How does music therapy benefit those with autism?
Music therapy is a creative, relationship-based approach that uses musical interaction to support communication, emotional expression, and engagement. Autistic children, young people, and adults often respond strongly to rhythm, predictable structure and non-verbal communication, which can make musical environments feel more accessible than traditional talk-based therapies. According to the National Autistic Society, music can encourage emotional release, reduce stress and help build social connections in a supportive setting.
NICE does not currently recommend music therapy as a core autism intervention. Surveillance reports note that it was not included in guideline development due to limited evidence at the time. Current guidance for children (NICE CG170) and adults (NICE CG142) focuses instead on psychosocial, communication-based and functional skills interventions. NHS autism support pages (NHS.uk) Likewise, do not list music therapy as a routinely commissioned service, though some local areas offer it.
What research shows
Evidence for music therapy is mixed but promising in several key areas. A Cochrane Rehabilitation review summarised for clinicians reports that across 26 studies, music therapy “probably produces an overall improvement” in quality of life and symptom severity for autistic people, with uncertain effects on specific social-communication outcomes. A commentary for UK practitioners also suggests possible improvements in global functioning and wellbeing, while calling for more rigorous trials as mentioned in BJPsych Advances.
Large trials have shown varied results. An NIHR Evidence-summarised multicentre RCT found that specialist-led improvisational music therapy did not improve primary measures of social and communication skills compared with enhanced standard care, though some secondary outcomes showed small gains. By contrast, a 2022 meta-analysis reported modest improvements in social interaction across eight RCTs mentioned in Frontiers in Psychiatry.
Emerging research is exploring adapted models. A UK-linked feasibility RCT trial found that a music-assisted communication programme increased social responsiveness more over time than a standard communication intervention, suggesting potential as part of communication-focused support rather than a stand-alone therapy.
How it may help in practice
Music therapy appears to be most beneficial when used to support participation, communication, and emotional regulation. NAS service directory examples show how musical interaction can encourage engagement and shared attention. Mechanistic studies suggest that rhythm, auditory-motor synchrony, and structured turn-taking may enhance attention to verbal and social cues.
Takeaway
Music therapy can offer meaningful benefits for some autistic people, particularly in emotional expression, engagement and short-term wellbeing but evidence remains mixed, and it is not recommended as a core intervention by NICE and NHS. When used, it is best delivered as part of a wider, person-centred support plan rather than as a treatment for autism itself.
