Choir singing and the brain

By Tone Tellefsen-Hughes

There is something extraordinary happening inside the brain when we sing together.

Anyone who has stood in the middle of a choir already knows it feels good. But researchers are now discovering that choir singing may also be one of the most powerful activities we can do for long-term brain health.

When we sing in a choir, the brain lights up in remarkable ways. Unlike many activities that rely on just one area of the brain, singing recruits multiple regions all at once, including those responsible for memory, language, emotion, movement, breathing, listening, coordination and social connection.

Learning lyrics exercises memory systems, particularly the hippocampus, the area of the brain associated with learning and memory formation. Following rhythm and cadence activates timing and attention networks, while matching pitch and singing in harmony requires the brain to constantly listen, adjust and respond in real time.

In many ways, choir singing is a full-brain workout.

Researchers at the University of Helsinki found that regular choir singing is associated with better cognitive performance, improved verbal fluency, stronger working memory and greater emotional wellbeing across adulthood. Some studies even suggest choir singing may help support healthy ageing and cognitive resilience later in life.

Scientists are also discovering physical changes in the brain linked to singing. Brain imaging studies have shown enhanced connectivity in white matter pathways, the communication networks that help different parts of the brain work together efficiently.

And then there is the breathing.

Singing naturally encourages slower, deeper, more regulated breathing patterns. This increases oxygen flow throughout the body and supports circulation to the brain. Deep breathing is also linked to calming the nervous system and reducing stress hormones. Some emerging research even suggests breathing rhythms may help coordinate memory processes connected to the hippocampus.

But perhaps one of the most beautiful discoveries is what happens when people sing together.

Studies have found that choir members can begin to synchronise not only musically, but physically too, with breathing patterns and even heart rhythms becoming aligned. There is something profoundly human about harmony. The brain constantly balances hearing your own voice while blending with those around you. It is cooperation, listening and connection happening moment by moment.

Maybe this helps explain why choir singing can feel both energising and calming at the same time.

At ChoirBLAST, we witness this every year. Hundreds of voices, different stories, different backgrounds, all coming together for one extraordinary weekend of song. And perhaps, alongside the joy, laughter and goosebumps, we are also giving our brains something deeply nourishing.

Choir singing is not just good for the soul.

It may also be one of the healthiest things we can do for the brain.

And that feels worth singing about.

Join us at our next event and give your heart, soul and brain a joyful workout.
