Here's why being a musician is good for your brain

Turns out, a musician's brain has an edge on the ageing process.

A recent study conducted at Baycrest Health Sciences uncovered a crucial piece into why playing a musical instrument can help older adults retain their listening skills and ward off age-related cognitive declines.

This finding could lead to the development of brain rehabilitation interventions through musical training.

The study found that learning to play a sound on a musical instrument alters the brain waves in a way that improves a person's listening and hearing skills over a short time frame. This change in brain activity demonstrates the brain's ability to rewire itself and compensate for injuries or diseases that may hamper a person's capacity to perform tasks.

Senior author Bernhard Ross noted that music has been known to have beneficial effects on the brain, but there has been limited understanding into what about music makes a difference.

"This is the first study demonstrating that learning the fine movement needed to reproduce a sound on an instrument changes the brain's perception of sound in a way that is not seen when listening to music," Ross added.

The study involved 32 young, healthy adults who had normal hearing and no history of neurological or psychiatric disorders. The brain waves of participants were first recorded while they listened to bell-like sounds from a Tibetan singing bowl (a small bell struck with a wooden mallet to create sounds). After listening to the recording, half of the participants were provided the Tibetan singing bowl and asked to recreate the same sounds and rhythm by striking it and the other half recreated the sound by pressing a key on a computer keypad.

The study's next steps involve analyzing recovery between stroke patients with musical training compared to physiotherapy and the impact of musical training on the brains of older adults.

The study is published in the Journal of Neuroscience.
