In this chapter I will discuss how other musicians can affect the possibility of flow and the creation of meaningful performances. Almost without exception, earlier research on flow does not mention collectivity. This study addresses this lack and highlights the importance of collectivity in the creation of flow. Analysis shows that collectivity can assume different forms and affect many aspects of musicians’ work, the most important being the establishment of shared feelings among a band. These feelings and the other musicians are significant for the individual’s experience of flow. This chapter discusses the importance of trust and support within the band, shared goals, other musicians’ attitudes and communication within the band.
