I saw this on the Classic FM website. A hymn was discovered on a clay tablet in Ugarit, now part of Syria, and is dedicated the Hurrians’ goddess of the orchards Nikkal. This is the oldest melody in existence. It is over 3400 years old.  You can listen to it right here. More on this find at Classic FM.
