Xtoles (Canto al sol)

Hola, encontré esta explicación en la enciclopedia Grove:
The pre-Columbian dance called ix tolil in the Chilam Balam of Tizimín (1593) continued in 1941 to be ‘the most important dance of the modern Mayas’. In that year Gerónimo Baqueiro Fóster published a pentatonic melody called Xtoles (from ix tolil, ‘ribbon dance’). He claimed to have heard the air countless times during his early youth in Mérida, the capital of Yucatán, as well as elsewhere in the peninsula and proposed it as the sole ‘Maya’ survival amid a welter of popular music of foreign origin. Frequently reprinted after 1941 and adopted as a ‘theme song’ by the touring Ballet Folklórico de Mexico (directed by Amalia Hernández), Xtoles was first collected by José Jacinto Cuevas (1821–78), who included a triple-metre version of it in his Mosaico yucateco. Equally well ascribable to Africans, who by 1604 outnumbered Spaniards at Mérida, the melody cannot be authenticated as truly Mayan for lack of any music of a popular or folkloristic nature written down in Yucatán before the middle of the 19th century. On the other hand, the cathedral organist at Mérida in 1596 was Gaspar Antonio Chi (Xiu) (1531–c1610), a Maya priest’s son who according to Sánchez de Águilar ‘sang plainsong and figural music excellently, and after being holpop [choirmaster] at Tizimín became organist of Mérida Cathedral and the governor’s official interpreter’.
