  • 20 healthy preterm infants (post-menstrual age of 30 to 37 weeks).


  • Infants were randomly assigned to be exposed to a 30-minute period of Mozart music or no music on 2 consecutive days.


  • Resting energy expenditure was similar during the first 10-minute period of both randomisation groups.
  • During the next 10-minute period, infants who were exposed to music had a significantly lower resting energy expenditure than when not exposed to music. This was also true during the third 10- minute period.
  • Thus, on average, the effect size of music on resting energy expenditure is a reduction of approximately 10% to 13% from baseline, an effect obtained within 10 to 30 minutes.


  • Yes (with confidence)


Editors Notes

  • Music has been shown to reduce stress, decrease heart rate and salivary cortisol, and increase oxygen saturation, nonnutritive sucking rate, and even weight gain in preterm infants.
  • Note that the study was small in both the number of participants and duration.
