What was the earliest known attempt to notate a piece of music?

The earliest known attempt to notate music dates back to ancient Mesopotamia around 2000 BCE, where the Sumerians used cuneiform script on clay tablets to indicate musical instructions and scales. A notable example is the "Hurrian Hymn No. 6," discovered in the ancient city of Ugarit (modern-day Syria), which includes notations for a lyre performance. This suggests an early form of musical notation that aimed to preserve and transmit musical compositions.
