The Sarawak engkerumungs( xylophone) , musical gongs.

The Canadian Chinese soldiers parachuted down to the mountains of Borneo. I imagine they would have heard this music.

This is a musical instrument of my country, Sarawak

The typical Iban agung ensemble will include a set of 

engkerumungs (small agungs arranged together side

by  side and played like a xylophone)

I asked my hostess if I could try, and she was happy to teach me.

I wasn't synchronized, but my mentor didn't laugh at me.
