Prehistoric music can only be theorized based on findings from paleolithic archaeology sites. Flutes are often discovered, carved from bones in which lateral holes have been pierced; these are thought to have been blown at one end like the Japanese shakuhachi. The Divje Babe flute, carved from a cave bear femur, is thought to be at least 40,000 years old. Instruments, such as the seven-holed flute and various types of stringed instruments have been recovered from the Indus Valley Civilization archaeological sites.[4] India has one of the oldest musical traditions in the world—references to Indian classical music (marga) can be found in the ancient scriptures of the Hindu tradition, the Vedas.[5] The earliest and largest collection of prehistoric musical instruments was found in China and dates back to between 7000 and 6600 BC.[6] The Hurrian song, found on clay tablets that date back to the approximately 1400 BC, is the oldest surviving notated work of music.
