Monteverdi’s Vespers is an exceptional collection of sacred music, both in the inventiveness of the compositions that it contains and in the debate that it has provoked over its use in the seventeenth century and over Monteverdi’s intentions in publishing it. This Handbook provides a guide to the music in all its aspects – from an introduction to the service of Vespers itself, through the practice of chanting psalms in plainsong to analysis of Monteverdi’s settings.
