Origins of music

• The origins of human music are unclear due to various contexts and purposes.

• Archaeologists have found musical instruments in Egyptian and Indus civilization sites.

• Some theories suggest human music co-originated with human language, but evidence is iffy.

• Scientists have studied music among chimpanzees, finding spontaneous drumming behavior in both Western and Eastern chimpanzees.

• The observed drumming behavior suggests precursors to human musical rhythm evolved from traits in common ancestors of humans and chimpanzees.
