The variability of the heart rate reflects the regulatory status of the autonomous nervous system. For analytic purposes accessible to laypersons, the authors developed methods to transform heart rate variability into acoustical information, through either direct sound synthesis or the production of MIDI files (musical instrument digital interface) to trigger other devices. The authors describe the methods and some results and discuss applications for analytical and artistic purposes, such as music composition and biofeedback. The resulting “music” is complex and rhythmic and often has unexpected and interesting implied harmony.
