Since Scarlatti was a prolific composer of sonatas, Harper usefully lists only those works connected to his career in Portugal. . . . This volume serves as a most useful guide to Portuguese composers, including those from the Azores and Madeira as well as the mainland. Harper's introduction. . . provides a welcome overview of Portuguese history from the 1700s to the present. ... As one listens to the accompanying CD, on which the author skillfully renders a wide selection of works from the eighteenth to twenty first centuries, from sonatas to electro-acoustic compositions, one realizes just what pleasant surprises we have deprived ourselves of through our general ignorance of Portugal's musical heritage, particularly its lustrous history of keyboard music. There are many hours of listening pleasure to be gained from this repertory. . . . Harpers triune approach, embracing historical narrative, easy-to-access bibliographic information, and actual recordings, will do much to stimulate interest not only in well-established figures such as Seixas but also in less-renowned composers like Luis Pipa. . . . Nancy Lee Harper is a leader among those mapping the terrain.
