What this dot point is asking
SEAB wants you to write a singable, well-shaped melody: one with balanced antecedent and consequent phrases, a clear melodic shape and range, a unifying motif, and a satisfying cadential ending. The central insight is that a good melody is planned, not improvised note by note: you design its phrasing and shape, build it from a recurring idea, and steer it to a convincing close.
The answer
Balanced phrasing: question and answer
A melody should breathe in balanced phrases, most simply as a four-bar antecedent (a musical question, ending open and unresolved) answered by a four-bar consequent (an answer, ending with closure). The antecedent typically rests on the dominant (or another open note), and the consequent comes home to the tonic, giving the melody a satisfying question-and-answer logic.
A clear shape and range
A memorable melody has a clear contour: often rising to a high point (the climax), then falling to the final note. Keep the range comfortable for the chosen voice or instrument (roughly an octave or a little more for a beginner melody) and move mostly by step (conjunct), using a few leaps for expression and interest, with leaps usually balanced by stepwise motion afterward.
A unifying motif
Build the melody from a short, distinctive motif, a few notes or a rhythm introduced at the start, then reuse and vary it: repeat it, sequence it higher or lower, or invert it. Threading the motif through the tune gives it identity and unity, so it sounds purposeful rather than rambling.
A convincing ending
End on a strong, conclusive note, normally the tonic on a strong beat, approached by step or from the leading note so the close feels like a perfect cadence. A melody that simply stops on a weak or unrelated note feels unfinished.
Examples in context
Example 1. A folk-song melody. Many folk tunes are model melodies: two balanced phrases in question-and-answer form, a comfortable singable range, a clear arch shape, and a simple recurring motif, ending firmly on the tonic. Studying such a tune shows every principle of good melody writing in miniature.
Example 2. A Classical theme that is then varied. A Classical theme used for variations is deliberately clear and balanced, with a memorable motif and tidy phrasing, precisely so it can be recognised when reworked. It demonstrates how a strong, well-shaped melody provides material that can be developed.
Try this
Q1. Explain the difference between an antecedent and a consequent phrase. [2 marks]
- Cue. The antecedent is the opening phrase that poses a question and ends open (often on the dominant); the consequent is the answering phrase that ends with closure on the tonic.
Q2. Describe two ways to develop a motif within a melody. [2 marks]
- Cue. Repeat it, sequence it at a higher or lower pitch, invert it, or vary its rhythm (any two), so it recurs while staying recognisable.
Q3. Explain how to make a melody's ending sound convincing. [2 marks]
- Cue. End on the tonic on a strong beat, approached by step or from the leading note, so the close has a perfect-cadence feel of completion.

Original8 marksDescribe, in words, how you would compose an eight-bar melody in C major in time for a flute, using balanced phrasing, a clear shape and a unifying motif, and ending convincingly.Show worked answer →
Plan the phrasing first. Write the melody as two four-bar phrases that balance like a question and answer: an antecedent (the question) ending on an open, unfinished note (for example resting on the dominant, G), and a consequent (the answer) ending firmly on the tonic, C.
Create and use a motif. Invent a short, memorable rhythmic-melodic idea (a motif) in the first bar, then reuse and vary it across the melody (repeated, sequenced higher, or inverted) so the tune is unified rather than rambling.
Shape the line. Give the melody a clear contour, for example rising to a high point (climax) near the start of the second phrase, then falling to the final note, and keep the range comfortable for a flute (roughly an octave or a little more) and mostly conjunct with a few expressive leaps.
End convincingly. Make the last two bars feel like a perfect cadence: approach the final tonic by step or from the leading note, landing on C on a strong beat.
What markers reward: balanced antecedent and consequent phrases, a clear shape and sensible range, a motif that recurs and is developed, and a convincing cadential ending on the tonic. The strongest answers vary the motif (sequence or inversion) rather than merely repeating it.
Original6 marksExplain the terms antecedent phrase, consequent phrase and motif, and describe how each helps make a melody coherent.Show worked answer →
Antecedent phrase: the opening phrase that poses a musical question, usually ending on an open, unresolved note (such as the dominant) so the listener expects more.
Consequent phrase: the answering phrase that responds to the antecedent and ends with a sense of closure, usually on the tonic, completing the idea.
Motif: a short, distinctive musical idea (a few notes or a rhythm) that recurs through the melody, often varied, giving it identity and unity.
How they help coherence: the antecedent and consequent give the melody balance and a satisfying question-and-answer logic; the motif threads through the whole tune so it sounds unified and memorable rather than a string of unrelated notes.
What markers reward: correct definitions of all three and a clear account of how balanced phrasing and a recurring motif create coherence. The strongest answers note that the antecedent feels open and the consequent feels closed, like a question and its answer.
