A method and device for presenting music to a patient in real time synchrony with relation to every single pulse of the patient's heartbeat, thereby inducing an enjoyable and relaxing sensation. A digitized electric signal representative of the patient's heartbeat is fed to a microprocessor which brings the digitized electric signal into correspondence with a sequence of musical sound configurations so that each pulse beat is followed by one of the sound configurations in real time. The sequence of musical sound configurations is presented to the patient so that each sound configuration is played in real-time synchrony with a respective pulse beat.
