Wie mit aller Volkommenheit und Meisterschaft das Klavichord zu spielen sei 1565 - Santa Maria, Tomás de Fray 1510-1570; Harich-Schneider, Eta 1894-1986; Boadella, Ricard (Lippstadt Kistner & Siegel, 1962)
This book is a comprehensive work on keyboard technique of the time. Its principal aim is to teach how to improvise in a fugal style, but to get to that point, difficult to the most accomplished musicians of any age, it includes detailed treatments of the rudiments of music, the eight church modes, ornaments, touch, articulation, fingering, and counterpoint, including a categorization of four-note chords, rather similar to what Pietro Aron had written several decades before in Italy (which work Santa María may have used as a source). The classification of chords is especially significant, for this is the period in music history during which composers began to think in terms of harmonic progression as a generative mechanism rather than purely the happenstance of intersecting, independent melodic lines. Santa María's book also gives instruction for creating music using the paired imitation technique of Josquin des Prez, who he clearly held to be the master of the style.
