Notes de leçon

Starting from a brief

  • Read a supplied brief for its purpose, performers, audience, duration and other actual constraints. For free composition, define an intention within the board’s rules. Do not assume all GCSE boards have identical durations, documentation or assessment instructions.
  • Start with a motif, rhythm, harmony, improvisation or sound, then test it. A provisional structure can support direction but can change as material develops. The fictional practice task in the table is not an assessed submission or official board brief.

Melody writing

  • A motif is a short recognisable idea; a phrase is a shaped musical unit rather than a fixed four-bar sentence. Repetition, diatonic sequence, variation and extension offer different forms of development. Question-and-answer relationships may be unequal in length and need not use identical material.
  • In the written C-major model, C4–D4–E4–G4 in crotchets becomes D4–E4–F4–A4 in a diatonic sequence. The interval sizes adjust to the scale, unlike exact semitone transposition. A climax depends on perceived intensity rather than requiring the highest note. Check both range and tessitura for the actual performer.

Harmony and bass

  • In some tonal styles, I, IV, V and vi offer familiar resources; other chords, modes or pitch organisations may better suit a different intention. Try a harmonic sketch, hear the result and revise the melody or harmony rather than forcing every note into a predetermined chord.
  • A bass line is the lower-register line and can be melodic. Inversions change the bass without necessarily changing the chord identity. A pedal sustains or repeats a pitch through changing harmony and can occur outside the bass. Cadences can shape tonal phrase endings but are not compulsory in every style.

Structure

  • Choose a structure suited to the intention: binary, ternary, verse–chorus, a developing continuous form or another plan. An introduction, bridge or coda is optional rather than a checklist that every composition must include.
  • Repetition can establish relationships; variation develops recognisable material; contrast can articulate a difference. Music based partly on chance can still have structure, so random-note material is not automatically formless. Evaluate the actual organisation.

Texture and instrumentation

  • Allocate musical roles and consider how lines interact, not just how many instruments play. Plan register, balance, entrances, articulation, dynamics and changes of density in relation to the intention.
  • Test parts with their intended performers or appropriate reliable guidance. Range limits alone do not guarantee idiomatic writing: breath, fingering, bowing, leaps, tessitura and available technology may matter. Computer playback can conceal practical difficulty.

Tools

  • Notation software edits a score and may offer playback. DAWs can record, arrange, edit and mix audio or MIDI. MIDI communicates events and controls rather than carrying the recorded audio signal; a sound generator produces audio from those events.
  • Loops, recordings, a metronome and improvisation can all support composing. Keep drafts and document which materials and tools you used in accordance with the actual assessment rules, including any externally supplied material. Tool use does not itself guarantee musical quality or authenticity.

Evaluating

  • Evaluate how the music responds to the intention or supplied brief, how ideas develop, and how resources are handled. Compare a passage before and after a targeted change, then keep or revise the change for a musical reason.
  • Keep an accurate score, recording and supporting documentation as required by the current qualification. This lesson supplies written planning sketches and techniques, not a completed assessed composition, a universal submission checklist or a guarantee of marks.
