The origins of jazz lie mainly with African American musicians. The early songs were not written down but were passed on from musician to musician orally. In Africa, the culture and life remains centered around the village. Everyone participates in some way and the music is connected to everyday events, with songs and dances for such occasions as births, deaths and other rites of passage.

The gregorian chant was a major cultural milestone in the middle ages. it was one of the first codified forms of music meant to be played as written, where previously it was difficult to mass-produce and disseminate any music. what's more, these chants were also some of the first examples of musical notation: the notes and bars of today's music sheets are a reflection of centuries of evolution beginning with these chants. it became official throughout the entirety of the catholic church, meaning that nearly all of europe followed this musical notation and styling.
