Hellmann’s has launched one of its strangest marketing stunts yet, attempting to answer a question few in grocery were seriously asking: is mayonnaise an instrument?

In a campaign that leans heavily into internet absurdity, the condiment giant has enlisted academics, music experts and content creators to test whether mayo can, in fact, be used to make music.

What began as a long-running online joke has now been elevated into a full-blown brand campaign, complete with a university-backed study, expert commentary and an original track composed from mayonnaise-generated sounds.

Hellmann’s worked with Dr Rachael Durkin, head of global music technologies at Northumbria University, and her team to explore the issue through organology, acoustics and musicology. Their conclusion: mayonnaise can function as an instrument.

Yes, really.

According to the brand, the research was designed to bring academic rigour to one of the internet’s more ridiculous recurring debates. In practice, it means mayonnaise has been squeezed, dolloped, drummed and plucked in the name of sonic experimentation.

Dr Durkin said: “Music has always evolved through experimentation. When you look at the core principles of how instruments create sound, you realise the possibilities for unconventional materials are endless.

“Exploring something like mayonnaise isn’t just about fun; it challenges our assumptions and invites us to think far more creatively about what music can be.”

To bring the concept to life, Hellmann’s also partnered with creator Andy Arthur Smith, who has more than six million followers across social media, to create a track titled Mayonnaise Is an Instrument, built entirely from sounds made using the condiment.

Smith said: “It’s a question that’s been around for years, but no one’s really tried to answer it properly. Seeing people actually make music with mayonnaise and turning it into a real track has been wild. It shouldn’t work, but somehow it does.”

The campaign is the latest example of brands pushing deeper into chaotic, meme-led marketing in a bid to cut through online. Rather than focusing on taste, provenance or meal occasions, Hellmann’s has chosen to spotlight the physical properties of mayonnaise and turn them into entertainment.

For a brand best known for sandwich spreads and potato salad, it is an undeniably unusual creative direction.

Hellmann’s said the full findings will be published in a report from Northumbria University, giving scholarly backing to a campaign that sounds more like parody than product marketing.

Still, in an era when attention is hard won and brand campaigns increasingly compete on weirdness as much as message, perhaps turning mayo into a musical instrument makes a certain kind of sense.
