What does the Composing module cover at N(A)-Level?

It covers the creating skills for the coursework: writing a simple, singable melody with clear phrases; harmonising it with the primary chords (I, IV and V) and placing a cadence; turning chords into a supportive accompaniment such as broken chords, a riff or a bass line; and planning a short complete piece from a brief with a clear structure, contrast and a satisfying ending. In the SEAB Creating and Performing coursework, creating sits alongside performing, so your composed and arranged work is assessed as practical music-making.

How do I write a simple melody for N(A)-Level?

Choose a key and a comfortable range, then write two balanced phrases that work like a question and an answer (antecedent and consequent). Move mostly by step with only a few leaps so it is singable, give it a clear shape such as an arch, and end on the tonic so it sounds finished. Keeping it simple and singable scores better than crowding in difficult ideas.

Which chords should I use to harmonise a melody?

Start with the three primary chords, I, IV and V, which can harmonise most simple tunes. Match each chord to the melody note it shares (for example a melody C can sit over chord I or chord IV in C major), change chords at a sensible rate (the harmonic rhythm should not be too fast), and place a perfect cadence (V to I) at the end of the phrase so it closes well.

How do I turn chords into an accompaniment?

Take the chords you chose and play them as a pattern rather than as plain blocks. Common choices are broken chords (arpeggios) that spread the notes out, a repeating riff or ostinato, or a bass line that moves with the harmony. Keep the accompaniment simpler and lower in the texture than the tune so it supports the melody rather than competing with it.

How does the Composing module connect to the rest of the course?

Composing uses the scales, chords and cadences from the Elements of Music and Notation module, and the structures (ABA, verse-chorus) from the Listening and Analysis module. Listening widely across the Areas of Study gives you ideas and models, and what you compose can feed your performing. In the coursework, creating and performing are assessed together, so the skills reinforce one another.

What the Composing module demands

Composing is part of the Creating and Performing coursework, where you make and shape your own music rather than answer questions about someone else's. SEAB rewards clear, controlled musical ideas: a singable melody, harmony that fits, an accompaniment that supports, and a short piece with a sensible shape. The watchword at N(A)-Level is keep it simple and do it well. This guide ties the four dot points together and links to each.

The four creating skills are writing a simple melody, adding chords to a melody, creating rhythm and accompaniment, and planning a short piece.

Writing a melody

A good composition starts with a good tune. The page on writing a simple melody shows how to choose a key and range, build two balanced question-and-answer phrases, move mostly by step with a few well-placed leaps, give the melody a clear shape, and end on the tonic. A singable melody that one person could hum is worth far more than a complicated line nobody could sing.

Adding harmony

Once the tune exists, harmony makes it richer. The page on adding chords to a melody shows how to harmonise with the primary chords I, IV and V, how to match a chord to the melody notes it contains, how to set a sensible harmonic rhythm (the rate at which chords change), and how to close with a perfect cadence. Choosing fewer chords that fit is better than many chords that clash.

Creating accompaniment

Chords become music when they are given rhythm and movement. The page on creating rhythm and accompaniment shows how to turn block chords into broken chords (arpeggios), a riff or ostinato, or a moving bass line, and how to keep the accompaniment supportive (simpler and lower than the tune) rather than competing with it. The accompaniment should frame the melody, not fight it.

Planning a whole piece

A piece needs a shape. The page on planning a short piece shows how to work from a brief, choose a structure such as ABA or verse-chorus, develop a main idea (motif) so it is not just repeated unchanged, create contrast in the middle, and shape a clear beginning, middle and end with a satisfying close. Unity and contrast together keep a piece both coherent and interesting.

A worked composing walkthrough

Composing a short ABA piece

The brief: compose a short piece in ternary (ABA) form that begins calmly, becomes more energetic in the middle, and returns to calm. Work through it.

Step 1: Plan the structure and mood

Choose C major and a moderate tempo. Section A is calm; section B contrasts by becoming more energetic; section A returns to bring the piece home. Decide A is eight bars, B is eight bars, and A returns.

Step 2: Write the A melody and harmony

Write a gentle eight-bar tune in two phrases that move mostly by step and end with a perfect cadence (V to I). Harmonise with I, IV and V, changing chords about once a bar so the harmonic rhythm is not too fast.

Step 3: Create contrast in section B

For B, raise the energy: use a faster rhythm, a slightly higher range, louder dynamics and a more active accompaniment such as broken chords. Keep it in the same key so the return feels natural, but make it clearly different from A.

Step 4: Return to A and end

Bring back the calm A section so the piece has unity, then finish on the tonic with a clear perfect cadence and a softer dynamic so the ending feels settled. The result has unity (A returns), contrast (B differs) and a satisfying close.

Solutions

Q1: They are two balanced phrases that answer each other: the first phrase (antecedent) sounds like a musical question, often ending unresolved, and the second (consequent) answers it and rounds the idea off, usually ending on the tonic.
Q2: Stepwise movement makes the melody smooth and singable; a few leaps add interest, but too many large jumps make it hard to sing and harder to harmonise.
Q3: The primary chords are I, IV and V. A perfect cadence is chord V to chord I, which sounds finished and so makes a good ending for a phrase.
Q4: Harmonic rhythm is the rate at which the chords change. It should not be too fast because changing chords too often sounds restless and is hard to perform; about one chord per bar (or per strong beat) usually works for a simple piece.
Q5: Any two of: repeat the motif at a higher or lower pitch (sequence); change its rhythm; invert it (turn it upside down); extend or shorten it; or vary its dynamics and articulation. Developing the motif keeps unity while adding interest.
