Eduqas GCSE Music: Film Music (Area of Study 3) - purpose, diegetic and non-diegetic sound, leitmotif, the elements and composing to picture

What this area covers

This area is Area of Study 3, Film Music, which is about how music supports a moving image. It is tested in the Component 3 appraising exam, with two questions, using recorded extracts. The area covers the purpose of film music, diegetic and non-diegetic sound, leitmotif and thematic writing, how the elements create mood and action, and composing to picture. Unlike a concert work, film music serves the picture, so every question comes back to purpose and effect.

This guide ties together the five dot-point pages for the area.

The purpose of film music

Film music exists to support the moving image. Its purposes are to set the mood and atmosphere, support the action and pace, establish time and place, signal character and emotion, and guide how the audience feels. Most film music is the underscore (background scoring, usually non-diegetic); title music sets the tone over the credits.

Diegetic and non-diegetic music

Diegetic (source) music comes from within the scene and the characters can hear it (a radio, a band). Non-diegetic music is for the audience only and the characters cannot hear it (the underscore, the title music). The test is "can the characters hear it?". Composers can blur the line for effect, for example when source music swells into underscore.

Leitmotif and thematic writing

A leitmotif is a recurring musical idea that represents a character, place, object or idea. It returns whenever that thing is present and can be transformed (in key and mode, tempo, dynamics, instrumentation, texture and register) to track the drama. Recurring themes unify the score and signpost the action, sometimes before a character appears.

Film music and the elements

The elements create mood and action: melody (lyrical for calm, leaping for heroic, fragmented for tense), harmony and tonality (consonant major for warmth, minor or dissonant for darkness), rhythm and tempo (slow for calm, fast or an ostinato for action), dynamics (soft for suspense, loud for power, crescendos and stabs), texture (thin for intimacy, thick for grandeur) and instrumentation (strings and flute for tenderness, brass and percussion for action).

Composing for a moving image

To compose to picture, identify the hit points (key moments) and time the music to land on them, change the elements with the action, and choose the elements for each section's mood. One of the four Eduqas composing briefs (Component 2) is usually a film brief, so the listening skills here feed straight into composing. Confirm the current briefs with your centre.

How to revise this area

1. Always link music to effect. Name the purpose and say what the music does for the scene and the audience.
2. Learn the diegetic test. Ask "can the characters hear it?" to decide diegetic or non-diegetic, and watch for blurring.
3. Master the leitmotif. Define it as a recurring idea standing for something, and describe transformation in elemental terms.
4. Drill the elements for mood. Practise saying how tempo, harmony, dynamics, texture and instrumentation create calm, tension and action.
5. Think like a film composer. Mark hit points, time the music to them, and justify every choice by its effect.
