During his lifetime, English composer and poet Ivor Gurney wrote nearly 300 art songs. To date, only 100 of these songs have been published. This book surveys the remaining unpublished manuscripts housed within the Gloucestershire Archives in Gloucester, UK and identifies five as displaying a high degree of craftsmanship as well as potentially brilliant artistic output by Gurney. In an effort to evaluate their viability toward publication, each of the five songs is analyzed, edited, and typeset into performance edition. Included in this book is Gerald Finzi’s original evaluatory catalogue of Ivor Gurney’s collection of art song manuscripts. Audio recordings of these songs are available from the author as are the performance editions with permission from the Ivor Gurney Trust.
