How to cut a song into narrative sections

Before you can plan shots against a song, you need to know where it changes. Three listens, a handful of timestamps and a name for each part — no music theory required.

Every guide on editing to music tells you to "cut on the beat". That is advice for the edit, and it is too small to plan with. A three-minute song has four hundred beats. You can't plan four hundred of anything.

What you can plan with is sections: the five to seven blocks a song is made of. Each one has a different energy, and each one wants a different kind of image. If you know where they start and what each one is for, you know how many shots you need, what kind, and in what order — before you've picked up the camera.

You don't need to read music to find them. You need to listen three times.

What a section is

A section is a stretch of the song where the energy stays roughly the same. It ends when something changes enough that you'd want the picture to change too.

The things that mark a change are easy to hear once you're listening for them:

  • Something enters — the drums come in, the voice starts, a second guitar.
  • Something leaves — everything drops out except a piano; the beat stops for a bar.
  • It opens up — the chorus: louder, wider, more voices.
  • It turns — a bridge that sounds like a different song for a moment.
  • Silence. A gap is a section boundary, always. It is also a gift: silences are cuts.

Three listens

First listen: hands off. Eyes closed if you can. No pausing, no notes. You're only finding out where you react — where you sit up, where you relax. Those moments are the ones your audience will feel too.

Second listen: mark the changes. Play it again with a timer visible and note the second each time something from the list above happens. Don't judge, don't name. You'll get more marks than you need; that's fine.

Third listen: merge and name. Now be strict. Two marks four seconds apart are one change, not two. A change you can hear but wouldn't cut the picture on isn't a section boundary. What survives is your list.

How many is right? Fewer than four and you're only marking "quiet part, loud part" — too coarse to plan shots against. More than eight and you're marking phrases, not sections. For a two- to four-minute song, five to seven is almost always the answer.

A sanity check with numbers

Songs are built in blocks of 4 or 8 bars, so sections tend to have regular lengths. If you know the tempo, you know those lengths:

Seconds per bar = 240 ÷ BPM (for the usual four beats to a bar)

At 120 BPM a bar lasts 2 seconds, so an 8-bar section is 16 seconds and a 16-bar one is 32. At 90 BPM, 8 bars are about 21 seconds.

You don't need this to find the sections — your ears do that. It's useful afterwards: if your sections come out at 16, 16, 31, 17 and 32 seconds, you've found the real structure. If one comes out at 11, you've probably cut in the middle of a phrase; listen to that spot again.

If you can see the waveform, use it too. Section changes usually look like changes: the block gets denser, thinner, or stops.

A waveform cut into six sections of different lengths, each with a name: Silence, Waking up, The run, The bridge, Dawn, Title.
Six sections on a two-minute track. You can see the quiet opening, the denser middle and the drop at the end before hearing a note.

Name them for the film, not for the song

"Verse 1, chorus, verse 2" describes the song. It tells you nothing about what to shoot. Rename each section for what it does in your piece.

It helps to think of each section as having one of a few jobs:

Job What it does What it usually looks like
Hook Earns the next ten seconds One strong, quiet image. Little movement
Context Says where we are and who this is about Wides, establishing shots, faces
Development Things start moving Travel, action, shorter shots
Climax The reason the piece exists Your best footage, fastest cutting
Resolution Lets the audience breathe Longer takes, last light, stillness
Closing Title, credits, sign-off One shot, or black

Not every song uses all six, and some use one twice. The point is that every section gets a job, and no two neighbouring sections get the same one — if they do, they were probably one section.

Then give it a name you'll recognise on location: not "Development" but "The run". Not "Climax" but "Dawn".

When the song doesn't have a chorus

Instrumental tracks, ambient pieces and film scores don't follow verse-and-chorus, and they're the ones people most often use for travel and wedding films. The method is the same; you just follow energy instead of structure. Mark where it rises, where it holds, where it falls. A score that builds for ninety seconds and then releases is three sections — rise, peak, release — even if nothing ever repeats.

What you end up with

A short table. This is the whole deliverable:

A numbered list of sections — Waking up, The run, The bridge, Dawn, Title — each with its number of shots and its start and end time.
Name, start, end. Everything else in the plan hangs off these three columns.

With it you can work out how many shots each part needs — a section's length divided by how long each shot stays on screen — which is the step covered in how to plan a travel film to music. And when you get to the edit, those same start times become markers on your timeline: here's how, for Premiere, DaVinci Resolve and Final Cut.

The same thing in PreFrame

In PreFrame you do this directly on the waveform. Drop the track in, press play, and press C wherever you hear a change — the cut lands on the playhead, on the real second. You can also click the waveform to cut, and click an existing cut to remove it if you were late. Loop a single section to check it starts where you think it does.

Each section gets a name and one of those narrative jobs as a label, and the label gives the section its colour on the timeline.

PreFrame in Focus mode: the waveform with sections and an emotional curve, and below it the 'Silence' section open with its narrative labels — Hook, Context, Development, Climax, Resolution, CTA — and its two shots.
Focus mode: the track, the cuts and nothing else. Each section carries its narrative label and its shots.

And if the music doesn't exist yet — the composer is still writing, or you haven't chosen — you can draw the emotional curve of the piece by hand and cut your sections on that. The day the track arrives, you lay one over the other.

Try it

Do this in PreFrame.

Drop in the track, cut it into sections and place every shot on real seconds — or draw the curve when there's no track yet. Your first project is free and complete.
