Cipriano de Rore (occasionally Cypriano) (1515 or 1516 – between 11 and 20 September 1565) was a Franco-Flemish composer of the Renaissance, active in Italy. Not only was he a central representative of the generation of Franco-Flemish composers after Josquin des Prez who went to live and work in Italy, but he was one of the most prominent composers of madrigals in the middle of the 16th century. His experimental, chromatic, and highly expressive style had a decisive influence on the subsequent development of that secular music form.
Little is known of Rore's early life. His probable birth years (1515/1516) are known from his age at death (49, recorded on his tombstone in the cathedral in Parma), and his probable birthplace was a small town in Flanders, Ronse (Renaix), right on the boundary between the French- and Dutch-speaking areas. Recent research has established that his parents were Celestinus Rore (died before 1564) and Barbara Van Coppenolle, and he had at least two siblings, Franciscus and Celestinus. The family was active in Ronse at least since 1400, and their coat of arms appeared both on his personal seal and his tombstone in Parma Cathedral.
Where he got his musical training is unknown. Based on a suggestive phrase in a 1559 madrigal dedicated to Margaret of Parma, the illegitimate daughter of Holy Roman Emperor Charles V, which implied a long association with her, he may have accompanied her when she went to Naples in 1533, prior to marrying into the Medici family. Margaret was born in a town within walking distance of Rore's birthplace. Prior to that speculative trip Rore may have had some early music instruction in Antwerp. Many gifted singers from the Netherlands went to Italy as children or adolescents, often when discovered by visiting nobility; both Lassus and Giaches de Wert traveled to southern Italy in similar circumstances. When Margaret married Alessandro de' Medici in 1536, Rore may have gone his own way; however, he is believed to have received some of his music education in Italy during his period of service with Margaret.
While it has long been claimed that he studied in Venice with Adrian Willaert, and that he was a singer at San Marco, no specific documentation of either of these events has been found; some dedicatory material in his Venetian publications mentions him as a "disciple" or "follower", but not specifically as a student. Yet he was closely connected with Willaert and his associates for much of his career, and visited Venice at least once before 1542. Beginning in this year, documentation on Rore's whereabouts becomes more clear. A letter written on 3 November 1542 indicates he was at Brescia, where he was known to have remained until 16 April 1545. It was during this period that he began to acquire fame as a composer, publishing, with the assistance of the Venetian printer Scotto, his first book of madrigals in 1542, as well as two books of motets in 1544 and 1545. The reprints of these works two years later by both Scotto and Gardane indicated their high regard. Their technical mastery, and stylistic indebtedness to Willaert and his circle, make an early connection with Venice a reasonable supposition.
