The discovery of the instrument in an area of urn tombs near the sea also posed many questions to scientists, as this kind of musical instrument had previously only been discovered in mountainous areas.

Scientists of the Binh Thuan Museum said that the Ham My lithophone was made skillfully and has special sounds. The museum will invite scientists to further examine the musical instrument.
