Changes in systemic brain activity under the influence of classic music (minor and major music) were studied based on two groups of healthy children aged five to six years (
n
= 53). In 25 of the children studied, the Luscher test showed the increased level of anxiety, which significantly decreased after music therapy sessions. Bioelectric cortical activity recorded from 20 unipolar leads was subjected to correlation, coherence, and factor analyses. In addition, the dynamics of the power spectrum for each of EEG leads was studied. According to EEG, after listening to both minor and major tones, all children exhibited reorganization of the brain rhythm structure accompanied by a decrease in the level of coherence and correlation of EEG, and a significant and almost ubiquitous decrease in the EEG power spectrum was found. The EEG changes recorded under the influence of classic music seem to reflect a decrease in excess of “internal tension” and weakening degree of “stiffness” in ensuring the activity of the cerebral structures responsible for the mechanisms of “basic integration,” which maintain the constant readiness of the brain to rapid and complete involvement in action.
