Bails, Benito. (1730–1797)
Lecciones de Clave, y Principios de Harmonia
Madrid: Joachin Ibarra. 1775. First edition. 4to. [iv] 291 pp, lacking the folding plate of the keyboard, scattered foxing, but otherwise very good. Full leather binding, gilt stamped, title plate to spine partially cracked. Palau (21923) notes: "Es traduccion de la obra de Antonio Bemetzrieder y esta muy bien impresa" and the work is indeed beautifully printed, with musical examples throughout and including a charming engraving at the head of the first lesson, featuring three putti playing around a harpsichord. An interesting and unusual keyboard treatise written by a modestly important Spanish mathematician and architect. (10494)Book Classical Music
