Excavations at the Jiahu site in Wuyang County, Henan Province, conducted from the 1980s through the 1990s, recovered more than 30 bone flutes crafted from red-crowned crane ulnae. Zhang Juzhong's 1999 Nature report documented six complete playable specimens dated to approximately 7000 BCE. The flutes feature 5-8 precisely placed finger holes producing pentatonic and heptatonic scales; acoustic analysis confirms intentional tuning rather than chance hole placement. Most flutes were recovered from elite burials, indicating ritual significance within an early agricultural community. The Jiahu finds represent among the earliest known playable wind instruments in the archaeological record.
