Looking to find out the name and origin of this song

Question

Here is a clip of the Spanish Children's song

My cousin started singing it, but he made up words. However, the melody sounded vaguely familiar, so I sang along.

Answer 1

Oddly, this song has a very interesting history. The title in Spain is "Arrorró mi niño". If you Google the title along with the name Francisco García-Talavera, you will find several versions of an interview that researcher gave about the song.

Long story short, it is originally a lullaby of the Berber people, and Spain picked it up when they were under Islamic rule.

In Mexico people sing "Duérmete mi niño" to the same tune.
