According to the Internet source given below, Francisco Guerrero was a Spanish composer of the Renaissance. He was born and died in Seville.
Guerrero's early musical education was with his older brother Pedro. He must have been an astonishing prodigy, for at the age of 17 he was already appointed maestro de capilla (singing master, i.e. music director) at Jaén Cathedral. A few years later he accepted a position in Seville. Apparently during this time he was much in demand as a singer and composer, establishing an exceptional reputation before his thirtieth birthday; in addition he published several collections of his music abroad, an unusual event for a young composer.
Guerrero's music was both sacred and secular, unlike that of Victoria and Morales, the two other Spanish 16th century composers of the first rank. He wrote numerous secular songs and instrumental pieces, in addition to masses, motets, and Passions. He was able to capture an astonishing variety of moods in his music, from ecstasy to despair, longing, joy, and devotional stillness; his music remained popular for hundreds of years, especially in cathedrals in Latin America. Stylistically he preferred homophonic textures, rather like his Spanish contemporaries, and he wrote memorable, singable lines. One interesting feature of his style is how he anticipated functional harmonic usage: there is a case of a Magnificat discovered in Lima, Peru, once thought to be an anonymous 18th century work, which turned out to be a work of his.
