There’s a conversation that comes up regularly in music schools like ours. A parent sits across from me, a little hesitant, wondering whether their child really needs music lessons — or whether sport, tutoring, or another activity might be a better use of limited time and money.
It’s a fair question. And the honest answer, backed by a growing body of research, is that few structured activities offer a developmental return on investment quite like music education.
This isn’t an argument for pushing every child toward a concert stage. It’s about what music actually does to the developing brain — and why what happens in a piano lesson, a group class, or a music playgroup matters well beyond the music itself.
When a child learns music, the brain doesn’t just get better at music. It gets structurally better at a range of tasks — and this is the finding that keeps showing up across research groups, universities, and countries.
A comprehensive review published in Frontiers in Psychology synthesised the existing evidence on music training and **executive function** in preschool children aged 3–6. Executive functions are the cognitive tools we use to:
The meta-analysis found consistent, positive effects from music training on these skills, particularly in working memory and inhibitory control (the ability to pause before acting on an impulse).
This matters in practical terms. A child who can hold instructions in mind and wait their turn is easier to teach across every subject. Music education appears to be one of the more effective early interventions for building that capacity.
Put simply: learning to play an instrument is one of the most cognitively complex tasks a young child can take on. That complexity is precisely what makes it valuable.
One area where the research is becoming increasingly compelling is the relationship between music education and literacy.
A study examining cortical tracking of speech — the brain’s ability to synchronise with the rhythm of spoken language — found that musical training was linked to enhanced reading ability and phonological awareness in children aged 5–9.
The mechanism is fascinating: the brain processes speech by locking onto its rhythms to break down a continuous stream of sound into recognisable words. The researchers found that musically trained children showed a brain pattern closer to that of advanced readers, suggesting that music accelerates the brain’s journey toward reading maturity.
The Power of Early Song: A systematic review on language delays reinforced that songs meaningfully improve a child’s word learning and speech fluency. One cited study found that when parents sang with their babies regularly by 6 months of age, those children had measurably larger vocabularies by 14 months.
It’s worth being honest about the limits here, because development genuinely is complex.
Music lessons won’t turn every child into a prodigy overnight, and a single term of group classes isn’t a guaranteed academic booster shot. Some short-term studies show weaker results because the benefits of music education compound over time. Consistency matters far more than short bursts of intensity.
If you would like to see how we blend science-backed developmental tools with genuine fun, come along to a session. We run tailored group music programs across early childhood and primary school ages, built precisely around how their brains grow.
