Due to the lack of social systems supporting the cultural productions of migrant societies in Turkey, the venues and opportunities to which migrant musicians have access for the maintenance of their musical practices are limited. Under the given circumstances, especially in the first years after their arrival, street musicianship emerged as a new musical practice for Syrian musicians in Istanbul, and Beyoğlu District, the city’s cultural and political center, has become the venue for street musicians’ performances. Despite undergoing a rapid neoliberal transformation, Beyoğlu district, with Taksim Square and Istiklal Avenue, is a venue of interaction among locals, tourists, and various migrant groups from diverse social classes and identities. As such, it still possesses the potential to be the public sphere which can operate as the space of “a democratic ideal.” For migrant musicians, the street music practices, which fill the very heart of city with their voices and sounds, are means of claiming their existence in the city as potential actors of this public sphere. However, conducting the interaction with the other public space actors and the state officials through street music is not an easy task for Syrian musicians, and it requires the use of tactics from them. In this article, I summarize the given circumstances of Syrian street music performances and discuss the Beyoğlu district in the frame of being—or not being—a public space. I propose street music practice as political action, a “social non-movement”, as Asef Bayat calls it, and situate migrant musicians as political actors who are possible allies of other subaltern groups in Turkey.
