A note, sustained. A nervous system, listening.
Body & Sound
The body responds to sustained tone.
We are not therapists, and a handpan is not medicine. But the research on prolonged exposure to tuned acoustic vibration has, in the last fifteen years, moved from the fringes of wellness literature into peer-reviewed journals. A summary of what has been measured.
A single 12-minute session lowered tension, anger and fatigue across a community sample of adults.
Across sixteen studies, listening to slow, sustained, low-frequency music lowered cortisol relative to silence.
Slow, low-tempo classical and meditative music improved heart-rate variability, a marker of nervous-system flexibility.
Forty-five minutes of relaxing instrumental music before bed reduced the time it took participants to fall asleep.
Slow, predictable acoustic stimuli measurably shifted the alpha-band activity associated with relaxed attention.
Across ninety-seven trials and nine thousand patients, music, sustained and low-arousal, reduced reported pain in clinical settings.
Reading the research yourself.
We don't want you to take our word for any of this. The studies cited above, plus a handful of overviews, are listed below — most are open-access or freely available abstracts.
