It is known that music has a beneficial effect on the neonatal nervous system, behaviour as well as fetal heart rate and reactivity, while some studies show that fetuses change their expression and move their tongue while listening to music from the 16th gestational week. Mozart’s Music is suggested to increase the overall health and mental function in adults but what impact can it have on fetuses? The fetal Doppler PI measurement is well established in the monitoring of fetal wellbeing.
Pulsatility index (PI) is defined as the difference between the peak systolic flow and minimum diastolic flow velocity, divided by the mean velocity recorded throughout the cardiac cycle. It is a non-invasive method of assessing vascular resistance with the use of Doppler ultrasonography. The aim of our study was to identify the impact of Mozart’s music on the resistance in the fetal ductus venosus, umbilical artery and middle cerebral artery.


This is a pilot study. Measurements were done in 60 healthy pregnant women. The pulsating index in the middle cerebral artery, venous duct, fetal umbilical artery and uterine vessels were measured according to the criteria of Fetal Medicine Foundation, with the mother lying calm in a quiet office. Basal values ​​were measured after a 5-minute period of complete relaxation, after which, at rest, participants listened to classical music (Mozart’s Concerto No. 3) at the volume of their choice for 7 minutes. Re-measurement was performed while listening to music. The results were subjected to statistical analysis using the Wilcoxon test. Values ​​of p≤0.05 were considered statistically significant.


The pulsating index was measured in the middle cerebral artery, venous duct and umbilical artery of the fetus, as well as bilaterally in the mother’s uterine vessels. A significant rise in the PI was shown in some of the fetal vessels, demonstarting a marked impact of Mozart’s Music in the fetal cardiovascular system.


It is noticed that Mozart’s music has the ability to affect the fetal heart, however, it cannot be defined whether the effect is negative or positive. Thus, more research needs to be conducted further.
