Drone music is a genre that is an interest of mine. As the musical act, “mystified“, I composed literally thousands of pieces of drone music. The smooth, steady tones of this kind of music emerged with a purpose to bring on a state of calm– to soothe listeners, and perhaps even to induce trance states.
Pushed beyond a certain point, and drone can also resemble the “Flattening Of Affect” symptom– simulating cold, emotionless modes, even ushering them in.
Where to draw the line between a healthy sense of peace and an unhealthy lack of emotion?
