Though any slow music can promote sleep (provided it has around 60 to 80 beats per minute) classical music goes further and even impacts the ‘parasympathetic nervous system’ of the body, which is responsible for resting and digesting food.

Frédéric Chopin’s Nocturnes, 21 solo piano pieces that transform the mind into a dream state, are masterpiece compositions that even mimic the oncoming of sleep by ending without any ending, similar to how one never registers the exact moment one falls asleep.

Whether it is an eight-hour soundscape on Headspace, or a Sleep Whispers podcast that tell stories in a whispering mode to calm and hypnotize the brain, the sonorous format used is called Autonomous Sensory Meridian Response(ASMR) that uses sonic triggers to induce euphoria and relaxation in the brain, pushing it towards a dream state.
