This chapter explores the need for music teachers to honor trans and gender-expansive (TGE) students participating in school music programs. Diversity enriches arts engagement, in part, by uniting individuality through communal and collaborative music experiences. School music diversity includes the LGBTQA population and, more specifically, TGE young persons. Music educators benefit from knowing and understanding the lived experiences of TGE young persons as a way to honor and celebrate their individuality. Concepts of gender identity, gender expression, sexuality, and attraction are discussed in an effort to frame a glossary of terms used throughout the book. The authors acknowledge historical contexts in which this text was written. A brief primer of intersectionality is provided to contextualize the complex identities of TGE persons.
