Abstract: The influence of the sounds of music on adults' organisms is well investigated. It is widely known that low rhythm music can diminish psychophysical tension acting as a relaxing and anxiolytic agent, while fast rhythm of the music may have just opposite action-excitement. Despite the big number of publications about the influence of the sounds on human organism only very few papers about fetal reactions on music have been reported. A prospective study of 38 patients with mature pregnancies was made to evaluate the changes in the chosen cardiotocographic (CTG) parameters while listening to the different kinds of the music. Only physiological pregnancies were qualified. In the procedure all the patients were performed a Non Stress Test, than continuing CTG observation were exposed to three kinds of music: low (relaxation), medium (activation), fast rhythm (excitation). Uterine contractility, fetal heart rate (FHR), fetal movements (FM), incidence of accelerations and decelerations, oscillation mid-value were noted. A proportional positive correlation between the uterine contractility, fetal movements and the increase of the rhythm of the music was observed. No influence of the music on fetal heart rate and oscillation mid value was observed. An increased incidence of accelerations while playing the music was reported comparing to the control (i.e. pregnant patients not exposed to the music). No decelerations were observed. CONCLUSIONS: 1. Music has a significant impact on fetal behaviour. 2. Various sounds of music have influence on distinct behaviour of fetus. 3. Increasing rhythm of music intensifies uterine contractility and fetal movements.
