Melody Writing and Notation Conventions - TCE Music (Tasmania)
“Write a melody with clear phrase structure and cadence, and notate pitch and rhythm using correct clefs, stems, beaming, accidentals and bar layout.”
This is two skills in one. Melody writing means inventing a singable line with a clear shape: an opening idea, a balanced answering phrase, a sense of direction towards a high point, and a cadence that closes it. Notation means writing music down so it is unambiguous: correct clef and key signature, stems and beams that follow the rules, accidentals applied correctly, and bars that add up to the time signature. TASC theory tasks reward both a musical line and a clean, readable score.
What this dot point is asking
Shaping a melody
A good short melody usually divides into balanced phrases, often a four-bar antecedent (question) answered by a four-bar consequent (answer). The antecedent ends on an open-sounding chord, typically the dominant, so the ear expects more. The consequent returns and ends on the tonic, closing the idea. This question and answer design gives a melody coherence even before you add harmony.
Contour is the rise and fall of the line. Aim for a single clear high point (a climax) rather than several competing peaks, and approach it gradually so it feels earned. Mix stepwise motion with occasional leaps, and balance a leap by moving back in the opposite direction, which keeps the line singable. Repeat or sequence a small motif so the melody sounds unified rather than random.
The antecedent is the opening phrase that sounds unfinished, usually closing on a half cadence. The consequent is the answering phrase that resolves to the tonic. Together they form a balanced period, the most common building block of a melody.
Cadences and harmonic implication
Even an unaccompanied melody implies harmony. End phrases on notes that suggest a cadence: arriving on the leading note or the second degree implies a dominant (an open ending), while arriving on the tonic implies a perfect cadence (a closed ending). Planning these implied cadences first gives your melody a skeleton to fill in.
Clefs, stems and beaming
Notation has firm conventions. Choose the clef that keeps the notes near the staff: treble for higher instruments and voices, bass for lower. Stem direction depends on the note's position: notes below the middle line have stems up on the right, notes on or above the middle line have stems down on the left. Beam notes together within a beat so the metre is visible, and do not beam across the middle of a bar in a way that hides the main pulse.
The single most common notation error is beaming that obscures the pulse. In simple quadruple time, group quavers and semiquavers within each crotchet beat so a reader can instantly see beats one to four. Clear beaming is worth easy marks and makes a piece sight-readable.
Accidentals, ties and rests
An accidental lasts for the rest of the bar in the octave it appears, and is cancelled by the next barline. Use a courtesy accidental in brackets if a return to the natural could be missed. Tie notes across a barline rather than writing a note value that cannot exist, and use rests to complete every beat so the bar adds up exactly to the time signature. In compound time, group and rest in dotted-beat units, not in simple-time groupings.
Laying out the bar
Every bar must total the value the time signature demands. Space notes roughly in proportion to their length so the eye reads the rhythm at a glance, and align notes that sound together vertically when writing more than one part. Add the time and key signatures at the start, the tempo and any expression marks, and bar numbers or rehearsal marks for longer pieces.
Step 1: Assign each beat
You want crotchet, two quavers, crotchet, crotchet in 4/4. Beat one is a single crotchet; beat two is two quavers; beats three and four are single crotchets.
Step 2: Beam within the beat
Beam the two quavers on beat two together to show they fill one crotchet beat. Beaming to the beat is what makes the pulse visible to a reader.
Step 3: Check the bar total
Add the values: crotchet plus two quavers (one beat) plus two crotchets equals four crotchet beats, which fills 4/4. If beat two were four semiquavers instead, beam all four under one beam to display the single beat clearly.
Checking your work
Before finishing, sing or play your melody to confirm it is singable and that the climax lands where you intended. Then proofread the notation as a separate pass: does every bar add up, is every stem and beam correct, are accidentals and ties right, and could a stranger play exactly what you hear in your head? Treating composition and proofreading as two jobs catches errors that one read-through hides.
Students often write a note that crosses a strong beat or barline as a single long value, which hides the pulse. Split it into tied notes so the main beats remain visible. A minim starting on beat two of 4/4, for example, is fine, but a value that obscures beat three should be written as two tied notes instead.

Practice8 marksCompose an eight-bar melody in a major key of your choice in 4/4 time. Your melody should use balanced antecedent and consequent phrases, a clear climax, and a perfect cadence at the end. Notate it correctly with clef, key signature, stems and beaming.Show worked answer →
Plan the structure before writing pitches: a four-bar antecedent ending on an open dominant-implying note (the leading note or supertonic), and a four-bar consequent returning to and ending on the tonic for the perfect cadence.
Shape the contour toward a single clear high point, ideally around bar five or six, approached gradually and balanced by stepwise return. Use a small motif and repeat or sequence it so the melody sounds unified.
Notation marks: correct clef and key signature, stems following the rule (up on the right below the middle line, down on the left at or above it), quavers beamed within each crotchet beat to show the pulse, and every bar totalling four crotchets. A musical line with sloppy beaming, or a tidy score with no phrase shape or cadence, each loses marks; the task rewards both a singable melody and a clean, readable score.
Practice5 marksThe following notated bar in 4/4 contains errors in beaming and bar total. Identify two notation errors and explain how each should be corrected.Show worked answer →
Diagnose against the conventions. Error one is usually beaming that crosses or hides a beat, for example four quavers beamed in two groups that straddle the middle of the bar; correct it by beaming quavers within each crotchet beat so beats one to four are visible. Error two is often a bar that does not total the time signature, for example five crotchet beats in 4/4 or a long value that obscures beat three; correct it by adjusting note values or splitting the long note into two tied notes so the bar totals exactly four crotchet beats and the pulse stays clear.
Each correction must state the rule it restores (beam to the beat; bar must total the metre). Naming an error without the correct fix, or "fixing" by changing the time signature when the pitches are fine, does not earn the explanation marks.
