leading. Right chords, wrong voice leading. Parallel fifths and octaves are the classic culprits. This is a technique that has to be practised and ideally marked by a teacher, because students rarely spot their own parallels.</li><li>Treating general knowledge as an afterthought. Eighteen learnable marks left on the table because the Baroque suite and string instruments weren't studied until the end.</li><li>Alto clef unfamiliarity. Students misread notes simply because they haven't spent enough time with a clef they'll see nowhere else.</li><li>Ignoring modulation. Because it's worth fewer marks (bundled into a 7-mark section with terminology), modulation often gets skipped in preparation — then costs easy points on exam day.</li></ul>There's also a real-world reason Grade 4 theory matters beyond the theory exam itself. From Grade 6 onwards, AMEB practical exams require a theory pass as a co-requisite — and the requirement is theory two grades below the practical grade. Grade 4 theory is the co-requisite for Grade 8 practical. A student working towards a high practical grade will need this pass on record, so it's worth getting it done properly rather than rushed.<hr><h2 id="a37e8fe9-0498-4dfa-9eab-a5525799577a" data-toc-id="a37e8fe9-0498-4dfa-9eab-a5525799577a" style="text-align: left; font-size: 24px; line-height: 1.2;">How to Prepare for AMEB Grade 4 Music Theory</h2>A structured approach beats a scattergun one at this grade, precisely because there's so much new material:<ol><li>Map the new content first. Identify which topics are genuinely new to you (harmonisation, modulation, alto clef, aug/dim intervals, the Baroque suite, strings) and give them the most time. The carried-over topics need revision; the new ones need teaching.</li><li>Bank the general knowledge early. Study the Baroque suite and string instruments in the first half of your preparation, not the last week. These are reliable marks.</li><li>Practise harmonisation with feedback. This is the one section you can't reliably self-mark — voice-leading faults are easy to miss in your own work. Have harmonisation exercises checked and annotated by a teacher.</li><li>Use the practice exams. Once enrolled, students get twelve months of unlimited practice exams through AMEB SCORE, in the same format and interface as the real thing. Using them extensively is one of the most effective ways to revise content and remove exam-day surprises.</li><li>Work in short, regular sessions. Ten to fifteen minutes a day of focused theory beats an occasional long cram — especially for a grade with this much new material to absorb.</li></ol>MusoLearn is not affiliated with AMEB, ABRSM, or Trinity Guildhall.<hr><h2 id="f9d1270e-fb89-466b-a401-ea0d930e5acd" data-toc-id="f9d1270e-fb89-466b-a401-ea0d930e5acd" style="text-align: left; font-size: 24px; line-height: 1.2;">How MusoLearn Level 4 Prepares You</h2><a target="_blank" href="https://www.musolearn.com/en/course-detail/music-theory-level-4/6170/">MusoLearn Level 4</a> is a structured video course covering the full AMEB Grade 4 theory syllabus across 10 chapters and 24+ short lessons.
