Today we usually think of a book of poems as composed by a poet, rather than assembled or adapted by a network of poets and readers. But the earliest European vernacular poetries challenge these assumptions. Medieval songbooks remind us how lyric poetry was once communally produced and receiveda collaboration of artists, performers, live audiences, and readers stretching across languages and societies. The only comparative study of its kind, Songbook treats what poetry was before the emergence of the modern category poetry: that is, how vernacular songbooks of the thirteenth to fifteenth centuries shaped our modern understanding of poetry by establishing expectations of what is a poem, what is a poet, and what is lyric poetry itself. Marisa Galvez analyzes theseminal songbooks representing the vernacular traditions of Occitan, Middle High German, and Castilian, and tracks the process by which the songbook emerged from the original performance contexts of oral publication, into a medium for preservation, and, finally, into an established literary object. Galvez reveals that songbooksin ways that resonate with our modern practice of curated archives and playlistscontain lyric, music, images, and other nonlyric texts selected and ordered to reflect the local values and preferences of their readers. At a time when medievalists are reassessing the historical foundations of their field and especially the national literary canons established in the nineteenth century, a new examination of the songbooks role in several vernacular traditions is more relevant than ever.
