The oldest known piece of music

This is my first post of 2018! And I would like to talk about music written (many many) years ago. According to this article, hymn honoring the Sumerian ruler Lipit-Ishtar was found on a 4000 year old clay tablet which includes instructions and tunings. And there is another "not quite" old Greek tune called “Seikilos Epitaph” from first century A.D. which is complete enough that modern musicians were actually able to perform! This is a beautiful rendition played on harp.
