Ancient Celtic music was not primitive at all, according to a PhD student at Australian National University College of Asia-Pacific who has used 3D printing technology to bring the ancient instrument back to life.

The research began by making a 3D printed model of a bronze artifact dating back to 100BC to 200AD called the Conical Spearbutt of Navan as well as a longer horn from the same period.

He then put the Spearbutt and the longer horn together and realized that he had a complex musical instrument and the Spearbutt was actually a mouthpiece.

“Suddenly the instrument came to life,” PhD student Billy Ó Foghlú, said in a statement. “These horns were not just hunting horns or noisemakers. They were very carefully constructed and repaired, they were played for hours. Music clearly had a very significant role in the culture.”

Ó Foghlú also has a theory about why the pieces were always found apart.

“A number of instruments have been found buried in bogs. The ritual killing of an instrument and depositing it in a burial site shows the full significance of it in the culture,” he said.”Tutankhamen also had trumpets buried with him in Egypt. Contemporary horns were also buried in Scandinavia, Scotland and mainland Europe: They all had integral mouthpieces too.”

He also made a video allowing the prehistoric sounds to be heard once again for the first time in thousands of years.
