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.
Limenius
Limenius ( ; fl. 2nd century BC) was an Athenian musician and the creator of the Second Delphic Hymn in 128 BC. He is the earliest known composer in recorded history for a surviving piece of music, or one of the two earliest, or the second-earliest, depending first on whether one accepts the proposition of that the composer of the First Delphic Hymn is named Athenaeus and, second, whether that hymn was composed in the same year as the Second Hymn, or ten years earlier. Limenius was a performer on the kithara and, as a professional musician performing in the Pythaïs (the liturgical embassy to the cult centre of Pythian Apollo at Delphi), he was required to belong to one of the guilds of the Artists of Dionysus .
