This recording is the oldest known complete musical piece. It was discovered in Turkey; and, it was an epitaph for a man's wife. There are older Greek musical pieces, but, they only exist in fragments.

My question is this. Has there been any more recent discoveries of Ancient Greek music that you're aware of?
