There are currently very few brass bands in schools in Australia, however they were the predominant music ensemble in Australian schools up to the 1970s. The aim of this article is to document the popularity of British-style brass bands in Australia, and the corresponding development of brass bands in schools during the 20th century. The history of the brass band in Australia and its decline is explored, drawing significantly on the historical research of Dr Duncan Bythell, Dr Thomas Fraschillo, Dr Dave Russell, and Dr John Whiteoak. In addition, various primary sources are examined, such as newspaper articles and photographs. British immigration to Australia played a significant role in shaping the brass band movement, which was distinctly male-dominated and had strong links to the military culture of the first half of the 20th century. These societal trends followed into the school brass band setting. The article concludes with an overview of the factors that influenced the shift away from the all-brass ensemble in schools. This research provides a better understanding of the brass band tradition within the context of the school environment in Australia and calls for further research and scholarly inclusion in the literature of music education.
