Between 7000-5700 BCE, inhabitants of the Neolithic settlement at Jiahu in China's Yellow River basin crafted musical instruments from red-crowned crane wing bones. Archaeologists excavated over 30 bone flutes from burial sites, with six complete specimens representing the world's oldest playable multi-note instruments. These flutes featured 5-8 precisely placed holes producing notes in an octave. Tonal analysis revealed development from four-tone to seven-tone scales. The instruments' presence in elite burials indicates ritual significance and provides evidence of social stratification in this early agricultural society.
