Thank you for this interesting article!
What caught my attention was the aspect that "composition was part of a complex system of magical actions."
When I transfer that thought into my daily life and try to remember where moments of my life got meaning, it occurs to me that it were occasions held ritually. A ritual can have magic power. The second ingredient is consent. The more people believe in that magical action the more real it becomes.
hmmm.. I will think more about this matter.
