Folk music continued soon after. This was generally the sound of the unlearned classes, those that could not write or read. Learned orally, this music was learned and modified time and time again to reflect the personal artistry of the performer. This type of music often portrayed the concerns of the illiterate class. It was usually not supported, but tolerated, but the government and religious leadership. The tradition of folk music still continues as a genre of music to this day throughout the world.
Classical music developed into a less 4 Na 5 rigid modern style of music, mixing with the concept of personal artistry from folk music. Performers would still use either written or learned pieces, but would add their personal touch. The music would sound different each time it was played, even when played by the same performer.
