Often called the musical equivalent of the Dead Sea Scrolls, the Trent codices have dramatically broadened our understanding of Renaissance music. Much has been written about this collection of fifteenth-century music manuscripts, most of which were discovered in the Cathedral at Trent, but none of the seven codices—generally called Trent 87 through Trent 93—has ever been published in its entirety. Thus Rebecca Gerber’s edition of Trent 88, which took more than a decade to prepare, will be the first to appear. As such, this volume is a landmark in the publication of early music. Trent 88 comprises an extensive anthology of 145 compositions tailored to the ceremonial and daily religious services of the period. The international scope of the collection is both impressive and significant: early English, French, German, and Spanish mass cycles appear alongside simple hymns and Magnificats. Music by renowned composers—including Guillaume Du Fay, Johannes Ockeghem, Johannes Cornago, and John Bedingham—is joined here by an even larger repertory of anonymous compositions with great aesthetic and historical value. Edited to accommodate both scholars and performers, and augmented with Gerber’s expert introduction, this volume will significantly deepen existing knowledge of a crucial period in the history of music.
