Resumen:
The objective of this study was to assess the
effects on heart rate variability (HRV) of exposure to different styles of
"relaxing" music. Autonomic responses to musical stimuli were
correlated with subjective preferences regarding the relaxing properties of
each music style. Linear and nonlinear HRV analysis was conducted in 25 healthy
subjects exposed to silence or to classical, new age or romantic melodies in a
random fashion. At the end of the study, subjects were asked to choose the
melody that they would use to relax. The low-to-high-frequency ratio was
significantly higher when subjects were exposed to "new age" music
when compared with silence (3.4 ± 0.3 vs. 2.6 ± 0.3, respectively, P <
0.02), while no differences were found with "classical" or "romantic"
melodies (2.1 ± 0.4 and 2.2 ± 0.3). These results were related to a reduction
in the high frequency component with "new age" compared to silence
(17.4 ± 1.9 vs. 23.1 ± 1.1, respectively P < 0.004). Significant differences
across melodies were also found for nonlinear HRV indexes. Subjects'
preferences did not correlate with autonomic responses to melodies. The results
suggest that "new age" music induced a shift in HRV from higher to
lower frequencies, independently on the music preference of the listener.
