Singing Bowl Courses

Hi.  Does anyone know of a good place to take singing bowl courses in Kathmandu or Pokhara?

Thanks!

I have seen a long-time established singing bowls centre in Boudhanath, just some 50mtrs away from the main gate of White Monastery (which anyone knows over there). No idea how good is the place and what are their costs, but the place looks reliable and there is an ad featuring "therapy and classes available".
