This book, the first of its kind, is a study of Bolognese instrumental music during the height of the city''s musical activity in the late seventeenth century. The period”marked by a rapid expansion of the cappella musicale of the principal city church, San Petronio, by the founding of the Accademia Filarmonica, and by increasingly lavish patronage of musical events”witnessed the proliferation of repertory for instrumental ensembles. This music not only reveals crucial stages in the development of the sonata and concerto but also recalls the elaborate church rituals and the opulent public and private celebrations in which they figured prominently. Moreover, the late seventeenth century saw the heyday of Bolognese music publishing, whose output of sonatas and related instrumental genres easily surpassed that of the once-dominating Venetian presses. The approach taken here departs from composer- and genre-centered monographs on Italian instrumental music in order to illuminate an array of topics that center on the Bolognese repertory: the social condition of instrumentalist-composers; the acumen of music publishers in the creation of the repertory; the diverse contexts of the instrumental dances; the influence of liturgical traditions on sonata topoi; the impact of psalmodic practice on tonal style; and the innovative climate that led to experiments with scoring and form in the earliest instrumental concertos. In sum, this book not only illustrates the historically significant and defining features of the music, but also links the surviving repertory to the flourishing musical culture in which it was created.
