Melody is what most people remember about a song. You do not need to understand theory to write a great one - but knowing how melodies work gives you more ways to fix one that is not quite there.
Contour
The shape of a melody - how it rises and falls - is its contour.
- Arch - rises to a peak and falls. The most common shape; it feels complete.
- Rising - builds tension and energy. Often used into a chorus.
- Falling - resolves, relaxes. Often ends phrases.
- Wave - rises and falls repeatedly.
The highest note of a section is its emotional peak. Save the highest note of the whole song for the chorus, and use it sparingly.
Range
- Most singable melodies stay within an octave to an octave and a half.
- Verses usually sit lower, in a conversational range. Choruses rise, where the voice has more power.
- Writing for a particular singer? Find their comfortable range first. A melody that sits at the very top of a voice for a whole chorus sounds strained.
Steps and leaps
- Steps - moving to an adjacent scale note. Smooth, singable, natural.
- Leaps - jumping a third or more. Dramatic, emotional, attention-grabbing.
Most strong melodies are mostly steps with occasional leaps. A useful rule of thumb: after a big leap, move back by step in the opposite direction. It balances the line.
Motifs, repetition and variation
A motif is a short melodic idea - three to five notes - that is repeated and developed.
- Repeat it exactly to make it memorable.
- Transpose it - the same shape starting on a different note.
- Vary the ending - repeat the first half, change the second.
- Rhythmic variation - same notes, different rhythm.
The classic pattern: an idea, a repeat, a variation, and a resolution. A - A - A' - B. Listen for it in almost any chorus.
Rhythm in melody
Rhythm is often what makes a melody distinctive. Two melodies with the same notes in different rhythms are different melodies.
- Syncopation - starting phrases before or after the beat - makes melodies feel modern and conversational.
- Rests - give the melody room to breathe and the listener time to absorb it.
- Rhythmic contrast between sections - a busy verse, a long-note chorus, or vice versa - makes each section feel distinct.
Melody and harmony
- Strong beats get chord tones. A melody note on beat one that belongs to the chord sounds stable.
- Weak beats can use passing notes from the scale.
- Tension notes - a note that clashes with the chord, held on a strong beat, then resolving by step - create the most emotional moments. This is called an appoggiatura, and it is the moment in a ballad that gives people goosebumps.
Call and response
A phrase followed by an answer: a vocal line and an instrumental reply, or two vocal phrases that mirror each other. Rooted in African-American musical traditions - blues, gospel, work songs - it runs through soul, funk and hip-hop. It gives a melody conversation and space.
Do this now
- Write a four-bar melody over your C major project using an A-A-A'-B structure.
- Make sure every strong beat lands on a chord tone; then deliberately move one onto a non-chord tone that resolves by step.
- Raise the chorus melody so its highest note is higher than anything in the verse.
- Write an instrumental answer to the end of each vocal line.
