The Cirandas of Villa-Lobos are based on songs sung by children while playing dancing games. Most of these songs are familiar to Brazilians, but for others it is unclear what is the original melody, and what was created by Villa-Lobos. In the 1940s, in his work as director of music education for all of Brazil, he published a book called Guia Practica in which, among other things, he collected and arranged a great deal of Brazilian folk material. Among the pieces in that collection are originals for the 16 Cirandas for solo piano. I am posting scans of those songs, in some cases multiple versions. I hope this will prove useful to people studying Villa-Lobos' music.
