Seikilos epitaph
The Seikilos epitaph is the oldest surviving complete musical composition, including musical notation, from anywhere in the world. The epitaph has been variously dated, but seems to be either from the 1st or the 2nd century AD. The song, the melody of which is recorded, alongside its lyrics, in the ancient Greek musical notation, was found engraved on a tombstone (a stele) from the Hellenistic town Tralles near present-day Aydın, Turkey, not far from Ephesus. It is a Hellenistic Ionic song in either the Phrygian octave species or Iastian tonos. While older music with notation exists (for example the Hurrian songs), all of it is in fragments; the Seikilos epitaph is unique in that it is a complete, though short, composition.
Prehistoric music
The oldest flute ever discovered may be the so-called Nicholas flute, found in the Hohle Fels cave, Germany in 2008, though this is disputed. The item in question is a fragment of the femur of a juvenile cave bear, and has been dated to about 43,000 years ago. However, whether it is truly a musical instrument or simply a carnivore-chewed bone is a matter of ongoing debate. In 2012 some flutes, that were discovered years earlier in the Geißenklösterle cave, received a new high-resolution carbon-dating examination yielding an age of 42,000 to 43,000 years.
