Hear and describe rhythm, metre and tempo
Distinguish beat, metre, rhythmic pattern and tempo, then describe syncopation, cross-rhythm and changes of pace in context.

Exam scope and assessment notes
Original StudyForA teaching aligned to Cambridge IGCSE Music 0410 and the otherwise-equivalent 9–1 Music 0978 syllabuses for exams in 2026–2028 and 2029–2031. Not Cambridge-authored material, official exam audio, an official mark scheme or an official grade. Practice questions and examples are original. Real aural discrimination requires listening to recordings; live performing, group rehearsal, composition portfolios, centre assessment and Cambridge moderation require a teacher and suitable equipment. Neither qualification is available to private candidates; 0978 is offered only in limited administrative zones. Confirm entry eligibility and the correct examination year with your centre.
Before you begin
- No prior Cambridge Music study is assumed here; start with the notation and listening vocabulary lessons, then follow the areas of study in any sequence that fits your course.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
What makes a music-analysis answer reliable?
What you will learn
- Distinguish simple and compound metre and identify duple, triple, quadruple or irregular grouping
- Describe syncopation, anacrusis, hemiola, cross-rhythm and polyrhythm
- Interpret tempo, BPM, rubato, accelerando and rallentando
Keep beat, metre and rhythm separate
The beat is the pulse; metre groups beats into recurring patterns; rhythm is the pattern of durations and accents. A bar of 3/4 groups three quarter-note beats, while 6/8 usually groups six quavers into two larger beats. The syllabus includes duple, triple, quadruple and irregular metres, and both simple and compound time; the notation and heard grouping both matter.
An anacrusis begins before the first complete bar. Syncopation places emphasis on a normally weak beat or subdivision. Hemiola temporarily makes two groups of three feel like three groups of two, or vice versa. Cross-rhythm and polyrhythm involve contrasting rhythmic patterns; do not use them as interchangeable labels.
The syllabus also names habanera and marcado rhythms, forward and reverse clave, Hindustani tāla, and Arabic īqā’āt (singular īqā’). Learn each pattern in its own context; a time signature alone does not identify the tradition or rhythmic cycle.
Describe pace and change
Tempo is the speed of the beat; BPM gives a numerical rate. Allegro, andante and adagio are common approximate tempo words, but context and style affect the performance.
Accelerando gradually speeds up, rallentando gradually slows down, and rubato flexes timing expressively. A tempo change is not the same as a change in note density: rapid notes can occur over a slow beat.

Pause and explain
Which habit best supports hear and describe rhythm, metre and tempo?
Worked example
In 6/8, a passage has a steady pulse with accents on the first and fourth quavers. Explain the likely grouping.
Show the worked solution
- There are six quavers in each bar.
- The stronger pulses fall on quavers one and four.
- That groups the bar into two dotted-quarter beats, a compound-duple feel.
Answer The accents on quavers one and four create two larger beats, each subdivided into three quavers: a compound-duple feel. The answer describes the accent pattern rather than calling 6/8 simply ‘six beats’.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A 3/4 waltz has accents on beats 1 and 3 for several bars. What should you check before calling it a hemiola?
Give me a hint
Look for a temporary change in grouping, not merely an extra accent.
Compare my reasoning
- Identify the written metre.
- Listen or inspect whether the grouping changes across a phrase.
- Compare the pattern of two groups of three with three groups of two.
A strong beat 3 alone is not enough. Hemiola requires a temporary shift in perceived grouping, commonly two groups of three becoming three groups of two, supported by the accents and phrase.
Look for these in your work
- Uses the time signature
- Distinguishes accent from regrouping
- Defines the hemiola pattern
A track holds the same BPM while the melody changes from long notes to rapid semiquavers. Which musical dimension changes, and which stays steady?
Give me a hint
Separate note density from pulse speed.
Compare my reasoning
- Name the fixed beat rate.
- Describe the change in note durations.
- Avoid describing the new texture as a faster tempo unless the pulse changes.
The tempo stays steady because the BPM is unchanged. The rhythmic surface becomes denser as the melody uses shorter notes. A listener may feel more energy, but that is not by itself a tempo increase.
Look for these in your work
- Keeps BPM constant
- Identifies denser rhythm
- Avoids conflating tempo and note rate
A melody begins with an upbeat, shifts its accents away from the main pulse and ends with a gradual slowing. Describe the three features in exam-ready language.
Give me a hint
Use one accurate term for each event.
Compare my reasoning
- Name the pickup before the first full bar.
- Describe the displaced accents.
- Name the gradual change in tempo.
The melody begins with an anacrusis. Its displaced accents create syncopation, and it ends with a rallentando. These terms describe separate events: entry, accent pattern and tempo change.
Look for these in your work
- Names anacrusis
- Names syncopation
- Names rallentando
Common mistakes
- Calling every fast rhythm a fast tempo
- Treating every unusual accent as a cross-rhythm
- Confusing a gradual rallentando with a sudden pause
What can you explain now?
What is syncopation?
Compare with the explanation
An emphasis on a normally weak beat or subdivision
The displaced accent changes the expected balance of strong and weak pulses.
