The same chords need different melodies in a verse and in a chorus. The difference shows up in range, note count, and where the highest note sits.
Songs are divided into verses, pre-choruses and choruses. Each has a job, so the melody is written differently even over the same chords.
What each section is for
- Verse — where you start talking. Lower range, fewer notes, save the top note.
- Pre-chorus — the run-up. Climb gradually and do not resolve.
- Chorus — the summit. Put the highest note here and repeat heavily.
- Interlude / solo — no vocal constraints, so it can move freely.
- Verse (lower, sparser)
C | G | Am | F
- Pre-chorus (climbing)
C | G | Am | F
- Chorus (higher, busier)
C | G | Am | F
Side by side, the chorus is obviously higher and denser. That difference is the song's shape. Write everything at the same intensity and there is no chorus to arrive at.
A division of a song: verse, pre-chorus, chorus, interlude. Each has a job and needs a different melody.
Save the highest note for one place
The highest note in the song belongs in one spot inside the chorus. Spend it in the verse and there is nowhere left to climb. When a chorus "does not lift", the usual cause is a verse that is already too high.
Generate with the pre-chorus setting. You get a line that climbs towards the chorus.
