I finally got to take a look at this. The development of "waila" or "chicken scratch" music among the Tohono O'Odham people of southern Arizona and northern Sonora, Mexico is similar -- a local adaptation of the 19th century European styles, in this case also filtered through the Mexican/norteño music.

Here, it comes combined with a low-amplitude dance style made for doing through a long, hot, desert night.

Waila Music

annual Waila Festival in Tucson, started to honor the tradition and share it with the urban community in Tucson
