Estudio y edición crítica a cargo de Luis Antonio González Marín.
As for Nebras keyboard music, which from the start was to be his main occupation, we have a sad panorama of scattered, late sources, and often of doubtful - if not erroneous - attribution, until the appearance and subsequent study of the manuscript to which the present edition is dedicated. This notebook was discovered in the Music Archive of the Cathedrals of Zaragoza. The content of the manuscript consists of a set of thirty-one pieces grouped in eight large works in several movements, which often depart somewhat from the Scarlattian sonata model so common in eighteenth-century Iberian keyboard music and which link with other traditions of keyboard music: the purely Hispanic (in some examples of great intentos or fugues, imitative compositions derived from the ancient tientos) and also other European traditions, such as the French, detectable in numerous dance movements. Nebra gives the name sinfonía to two of these large-scale compositions in several movements, so that in this edition, respecting the name given by the author, the editor used such a name for the series of eight pieces, which could probably also have been called suites, ordres or even sonatas.
