Prehistoric music (previously called primitive music) is a term in the history of music for all music produced in preliterate cultures (prehistory), beginning somewhere in very late geological history. Prehistoric music is followed by ancient music in different parts of the world, but still exists in isolated areas. However, it is more common to refer to the "prehistoric" music which still survives as folk, indigenous or traditional music. Prehistoric music is studied alongside other periods within music archaeology. Findings from Paleolithic archaeology sites suggest that prehistoric people used carving and piercing tools to create instruments. Archeologists have found Paleolithic flutes carved from bones in which lateral holes have been pierced. The disputed 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, such as the Ravanahatha, have been recovered from the Indus Valley civilization archaeological sites. India has one of the oldest musical traditions in the world—references to Indian classical music (marga) are found in the Vedas, ancient Hindu scriptures. Origins of prehistoric instruments Many languages traditionally have terms for music that include dance, religion, or cult. The context in which prehistoric music took place has also become a subject of study and debate, as the sound made by music in prehistory would have been somewhat different depending on the acoustics present. Some cultures include sound mimesis within their music; Often, this feature is related to shamanistic beliefs or practice. It may also serve entertainment or practical functions, for example in hunting scenarios. It is likely that the first musical instrument was the human voice itself, which can make a vast array of sounds, from singing, humming and whistling through to clicking, coughing and yawning. The oldest known Neanderthal hyoid bone with the modern human form has been dated to be 60,000 years old, predating the oldest known Paleolithic bone flute by some 20,000 years, but the true chronology may date back much further. Theoretically, music may have existed prior to the Paleolithic era. Anthropological and archaeological research suggest that music first arose when stone tools first began to be used by hominins. The noises produced by work, such as pounding seed and roots into a meal, are a likely source of rhythm created by early humans. The first rhythm instruments or percussion instruments most likely involved the clapping of
