In recent years, efforts to achieve interpretations that do justice to the criteria of Â"historical performance practiceÂ" have become de rigueur in the world of early music. Not only has this affected the instruments and performance techniques used by soloists, it also impinges on the Â"musical foundationÂ": the accompaniment. In his figured bass tutor Jesper Bøje Christensen, a teacher at the Schola Cantorum in Basle , shows readers how to produce stylistically accurate figured bass realizations, whether written beforehand or improvised in performance. He has taken an unusual approach: the various figured bass manuals of the early eighteenth century Â- by Dandrieu , St. Lambert , Heinichen , Telemann and others Â- are clearly organized and logically structured and contain practical tips for playing from a figured bass. Christensen has put these sources together and added comments and written-out examples of his own. In this way his tutor not only shows how musicians played at the time, but takes a further step of crucial importance: it succinctly summarizes the way figured bass was taught and studied, thereby creating models for players today.
