Composition and performance

ZIMSEC O Level · Musical Arts · Form 2, Form 3, Form 4

Composing

  • Start from a rhythm, a melody, a poem or a traditional song.
  • Use repetition and contrast; develop ideas by changing rhythm, pitch or dynamics.
  • Write a simple melody within a key, ending on the tonic (doh) for a feeling of completion.
  • Add accompaniment: chords I, IV and V, drum patterns or an ostinato (a repeated pattern).
  • Use technology: recording apps and notation software.

Performing

  • Prepare: practise regularly, warm up voice or fingers, learn the piece in sections.
  • Perform with accuracy (correct notes and rhythm), expression (dynamics and phrasing), good tone, and stage presence.
  • Ensemble skills: listen to others, follow a leader, keep in time.

Evaluating a performance

Comment on accuracy, tempo, dynamics, balance, tone quality, expression and audience communication.

Arranging

Adapting an existing tune for different voices or instruments (e.g. arranging a folk song for marimba band).

Exam tip: Use musical vocabulary when evaluating: “the dynamics were well contrasted, from piano in verse one to forte in the chorus”.
