RÃÂu RÃÂu ChÃÂu, sometimes shortened to RÃÂu RÃÂu or RÃÂu ChÃÂu, is a Spanish villancico that has attained some contemporary fame as a Christmas carol attributed to the Feast of the Immaculate Conception during Advent.
The villancico is attributed by some sources to Mateo Flecha the Elder, who died in 1553; it has also been described as anonymous. The song also bears a strong resemblance to another villancico, Falalanlera, by Bartomeu CÃÂ rceres, an Aragonese composer. It is known from a single source, the Cancionero de Upsala, published in 1556 in Venice; a unique copy is preserved at the library of the University of Uppsala. The song appears as the fortieth song of that collection. Daniel R. Melamed described the song as "redoubtable", and mentions it as a contender for the best known piece of Renaissance music.
The apparently nonsense syllables rÃÂu rÃÂu chÃÂu are often taken to represent the song of a nightingale, while the context and etymology are compatible with the call of a kingfisher.
Riu translates as river in the Catalan language, in agreement with the birth place of the accredited composer, and was translated as river by the Monkees, where the roaring river prevented a wolf from crossing to attack sheep.
The basic theme of the song is the nativity of Christ. The refrain which gives the villancico its title goes:
The Immaculate Conception is mentioned in the lyrics:
The song also mentions themes of the Incarnation and Christmas:
Classical and early music performers of the song include the Boston Camerata and the Oxford Camerata.
In 1967, the Monkees performed the song live on "The Monkees' Christmas Show", a Christmas episode of their TV series. A studio version was released on subsequent compilation albums (and later on the 2018 album Christmas Party). The Monkees' producer, Chip Douglas, had performed it himself with his former band, the Modern Folk Quartet, on their 1964 album Changes.
The song was performed in Spanish at King's College, Cambridge in their 1992 Christmas Eve broadcast service of "Nine Lessons and Carols".
The song has appeared on recordings including:
