Rhythm, metre and melodic dictation: WACE Year 12 Music
“Notate rhythm and metre, and transcribe melodic and rhythmic dictation accurately as part of aural and theory skills”
Rhythm is notated with note and rest values inside a metre set by the time signature, which is simple when the beat divides into two and compound when it divides into three; melodic dictation is transcribed by fixing the key and metre first, then sketching the contour, then refining pitch and rhythm over repeated hearings; accuracy comes from a consistent method and a final check against the tonic and the bar lines.
What this dot point is asking
SCSA wants you to capture sound as accurate notation at speed. Dictation is one of the highest-value aural skills in the paper, and it rewards a reliable, repeatable method far more than raw talent.
Note values and metre
Note values halve at each step: semibreve, minim, crotchet, quaver, semiquaver, with matching rests. A dot after a note adds half its value again, so a dotted crotchet equals a crotchet plus a quaver.
The time signature sets the metre. The top number gives beats per bar; the bottom number gives the beat unit.
- Simple time (2/4, 3/4, 4/4) has a beat that divides into two equal halves.
- Compound time (6/8, 9/8, 12/8) has a beat that is a dotted note dividing into three. In 6/8 there are two dotted-crotchet beats per bar, not six.
Beaming groups notes to show the beat clearly: quavers and smaller notes are beamed within a beat so the reader sees the pulse at a glance.
If the beat naturally splits into two ("1-and, 2-and") the metre is simple; if it splits into three ("1-and-a, 2-and-a") it is compound. This single judgement decides whether you write 3/4 or 6/8 for what might sound similar.
Melodic dictation: the method
A consistent procedure prevents panic and lost marks:
- Before the first playing, write the clef, key signature and time signature, and note the starting pitch given.
- On the first hearing, listen for the overall shape and the metre. Do not write notes yet; feel the pulse and count the bars.
- On the next hearing, sketch the contour with rough noteheads or arrows for up and down movement, marking where leaps occur.
- Refine pitch using the key: relate each note to the tonic and the scale degrees, and check leaps as intervals.
- Add rhythm by subdividing each beat, lining up note values with the pulse you counted.
- On the final hearing, check the tonic, the bar lines and that each bar adds up to the correct number of beats.
Rhythmic dictation
For rhythm-only dictation, tap or count the steady beat first, then place each sound within the beat. Decide the metre early, then work bar by bar. Watch for dotted rhythms, syncopation (accents off the beat) and triplets (three notes in the space of two). Confirm every bar totals the value the time signature demands before moving on.
Step 1: count the steady beat first
Establish the pulse in and count "1, 2, 3, 4" steadily before judging any rhythm. The bar you hear sounds like "long, short-short, long, rest".
Step 2: subdivide each beat into quavers
Mentally divide each crotchet beat into two quavers ("1-and, 2-and, 3-and, 4-and") and place each sound on the grid. The "long" sits on beat 1, the "short-short" fills beat 2 as two quavers, the next "long" sits on beat 3, and beat 4 is silent.
Step 3: convert to note values
The first long is a crotchet, the short-short is two quavers, the next long is a crotchet, and the silence is a crotchet rest: crotchet, two quavers, crotchet, crotchet rest.
Step 4: check the bar totals
Add the values: crotchet beats. The bar fills exactly, so it checks out before you move on.
Using key and tonic to fix pitch
The most common pitch errors come from drifting away from the key. Anchor every phrase to the tonic: hum the tonic between hearings, identify whether a note is a scale degree or a chromatic note, and treat leaps as named intervals rather than guesses. If a melody ends on the tonic, that is a strong checkpoint that the rest is in tune with your transcription.
Why this matters for the exam
Dictation marks are awarded for pitch and rhythm accuracy bar by bar, so a methodical transcription that gets most bars exactly right beats a rushed one that is roughly correct everywhere. Practising little and often, with a focus on hearing intervals against the tonic and subdividing the beat, builds the speed the exam demands.
- Writing 6/8 as simple time
- Six quavers in a bar grouped in twos is 3/4; grouped in threes with two dotted-crotchet beats it is 6/8.
- Starting to notate notes on the first hearing
- Spend the first playing on shape and metre, then fill in detail, or you will lock in early errors.
- Letting pitch drift from the key
- Re-anchor to the tonic frequently and check the final note.
- Bars that do not add up
- Always total each bar against the time signature before moving on.
Exam-style questions
Questions in the style of SCSA exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
WACE 2022-style8 marksMelodic dictation: the melody is in G major and begins on the given note. It will be played a set number of times. Notate the four-bar melody with correct pitch and rhythm. State the metre you have identified and justify it.Show worked answer →
Work to a fixed procedure rather than writing notes on the first hearing.
Setup: write the treble clef, the G major key signature (one sharp) and leave the time signature until you have judged the metre. Note the given starting pitch.
First hearing: judge the metre and overall shape. If the beat divides into two it is simple (, , ); into three it is compound (, ). Justify: "each beat divided into two equal halves, so simple quadruple, ."
Middle hearings: sketch the contour, then refine pitch by relating each note to the tonic G and reading leaps as named intervals (a leap from G up to D is a perfect fifth).
Rhythm: subdivide each beat into quavers and line up the values; check every bar totals four crotchet beats.
Final hearing: confirm the tonic and bar lines. Markers award pitch and rhythm separately, bar by bar, so an accurate transcription of most bars beats a rushed roughly-right one.
WACE 2021-style5 marksRhythmic dictation: notate the two-bar rhythm in . The recording is played several times. Then explain one feature that confirms the metre is compound rather than simple.Show worked answer →
In there are two dotted-crotchet beats per bar, each dividing into three quavers, so think in two groups of three, not six even quavers.
Tap the two main beats and place each sound within its group of three. A common figure is a dotted crotchet (a full beat) followed by a beat of three quavers, or quaver-quaver-rest patterns; watch for these. Confirm each bar totals six quaver-values.
Feature confirming compound: the beat subdivides into three ("1-and-a, 2-and-a"), and the natural grouping and beaming fall into threes. Markers reward correct beaming into the two dotted-crotchet beats; beaming six quavers in twos would wrongly imply .
