Spanish composer and player of the vihuela. Brought up in a noble household, he travelled in Italy before becoming a canon of Seville cathedral in 1547. His Tres libros (1546) contains solo songs to Italian as well as Spanish texts, and examples of all types of music suitable for the solo vihuela: arrangements of vocal pieces (especially by Josquin ), fantasias in a relatively non-contrapuntal style, and variations ( diferencias ) on ground basses. Some of the pieces are arranged in 'suites' consisting of a tiento or prelude followed by a fantasia and an arrangement of a Mass movement.
