Arranging a Song with Sections and Markers

Once a project has more than a handful of tracks, working section-by-section gets hard to manage without some structure. GarageBand's arrangement markers solve exactly this.

Adding the Arrangement track

Open the Arrangement track (usually available from the track area's view options, or added like any other track type). This creates a dedicated lane above your regular tracks specifically for labeling song sections.

Creating and naming sections

Click to add a new arrangement marker at a point on the timeline, then rename it to something meaningful — Intro, Verse 1, Chorus, Bridge, Outro. Drag a marker's edges to resize exactly how many bars that section spans.

Why this is worth the setup time

Once sections are marked, you can:

• Click a section header to select every track's content within that section at once, instead of manually selecting across a dozen tracks.
• Drag a whole section to reorder it — moving a chorus earlier, or swapping verse and bridge order, updates every track together automatically.
• Duplicate a section, instantly copying every track's content within it — the fastest way to repeat a chorus without re-recording or manually copying each track.

A practical arranging workflow

1. Build one full pass of your song loosely — even a rough sketch.
2. Add arrangement markers over what you've built, labeling each section.
3. Step back and evaluate structure at a glance: is the intro too long? Does the second verse need trimming? Would the song benefit from an extra chorus?
4. Use section duplication and reordering to test structural changes quickly, without redoing the underlying performances.

Arranging is a compositional tool, not just an editing shortcut

Because reordering sections is so fast this way, it's worth actually experimenting — try the chorus first, try cutting a verse, try a shorter intro. Testing these ideas costs almost nothing once your sections are marked, and structure has an outsized effect on how a finished song feels.
