Medio registro alto de Primer Tono

Francisco de Peraza was a very famous organ virtuoso.

He was appointed organist at the Cathedral of Sevilla at the early age of eighteen, and he deserved to be buried in the cathedral, in the chapel of the Vírgen de la Antigua.

In 1599 Francisco Pacheco wrote in his "Libro de descripción de verdaderos retratos" (Book of description of truthful portraits) that Francisco Guerrero, the master of Spanish vocal music (1528-1599), "embraced" Francisco, "clasped his hands, and asked for his permission to kiss them"; that "an angel lived in his fingers"; and that he "was the inventor of the medios registros" (tientos partidos).

Sadly, this tiento is his only surviving work from an output that Pacheco estimates at over two thousand pieces.
