Flutes of the Mississippian culture have been found that appear to have the two-chambered design characteristic of Native American flutes. They were constructed of river cane. The earliest such flute is curated by the Museum Collections of the University of Arkansas, Fayetteville. It was recovered in about 1931 by Samuel C. Dellinger and more recently identified as a flute by James A. Rees, Jr. of the Arkansas Archeological Society. The artifact is known colloquially as "The Breckenridge Flute" and was conjectured to date in the range 750–1350 CE.
