I found this session as gratifying as my classes at film school. The lecturer explained how through good theology and a little creativity, Jazz music can really help in faith integration issues. For example, by its very history, Jazz can serve to help reconcile racial relations. Jazz is immediately accessible. Jazz can help correct that tendency of privatization in worship.
Jazz is individual yet communal and it calls one to participate.
After this lecture, we had a really hot Jazz concert by talented Jazz musicians who were believers. Art is for more than personal or communal enjoyment. If integrated properly with other elements like truth and emotion, the impact can be impressive. For example, if a church emphasizes emotions over beauty and truth, one gets a Charismatic church. If a church emphasizes beauty over truth and emotions, one gets what the Catholics and Anglicans have.
