Abstract Music is a medium for people to convey information and express their feelings, and meanwhile it has a great influence on the cognitive activities. In this paper, the improved Sternberg working memory task experiment was designed, and 20 subjects were selected to participate in the experiment. The EEG data of subjects in remembering English words under the background of classical music and rock music were collected and the cross-correlation method was used to calculate Pearson between channels. The brain function networks were built and the network properties were analyzed to explore the impact on working memory of two kinds of music stimulations. Results showed that the connections between the frontal lobe and the occipital lobe in the state of classical music and rock music were significantly increased compared to that in the state without music, and the connection in the state of rock music was significantly greater than that in the state of classical music. Compared to the brain functional network in the state without music, rock music and classical music stimulations increased the node degree, betweenness center degree, clustering coefficient and closeness, shortened the average path length, enhanced the small world property and improved the global efficiency. It was shown that the music stimulations improved the activity of the brain. It was proved that different music stimulations have significant impacts on the learning task. The results of behavioral data showed that the correct response rates of the subjects under no music stimulation, classical music state and rock music state were about 91%, 86% and 80%, respectively, and the average response times under three states were 728 ms, 761 ms and 818 ms, respectively. It could be seen that the music stimulations reduced the correct response rates of the subjects and increased the response times, which indicated that the musical stimulations interfere with the working memory.
