Twin-peak effect in both cardiac response and tempo of popular music.

How the musical tempo affects the performance of heart rate variability (HRV) was studied in this work. By understanding the relationship between the HRV response and the music tempo with decreasing tempo from 140 to 70 beats per minute (bpm) periodically in six successive weeks. There were two groups in the experiment, one was listening drum loop music 3 minutes in the middle of experiment and the other was just rest for 20 minutes.

HRV response of vegetative state patient with music therapy.

This case study centered on the effects of Music Therapy (MT) on vegetative state (VS) patients for a continuous 41-day experiment with electrocardiogram (ECG) recorded. Mahler's Second Symphony was used for this MT. There are various elements in Mahler's second symphony, with string, wind, drum, and even voice; providing the subject a strong and dynamic stimulation.
