Drone's apparent monotony resolves into micro-tonal detail only under sustained, attentive listening

The common charge that drone is monotonous mistakes stillness for emptiness. A complex drone is full of micro-tonal events, tiny structures, and slow shifts that become audible only to a listener who sustains attention long enough to immerse in it; what sounds like the same thing repeating opens into layers, elevations, and depth. Drone therefore demands a different listening posture — not tracking melodic development but attuning to the present moment and to small variations, which is why the article says drone ‘changes little of the original piece of music, but so much more in terms of the audience’s actual act of listening.’ Distorted drones extend this by dissolving tones into entropic noise that can carry the whole emotional range from calm to fear.

Examples

John Cage: ‘if you do something and it’s boring… do it again until it becomes interesting.’ ‘Organ²/ASLSP’ (begun 2001, ends 2640) as the extreme. Micro-tonal beating and overtone shifts emerging over a long sustain.

Assessment

Explain ‘deep listening’ for drone: what the listener must do differently from melodic listening, and one micro-tonal phenomenon that emerges only with sustained attention.
