Music inflames temperament.

Taken at face value, the line suggests that music does not merely reflect a listener’s mood but actively intensifies it—stoking desire, anger, ecstasy, or melancholy into something more volatile. In Morrison’s artistic universe, music is often treated as a catalyst for altered states: it heightens sensation, loosens social restraint, and pushes the psyche toward extremes. “Temperament” here can mean both individual disposition and collective atmosphere, implying that music can charge a room, a crowd, or a performer with heightened emotional energy. The phrasing is blunt and aphoristic, fitting Morrison’s tendency to frame art as a force that provokes transformation rather than passive entertainment.
