Music festivals are meant to create a unique experience for those who attend them, and this occurs through multiple phenomena. Among these phenomena are various cultural identification processes, which may be directly connected to festivalgoers’ emotions. In this scope, the main aim of this research is to understand how music festivals trigger, shape, reinforce and influence cultural identification processes and how these processes relate to the emotions felt by festivalgoers. In order to attain this aim, we present the academic state of the art in terms of models for evaluating intangible impacts and emotions in different settings. We then propose a model and a mixed-method approach for analysing such impacts on music festival experiences. This model is based on attendees’ perception of cultural impacts and music emotions during these experiences. Finally, we apply these different methodological approaches to the study of a classical music festival experience. We then draw conclusions about the relationship between festivalgoers’ emotions and identification processes. Specifically, there is a clear relationship between intense positive emotions and regional identification processes, cultural skills development and growth in music listening, where the festival experience encourages attendees to add new music to their musical preferences.
