I heard an interesting show about music therapy on the radio a couple of days ago. Both my parents are professional musicians so I was keen to think about it.
I was thinking about how it worked—how music can have such an impact on the brain. I've been writing about causality and my view is that something can change, destroy or deeply impact something else when it becomes formally very regular. An earthquake is a more regular than normal oscillation of tectonic plates. A stroke is a weirdly regular brain wave pattern.
I was wondering whether the stacking of music, suggestion, lyrics and memory on top of one another in music therapy was what had such an impact. That it's the synchronization of many objects that has this effect, holding the mind and allowing new connections to be established.
