Gyaling

Hello to all!

I would like to ask if anyone knows if there have ever been any
ethnomusicological cents or frequency measurements made for the
Gyaling (a Shawm used in Buddhist ritual ceremonies)?

If any are aware of where I might be able to obtain this information
about the Gyaling, or any other Buddhist ritual orchestra
instruments, please let me know, and I'll be eternally grateful.

Kind thanks,

Jacky Ligon
