Music has been applied for balancing energies that have been disturbed by the stress of modern life. The objective of the present study was to verify the effect of music in labor and on the newborn, when submitted to the same melodies heard by their own mothers during pregnancy. Pregnant women, Health Center users, were submitted to musical sensitization sessions since their fifth month of pregnancy. During labor, the melodies previously selected by the pregnant women were played all the time with a thirty-minute break for every two hours of music. Data collection was performed through interviews performed after labor, at different moments, and the mother' statements were qualitatively analyzed. According to the women's words, music minimized the distress of labor and made it easier for the baby to adjust in the first months of life.
