Which of these is the oldest musical instrument?

The flute is a family of musical instruments in the woodwind group. Unlike woodwind instruments with reeds, a flute is an aerophone or reedless wind instrument that produces its sound from the flow of air across an opening.

During regular archaeological excavations several flutes, that date to the European Upper Paleolithic have been discovered in caves in the Swabian Alb region of Germany. Dated and tested independently by two laboratories, in England and Germany, the artifacts are authentic products of the Homo sapiens Aurignacian archaeological culture, made in between 43,000 and 35,000 years ago. The flutes, made of bone and ivory, represent the earliest known musical instruments and provide unmistakable evidence of prehistoric music.
