The moment I'm introduced to a creative agency as "the sonic branding person",the assumption lands before I've said a word: that I'm about to tell them every piece of music their brand uses needs to sound identical. 

Like I'm the sonic police, here to enforce rigid consistency and kill creativity.

No. That's not what this is.

Some of the worst sonic branding I've heard comes from brands who think coherence means sameness. Who commission a sonic logo and then try to force it into every touchpoint whether it makes sense or not.

Retail environments where the same brand theme loops until staff and customers both want to leave. Social content that forces a sonic logo into 6-second clips where it adds nothing.

Coherence isn't sameness. 

Not every brand is Bunnings. Some brands genuinely need maximum recognition through one consistent sound — categories where recall matters and consistency compounds. These are Reinforcer brands.

Many brands aren't Reinforcers. They're Storytellers who need to tell different narratives. Curators who express identity through taste. Hybrids operating across such diverse touchpoints that one sound can't serve all contexts.

A luxury car brand launching a new model needs different music than if they are running a safety campaign. A supermarket brand's seasonal spot should sound different from their sustainability story.

These aren't failures of consistency. They're brands understanding that different contexts require different expressions.

So what does coherence actually mean? It means everything feels like it comes from the same world. The same emotional territory. The same aesthetic universe. Even when the specific expression changes.

Think about a film director with a distinctive style. You can watch three Wes Anderson films with completely different stories, settings, and soundtracks, and they still feel unmistakably like Wes Anderson. That's coherence without sameness.

Coherence comes from shared codes, not identical outputs. Your emotional territory might be optimistic and forward-looking — that doesn't mean every piece needs the same tempo. Your aesthetic world might be organic and acoustic-led — that doesn't mean you can never use electronic elements.

These are boundaries, not boxes. They allow range. What they don't allow is randomness.

Here's where brands get it wrong. They hear "you need flexibility" and interpret it as "anything goes."

I've heard brands with warm, acoustic identities license aggressive electronic tracks because "it felt edgy." That's not strategic flexibility. That's fragmentation.

Real flexibility means understanding what can change and what must stay fixed. The specific song can change. The genre can shift within boundaries. But the emotional territory holds. The aesthetic world holds. The strategic intent holds.

The discipline isn't making everything sound the same. The discipline is ensuring everything operates within the same strategic framework.

That's harder than sameness. But it's what actually builds brand equity.
