A prolific music theorist and critic as well as an established composer, Johannes Mattheson remains surprisingly understudied. In this important study, Margaret Seares places Mattheson‘s Pi‘s de clavecin (1714) in the context of his work as a public intellectual who encouraged German musicians and their musical public to eschew what he saw as the hidebound traditions of the past, and instead embrace a universalism of style and expression derived from contemporary currents in music of the leading European nations. Beginning with the early non-musical writings by Mattheson, Seares places them in the context of the cosmopolitan city-state of Hamburg, before moving to a detailed study of his first major musical treatise Das neu-er ffnete Orchestre of 1713, in which he espoused his views about the musics of the past and present and, in particular, the characteristics of the musics of Germany, Italy, France and England. This latter section of the treatise, Part III, is edited and translated into English in the book''s appendix - the first such translation available. Seares then moves on to an evaluation of the Pi‘s de clavecin as a work in which Mattheson reflects in musical terms the themes of modernism (in the sense ofa mode) and universalism that are such a strong part of his writings of the period, and a work that represents an important precursor for the keyboard suites of Johann Sebastian Bach and Georg Frideric Handel.
