INSTRUMENTS AND PERFORMANCE The Art of Partimento: History, Theory, Practice. By Giorgio Sanguinetti. New York: Oxford University Press, 2012. [xiii, 385 p. ISBN 9780195394207. $49.95]. Music examples, bibliography, index, companion Web site.The subject of partimento practices, which came to prominence in the Neapolitan compositional school during the late seventeenth and early eighteenth centuries, has received considerable scholarly attention in the twenty-first century. Beginning in 2004 with Florian Grampp's four-part series of articles under the general title Partimenti-Musik fur Generalbass solo in Concerto: Das Magazin fur Alte Musik (I: Johann Matthesons Grose Generalbass-Schule, 21, no. 193: 23-29; II: Romische Quellen zur Partimento-Praxis, 21, no. 194: 23-27; III: Zur neapolitanischen Partimento-Tradition, 21, no. 196: 26-27; IV: Solistischer Generalbass in Nord-und Mitteldeutschland, 22, no. 199: 32-35), variety of topics pertaining to these practices and their influence on composers and pedagogues in Italy-and, indeed, throughout Europe-have been the subject of earnest investigation. Sanguinetti's effort in this area offers new and valuable insights into the historical background of this tradition; further, the book explores the theoretical implications of these practices, and guides the interested reader in the complex art of realizing partimento line as well.The book is divided into four large sections, with part 1 offering history of the tradition. In chapter 2, Sanguinetti presents basic definition: A partimento is sketch, written on single staff, whose main purpose is to be guide for improvisation of composition at the (p. 14). Partimenti were originally conceived as an alternative form of notation; early references to this term treat it as synonym for continuo. Indeed, Sanguinetti points out the superficial resemblance of partimenti to basso seguente keyboard parts, noting this important distinction: basso seguente part represents a synthesis of an existing composition, while partimento is plan for composition not yet in existence (p. 11). Out of this notational practice arose strong tradition of partimenti as pedagogical tools, method by which the Neapolitan masters could pass along information on variety of musical matters-realization of unfigured basses, continuo playing, rules for improvisation, contrapuntal principles, etc.-in concise and orderly manner.Chapter 3 presents thoroughgoing exploration of the history of partimento practices in Italy. Precursors to this tradition are examined, from the early uses of basso continuo, as outlined by Adriano Banchieri in his 1611 treatise L'organo suono, to the early Roman partimenti of Bernardo Pasquini (1637-1710) and, perhaps most significantly, Alessandro Scarlatti. While working in Rome, Scarlatti was student of Pasquini. Sanguinetti cites the connection between these two composers as central to the development of the partimento as both an art form and pedagogical device based on improvisation, tradition that Scarlatti would take with him when he returned to Naples in 1715 to resume his duties there, which included teaching.It is in Naples that the partimento achieved its greatest impact as an instructional device for communicating the principles of composition. Sanguinetti offers reappraisal of the idea of Neapolitan school of composition in chapter 4, and suggests that, since the influence of its adherents had such widespread effect, it might be more appropriate to speak of European school (p. 31). His subsequent outline of the history of the Neapolitan conservatories provides an excellent background for his description of the teaching methods found therein. Chapter 5 gives us synopsis of the pedagogical practices of these institutions, which emphasized the learning of basic bass schemata fused with the study of counterpoint. Both disciplines were necessary to the ultimate goal of fugal composition. …
