Being an immigrant in a Swedish school today might not be easy. It´s quite difficult to be accepted and becoming a part of an already functioning group. Difficulties with the Swedish language doesn´t make it easier. Besides that the requisites of the school curriculum program are very demanding and Swedish students are often in advantage already being a part of the system for many years. By following five immigrant boys in grade 6 during ten ensemble lessons, one concert and individual interviews with the boys as well as with their teacher, this study aims to investigate how ensemble playing can function as a social tool and promote interaction as well as integration. The results in this study show that ensemble playing in fact can function as a social tool. The boys developed abilities in playing an instrument as well as cooperating and analyzing by using the social tool of ensemble playing. The results even show that ensemble playing can promote interaction as well as integration. Above everything was the concert where the boys acted in front of their classmates and were treated with great respect and acceptance.
