Composition and songwriting
What the domain tests
Composition and songwriting in NCEA Level 3 Making Music is assessed through AS91421, where you compose three original pieces. The portfolio asks for finished musical works, not sketches: each piece needs a clear intent, coherent structure, idiomatic writing for the chosen forces, and evidence of development. You may submit audio, a score, a lead sheet or a chord chart; the notation must match what is heard.
Core rules
- Plan form before detail: verse–chorus, 32-bar AABA, through-composed, or a 12-bar frame can all work, but contrast and return must be audible.
- Develop material: repetition, sequence, inversion, rhythmic augmentation or diminution, reharmonisation, textural change.
- Keep harmony, melody, bass and rhythm consistent with the style; avoid accidental clashes and unplayable ranges.
- Document the process and acknowledge collaboration or sampled material.
Worked example
A 4-bar motif in G major uses G–A–B–D over G–D–Em–C. To extend it, keep the rhythm but sequence the motif up a third (B–C–D–F♯) over Em–Bm–C–D; then augment the final two notes and change the texture from block chords to arpeggios. Reasoning: sequence creates forward motion, reharmonisation supports the new pitches, and textural contrast marks a phrase boundary without abandoning the motif.
Traps
- Loop copy-paste with no development.
- Audio and score disagree, or the score omits key parts.
- Writing beyond the performer’s range or idiom.
- Confusing a demo with a completed composition.
