An interlude is the section placed between vocal sections, carried mainly by the instruments. By letting the melody rest and putting instrumental phrases, rhythm, and timbre in the spotlight, it gives the song breath and change.
The role of an interlude
In a song where the singing keeps going, the interlude is where the ear resets. Changing the air before the next lyric, showcasing a memorable phrase, making room for dancing or visuals – the purposes vary.
What to showcase
Choose an element at the core of the song: a guitar or synth solo, a striking short phrase, a change in the drums, or just the chord progression. Rather than only adding new elements, playing part of the vocal melody on an instrument is another approach that holds together well.
Deciding the length
Matching the bar feel of the song, with four or eight bars for example, makes it sit naturally. Short, it is a transition; long, it becomes another highlight of the song. How much build you need also depends on whether you return to the same section afterward or head into the final chorus.
How it differs from a bridge
Interlude is often used as a word for the performing format, while bridge is used for a structural function within the song. In practice they can overlap, so look not only at whether there are vocals but also at how the section changes the flow of the song.
Tips for building one in a DAW
Start by muting the vocal parts and looking for a place where the accompaniment carries through on its own. Adding a fill, a change of sound, or automation there makes it sound like development rather than mere empty space.
