Consumer behaviour is one of the areas that requires interdisciplinary research, involving multiple sciences. The influence of music, apart from the everyday life of a person, is an integral tool that serves as a stimulus when shopping, is one of the physical (situational) factors that influence certain consumer behaviours. Apart from the understanding that music is it means to achieve certain goals, we can talk about the manipulation of music, if understood how it can be managed, can achieve a certain result. This brings us to the role of music in retail, which we will explore in this master thesis, where consumers will be questioned about their attitudes and opinions on the influence of music in the store, and answers will be acquired to the questions, which will later be formulated into four hypotheses. The questions to which an answer was sought are as following; does background music in the store affect consumer behaviour, does the choice of background music in the store promote a better mood in customers regardless of gender, are younger consumers, compared to older ones, aware of the background music when they enter the store, get used to the song and no longer pay attention to the song, but to shopping, and do customers leave stores faster if there is no background music due to discomfort. 319 respondents voluntarily participated in an "on-line" survey, and the results obtained through processing and analysis confirmed, or partially confirmed, the previously established four hypotheses. We can thus conclude that music is, more or less, the driver of activity among consumers in the shopping process, and that it has importance (an important factor influencing behaviour) as a part of the interior in marketing planning, as well as a component of a consumer’s life whose aspects are observed through music psychology.
