The intensifying human flow globally increases the significance of research on cross-cultural adaptation. The challenges caused by cultural differences have been researched thoroughly in the literature. However, rather than focusing on the challenges, this research investigates the effect of the common practice which crosses borders of any culture; collective musicking as a social activity in an intercultural context. Thereby, the main inquiry is how collective musicking shapes migrants’ cross-cultural adaptation who arrived in Poland from various countries. For this purpose, the current research investigates the relevance between migrants’ sociocultural adaptation and musicking as a social activity. While the theoretical framework of sociocultural adaptation resides in the behavioural realm and can be defined as migrants’ ability to fit in or execute effective interactions in the host society, the concept of collective musicking refers to any activity involving or related to music performance collectively. Thus, linking these two concepts in research is beneficial to depict how collective musicking shapes the reality of migrants and how migrants position themselves in their new cultural settings. Even though the research study has different sections dealing with various aspects of musicking migrants, this paper emphasises identity formation and expression through musicking among migrants with different cultural backgrounds. Accordingly, the study focuses on the expression and formation of both, collective and individual identity processes. As the nature of the study has a qualitative approach, in-depth interviews and observations are the primary tools for data collection. In addition, auto-ethnographical entries are planned to be employed to enrich the data collected from musicking migrants who reside in Poland. Lastly, unexpected findings from the pilot study are worth focusing on, as it is an under-explored phenomenon in the literature. Accordingly, privileges shown to the musicking migrants by the locals in various contexts is a phenomenon that may be enabling international migrants to adapt faster and easier to the environment they are in.
