The paper presents three experiments conducted in order to broaden knowledge about the role of music accompanying memory processes. In the first and second investigation the same music and the same list of Polish words were used. The aim of the investigations was to check whether instrumental music - Mozart, Abba composition in instrumental version and culturally distant to subjects music (Chinese folk music) improves or disturbs memory processes when it accompanies memorization (in the first investigation) or precedes recall (in the second one). Both investigations were conducted in individual conditions with university students, respectively 100 and 80 subjects in the first and second investigation. The results showed that the influence of music was very weak, although in line with the hypothesized positive influence of Mozart and Abba, and a negative one of Chinese music. In the last investigation with 136 high school students, the effects of the music preceding or accompanying memorization were the focus of interest. The investigation was conducted in groups with instrumental and vocal, English, versions of the same composition, and subjects were asked to memorize a list of English words. No significant differences were found between the groups. In the general discussion different mechanisms of the potential influence of music on memory processes are put forth: priming, the Mozart effect, proactive and retroactive interference.
