Piper and academic Simon McKerrell has published a book on Scottish Traditional Music aimed at a wide audience.
Focus: Scottish Traditional Music engages methods from ethnomusicology, popular music studies, cultural studies, and media studies to explain how complex Scottish identities and culture are constructed in the traditional music and culture of Scotland. This book examines Scottish music through their social and performative contexts, outlining vocal traditions such as lullabies, mining songs, Scottish ballads, herding songs, and protest songs as well as instrumental traditions such as fiddle music, country dances, and informal evening pub sessions. Case studies explore the key ideas in understanding Scotland musically by exploring ethnicity, Britishness, belonging, politics, transmission and performance, positioning the cultural identity of Scotland within the United Kingdom.
