While there has been considerable examination of the under-representation of women in music over the past four decades, little is focused on wind band composition in the Australian context. Similarly, there is limited literature investigating the role that conductors may play in addressing this situation. This inquiry utilises action research methodology and the researcher’s artistic practice to seek strategies that may be employed by conductors to assist in achieving greater gender equality for Australian women composers of wind band music. Using data from interviews with six Australian women composers and a survey of 79 Australian wind band conductors, a greater understanding of the current situation and the potential methods for change are established. Data from the interviews, survey and literature review were analysed via the NVivo software using a hybrid model involving both inductive and deductive thematic analysis. Key findings include the significance of professional networks and educational contexts as well as a need to address repertoire accessibility challenges. A notable outcome of this research is the development of the changemaker conductor model, which outlines how a conductor’s professional practice and sphere of influence can effect change. The inclusion of a portfolio of the researcher’s artistic practice supports this model. Additionally, an examination of the current Australian wind band repertoire was undertaken, revealing a low representation of women composers, and methods for increased generation of new music were investigated, leading to the development of the Australian Women’s Wind Band Composition Award as an exemplar. Finally, the significant potential of educational contexts to create positive change in the field is demonstrated, and implications for educators and institutions are outlined.
