Book excerpt: The Routledge Companion to Jazz and Gender identifies, defines, and interrogates the construct of gender in all forms of jazz, jazz culture, and education, shaping and transforming the conversation in response to changing cultural and societal norms across the globe. Such interrogation requires consideration of gender from multiple viewpoints, from scholars and artists at various points in their careers. This edited collection of 38 essays gathers the diverse perspectives of contributors from four continents, exploring the nuanced (and at times controversial) construct of gender as it relates to jazz music, in the past and present, in four parts: Historical Perspectives Identity and Culture Society and Education Policy and Advocacy Acknowledging the art form’s troubled relationship with gender, contributors seek to define the construct to include all possible definitions—not only female and male—without binary limitations, contextualizing gender and jazz in both place and time. As gender identity becomes an increasingly important consideration in both education and scholarship, The Routledge Companion to Jazz and Gender provides a broad and inclusive resource of research for the academic community, addressing an urgent need to reconcile the construct of gender in jazz in all its forms.
