Pablo Minguet y Yrol's Academia Musical of 1752, M891 in the Bíblioteca Nacional of Madrid, is a loosely organized collection of tutors for thirteen musical instruments: guitar, tiple, mandola, cittern, bandurria, psaltery, clavichord [i.e., keyboard], organ, harp, violin, transverse flute, recorder, and flageolet. The tutors concerning the guitar and related instruments are by far the most comprehensive; topics covered include basic playing technique, figured-bass accompaniment, and notation, both mensural and tablature. Most musical examples are given in both types of notation. The thesis is a complete translation of the Academia Musical, including the texts of the illustrations, with an introductory commentary giving the historical background of music education in eighteenth-century Spain, a brief review of European musical-instrument tutors in general, and an analysis of Minguet's tutors in particular.
