Ríu Ríu Chíu
Spanish villancico
Ríu Ríu Chíu, sometimes shortened to Ríu Ríu or Ríu Chíu, is a Spanish villancico that has attained some contemporary fame as a Christmas carol attributed to the Feast of the Immaculate Conception during Advent.
Origins
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 Càrceres, 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 ríu ríu chíu 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.
Lyrics and themes
The basic theme of the song is the nativity of Christ. The refrain which gives the villancico its title goes:
"[With a cry of] Ríu, ríu, chíu, the kingfisher, God kept the wolf from our Lamb."
The Immaculate Conception is mentioned in the lyrics:
"The raging wolf sought to bite her, but God Almighty knew (how) to defend her; He chose to make her so that she could not sin; no original sin was found in that virgin."
The song also mentions themes of the Incarnation and Christmas:
"This one that is born is the Great King, Christ the Patriarch clothed in flesh.
