It's Music Therapy Week - celebrating and raising awareness of this practice, which crosses artistic and scientific boundaries.
Upbeat caught up with Music Therapist Jez Francis to find out what his job involves.
Jez has spent much of his career with the Manchester Police, but retrained as a RMTh in 2015 in the UK.
He now works in Auckland, and is a Music Therapist at Raukatauri Music Centre.
