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.
Christ ist erstanden
"Christ ist erstanden" (Christ is risen) is a German Easter hymn, and is possibly the oldest Christian liturgical German song. It has inspired music by composers such as Ludwig Senfl and Heinrich Schütz (from the sixteenth and seventeenth centuries respectively) through to modern composers such as Oskar Gottlieb Blarr and Enjott Schneider, and has appeared in 45 hymnals, including the current German Catholic and Protestant hymnals. Translations and paraphrases include a version by Catherine Winkworth which has appeared in 231 hymnals. "Christ ist erstanden" also inspired Martin Luther to write "Christ lag in Todes Banden", deriving the melody from it.
