Franco was born in Galizuela in Extremadura, a source region for many people who came to the New World in the 16th century. He was trained in music as a choir boy, and later apprentice and journeyman, at Segovia cathedral by Gerónimo de Espinar, who may also have been a teacher of Tomás Luis de Victoria. While a youth he met and befriended Lázaro del Álamo, who was to precede him as maestro de capilla in Mexico City. Most likely Franco went to Nueva España in the 1550s, though there is no record of his activities until 1571 when he appears in the records as maestro de capilla of the cathedral of Santiago de Guatemala, which had been elevated to cathedral rank in 1534. That magnificent building had been newly constructed in the new site in the valley of Panchoy, present-day Antigua Guatemala, after the city had to be moved from the previous site in Almolonga, beginning in 1542. Franco left that position in 1574 after a series of budget cuts that affected his salary, and undertook the journey to Mexico. Here he was fortunate to find the position of maestro de capilla of the new cathedralvacant. He was appointed the new chapel master in 1575, where his old friend Lázaro del Álamo had been maestro de capilla from 1556 to 1570. Franco was clearly a well-respected and beloved figure, since he was granted a prebend in 1581 and contemporary documents contain numerous references to his exemplary character and musicianship. He resigned in 1582 during a period of financial difficulties in Mexico City, and died in 1585. He is buried in the cathedral's main chapel.
Work and influence
Franco wrote 20 motets which survive, as well as 16 Magnificat settings and a setting for four voices of the Lamentations of Jeremiah. He seems to have written no masses, an unusual omission for a composer who headed a Spanish chapel choir, but it is possible that much of his music has been lost. Some hymns in the Nahuatl language by a composer of the same name are now presumed to be the work of a native composer who took Franco's name, as was the custom, on his conversion to Christianity and baptism. Franco's style is related to that of other Spanish composers of the period, though more conservative, treating dissonance carefully, avoiding chromaticism and virtuosity; indeed tending towards austerity. His settings of the Magnificat were influenced by those by Cristóbal de Morales. The voice range of his works is limited, and may reflect the singing abilities of his choirs, which were not up to the musical standards of those in Europe. Franco is the earliest known composer in Guatemala; his two pieces in the archives of the Guatemala cathedral, a Lumen ad revelationem and a Benedicamus Domino, are the earliest surviving manuscripts from the area. Other composers preceded him in Mexico, but he was considered by his contemporaries to be the finest of the 16th century there.
