Dance, Singing and Your Brain: What the Latest Science Says

We know exercise is good for the brain. But not all exercise is equal — and the research on music-based movement is now producing some of the most exciting results in the neuroscience of ageing.

Dance outperforms the treadmill

A landmark study published in PLOS One compared the brain effects of various forms of exercise in older adults. Dance-based programs didn't just match the cognitive benefits of repetitive exercise — they significantly exceeded them for brain plasticity, the brain's ability to form new connections and reorganise itself.

One program showed a remarkable finding: participants who danced regularly demonstrated up to 76% lower risk of dementia compared to sedentary controls. That's a number that should stop us in our tracks.

Why does dance work so powerfully? Because it combines so many things the brain loves at once: physical movement, rhythm, memory (remembering steps and sequences), social interaction, emotional expression, and music. It's cognitively rich in a way that walking on a treadmill simply cannot match.

And then there's singing

Group singing has its own extraordinary body of evidence. Regular choral singing has been linked to improved mood, reduced cortisol (the stress hormone), strengthened immune function, and significantly reduced feelings of loneliness and social isolation.

For older Australians — one in five of whom over the age of 75 report persistent loneliness — community singing isn't a nice-to-have. It's a lifeline. And the research backs this up entirely.

"Loneliness has been shown to be as harmful to health as smoking 15 cigarettes a day." — Professor John Cacioppo, University of Chicago

You don't need talent. You need regularity.

The research doesn't discriminate between concert-level performers and those who can barely hold a tune. The benefits appear to come from regular engagement, not musical ability. What matters is showing up, joining in, and allowing music to do what it has always done — bring people together and light up the brain.

PAC Singers — Three Quarter Time's community choir — operates on exactly this principle. No audition. No experience required. Just a willingness to be part of something joyful, regular, and genuinely good for you.

Similarly, our Music as Medicine sessions take the research seriously — offering structured group experiences grounded in the neuroscience of music and designed to support cognitive, emotional and social health.

The bottom line

Movement plus music is one of the most powerful combinations available to anyone over 50 who wants to age well. It's evidence-informed. It's accessible. And it's a lot more fun than most other things doctors recommend.
