Antonio de Cabezón

Cabezón was born in 1510 and died in 1566 at the age of 56. He was a Spanish Renaissance composer and organist.Surprisingly Cabezón was blind, although this didn't seem to stop him, he quickly rose to fame and was later employed by the royal family. He was among the most important composers of his time and was also the first major Iberian keyboard composer.
            The majority of Cabezón's works were published by his son Hernando in a volume called Obras de música para tecla, arpa y vihuela. Together these collections contain 257 pieces, most for organ or other keyboard instruments. He also composed instrumental music for plucked string instruments and ensembles, and vocal music, but only a single vocal piece survives: Invocaión a la letanía, in the Cancionero de la Casa de Medinaceli.
