Why the tune usually comes before the words
Launch library · evergreen read
In much of film music composition, the melody is typically written first, with lyrics fitted carefully onto that existing musical shape afterward, rather than the more familiar songwriting approach of setting words to music. This ordering shapes the entire collaborative relationship between composer and lyricist throughout the songwriting process.
Composers usually work out a tune's basic contour, its rise and fall, its rhythm and phrasing, often using placeholder syllables or a rough vocal hum, before handing the finished melodic shape to a lyricist. That lyricist then has to find words whose natural rhythm and emphasis land precisely on the correct musical beats and stresses.
This constraint demands a particular kind of writing skill, since a lyricist working this way cannot simply write freely and hope the words fit later. Every syllable has to serve both meaning and melody simultaneously, a discipline quite different from writing poetry or prose without any pre-existing musical structure to answer to.
The results, when this collaboration works well, feel entirely natural to a listener, as though the words could only ever have been set to that particular tune, even though the melody, in truth, was very often composed first and the words fitted carefully around it.
