The Sound You Didn't Know You Remembered

Close your eyes and imagine your school corridor.

Can you hear the bell?

Shoes dragging across the floor. A teacher's voice somewhere in the background. The metal water bottle falling. A classroom fan making that slightly irritating sound.

Funny how quickly the room comes back to life.

You probably haven't heard those sounds together in years. Yet your brain knows exactly where to put them.

That is what fascinates me about sound.

We tend to think memory is visual. We remember old photographs, childhood homes and familiar faces. But sometimes, the strongest memory isn't attached to a picture at all.

It's attached to a sound.

And this has become particularly interesting to me while watching reels.

Sometimes, it's the audio that makes you stop.

Think about hearing the opening notes of a song you haven't heard since college.

Nobody needs to tell you which year it was. Nobody needs to show you a photograph.

Suddenly, you remember the friend you were always with, the café where you spent hours pretending to study, the bus route you took every morning, or simply the version of yourself that existed at twenty-two.

The song didn't store those memories. Your brain did.

The sound simply unlocked them.

Brands discovered this long before Instagram Reels existed.

If I say “Hamara Bajaj”, there's a good chance many Indians won't read those words silently.

They'll hear them.

That gentle, uplifting jingle immediately brings back an entire era of Indian advertising. It wasn't selling just a scooter. It quietly sold aspiration, family, middle-class dreams and the feeling of moving forward together. Years later, people may not remember the exact commercial, but they remember how it sounded.

That's the remarkable thing about sonic memory.

A few notes can outlive an entire campaign.

The same thing happened with the Airtel tune composed by A. R. Rahman.

For years, you heard it before connecting a call, in advertisements, during mobile experiences and across countless touchpoints. Eventually, those few piano notes became bigger than an advertisement. They became an identity.

You didn't need to see the Airtel logo. The sound had already introduced the brand.

That is a very different kind of recall.

We've become obsessed with making everything visually recognisable.

The right logo.The right typography. The right colour palette. The right packaging.

All of it matters. But imagine being recognised with your eyes closed.

A rhythm.

A particular pause.

A voice.

Three familiar notes.

That's when sound stops becoming background music and starts becoming brand memory.

This becomes even more powerful when you combine sound with nostalgia.

A reel about growing up in India doesn't necessarily need grainy footage or a sepia filter. Sometimes all it needs is the click of a cassette shutting, the familiar ring of a landline telephone, the pressure cooker whistle at 7 p.m., or the opening music of a Sunday television programme.

The audience does the rest.

Because nostalgia is about giving someone a cue that allows their own memories to fill in the missing details.

And perhaps that's why sonic branding deserves much more attention than it gets.

A logo asks to be seen.

A sound quietly slips into memory.

So the next time you're creating a reel, don't just ask, “What should people see in the first two seconds?”

Ask something far more interesting.

What should they hear?
