Music festivals are based on an intangible experience, and a timed moment in which the overall atmosphere is managed. Taking into account the fact that Croatia, as a primarily touristic country, generates income from music festivals that are closely related to tourism, the aim of this paper is to investigate the visitors perception about the service quality factors at music festivals in the Republic of Croatia in order to detect the importance of individual factors when organizing a music festival and direct the service quality management process. During the preparation of the thesis, secondary data collected from scientific and professional literature were used as a basis for conducting primary research and were processed using methods of analysis, comparison and synthesis. The primary descriptive research was conducted on a convenient sample of visitors to music festivals in the Republic of Croatia (the number of respondents is 150), and the data was collected using a highly structured survey questionnaire. The questionnaire is based on the FESTPERF scale, specialized for measuring service quality at music festivals. The results obtained by measuring the perception of factors of service quality showed which factors and to what extent increase visitor satisfaction. Respondents showed a high level of satisfaction in matters related to the professionalism of the service at music festivals in Croatia. Core services and the environment show a slightly lower level of visitor satisfaction in relation to the professionalism factor. We can conclude that the importance of the service quality of music festivals is crucial in order for Croatia to continue to realize significant benefits from this activity and for tourists to continue visiting festivals and explore the beauty of Croatia in general.
