Modern low brass instruments—trombone, tuba, and euphonium—have legions of ancestors, cousins, and descendants in over five-hundred years of history. Prominent scholar and performer Douglas Yeo provides a unique, accessible reference guide that addresses a broad range of relevant topics and brings these instruments to life with clear explanations and the most up-to-date research.

Brief biographies of many path-changing individuals highlight their influence on instrument development and use. The book's inclusive scope also recognizes the work of diverse, influential artists whose important contributions to trombone and tuba history and development have not previously been acknowledged in other literature. Extensive illustrations by Lennie Peterson provide insight into many of the entries.
