Creating and Performing Music: Composition, Arrangement and Performance
What you must know
This domain rewards practical craft. For composition and arrangement, understand motivic development (repetition, sequence, inversion, augmentation, diminution, fragmentation), harmonic planning (diatonic function, pivot chords, cadence placement), rhythmic drive, and idiomatic writing for chosen forces. Know how to produce a score or lead sheet with correct clefs, key and time signatures, transpositions, dynamics, phrasing and articulation, and how to realise a chord chart with appropriate voicings and bass lines.
For performance, understand interpretation: tempo choice, rubato, dynamic shaping, articulation, balance and blend, intonation, and ensemble communication (cueing, breathing, following a conductor). Know rehearsal technique: slow practice, isolation of difficult bars, metronome work, and reflective evaluation against a stated intention.
Traps to expect
- Confusing arrangement with composition. Arranging reworks existing material; claiming new thematic material in an arrangement answer loses marks.
- Transposition errors. A B-flat instrument sounds a major second lower than written; clarinet in A sounds a minor third lower. Check direction, not just interval.
- Notating a motif without its rhythm. Motivic identity includes rhythm and contour; pitch-only answers are incomplete.
- Vague interpretation language. "Play it with feeling" scores nothing; specify where and how ("widen the crescendo across bars 12–16 to peak on the downbeat").
- Ignoring the brief. If the task specifies duration, forces or style, address each constraint explicitly.
Rule of thumb
Every creative or performance decision needs intention plus evidence: say what effect you want and which musical means produce it. "I use augmentation in the bass to slow the harmonic rhythm and heighten tension before the final cadence" is a full-mark sentence.
Worked example
Task: develop a four-note motif into an eight-bar transition. Approach: state the motif (bars 1–2), sequence it up a tone (3–4), invert it over a rising bass (5–6), then augment it to lead into the new key (7–8). Justify each step by the tension it creates, and mark dynamics and articulation so a performer can realise the plan.
